Three Types of 40G QSFP+ Transceivers for Long Distance Transmission

Nowadays, people have access to data at all times and at everywhere, which gives rise to the rapid development of big data technology. During the application of big data technology, transceiver has become an indispensable component, which can help executives to get their data in real-time. Recently, 40GbE network has replaced 10G Ethernet network and has been used worldwide. For 40GbE network deployment, high-density cabling is the basic requirement. Also, optical components for high-speed data transmission are necessary. This article aims to introduce three types of 40G QSFP+ transceivers for long distance transmission—QSFP-4X10GE-IR, QSFP-40G-PLRL4 and QSFP-4X10G-LR-S.

40G QSFP+ transceiver

QSFP-4X10GE-IR Transceiver

Designed with MTP interface, the parallel QSFP-4X10GE-IR transceiver offers 4 independent transmit and receive channels, each capable of 10Gbps operation. It utilizes 12-ribbon single-mode fiber cable with female MTP/MPO connector to realize 40Gbps data link with transmission distances up to 1 km.

QSFP-40G-PLRL4 Transceiver

The QSFP-40G-PLRL4 transceiver uses 12-fiber MTP interface to achieve 40Gbps parallel transmission, supporting maximum data link lengths up to 1.4 km. The cable type required for QSFP-40G-PLRL4 transceiver is an APC (angle polished connector) single-mode 12-fiber MTP cable. APC is the only available type for single-mode MTP-12 fiber.

QSFP-4X10G-LR-S Transceiver

The QSFP-4X10G-LR-S transceiver is a parallel 40Gbps QSFP+ optical module. It supports link lengths of up to 10 km on G.652 single-mode fiber. It enables high-bandwidth 40G optical links over 12-fiber parallel fiber terminated with MPO/MTP female connector. It can also be used in a 4x10G mode for interoperability with 10GBASE-LR interfaces up to 10 km.

When reading this, you may find that all these three types of 40G transceivers are designed with MTP interface and use parallel transmission. In parallel transmission, data signals are sent sequentially on the same channel. In addition, they all use 1310nm wavelength and can transfer data signals up to at least 1 km. What’s more, they are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA) and they support Digital optical monitoring (DOM).

Working Principle

Because the structures of these three types of 40G transceivers are similar, their working principles are similar, too. The single-mode cable terminated with 12-fiber MTP connector plugged into the 40G transceiver carries the 40G signal over only 8 of the 12 fibers, remaining 4 fibers unused. The 8 used fibers are mapped as 4x10G Tx and Rx pairs. We can easily understand the working principle of these three types of 40G QSFP+ transceivers from the figure below. In the transmit side, the transmitter converts parallel electrical input signals into parallel optical signals through the use of a laser array. Then the parallel optical signals are transmitted parallelly through the single-mode fiber ribbon terminated with MTP/MPO connector. While in the receive side, the receiver converts parallel optical input signals via a photo detector array into parallel electrical output signals.

Application

Many data centers are in the process of 10G to 40G migration. To make migration path smooth, we can use 40G transceivers together with MTP cable. Take QSFP-40G-PLRL4 transceiver for example, we can simply use MTP-LC harness cable to connect one QSFP-40G-PLRL4 transceiver and four 10GBASE-LR SFP+ transceivers. Here is a figure for you to have a better understanding of the connectivity. In addition, for 40 connectivity, we can use MTP trunk cable to connect two QSFP-40G-PLRL4 transceivers to make the optical links. Using 40G QSFP+ transceiver for high-speed long distance transmission over single-mode fiber is a cost-effective solution.

Things You Must Know About MTP Cassette

With increasing demand for faster data transmission speed, 40G and 100G network have been widely applied to data centers. When it comes to cabling system, data center managers usually prefer fiber optic components which can provide high bandwidth, high port density, easy management, future data rates migration and security monitoring. Modular system is ideal option which can realize simple high-density installation and tidy cable management. MTP cassette, as the key component of the modular system, is widely used for high-density cabling in data centers. This article will talk about things you must know about MTP cassette.

Overview of MTP Cassette

MTP fiber optic cassette is pre-terminated and pre-tested enclosed unit. It is usually fitted with 12 fibers or 24 fibers. Structured with LC or SC adapters on the front side of the cassette and MTP adapters at the rear of the cassette, MTP fiber optic cassette provides secure transition between MTP and LC or SC discrete connectors. Therefore, it is commonly used to interconnect MTP backbones with LC or SC patching. Supporting various network cabling standards, the cassette is easy to mix, match, add and replace as the connectivity needs grow or change. Here is a figure of 12-fiber and 24-fiber MTP-LC cassette for you.

12-fiber and 24-fiber MTP-LC cassette

Working Principle of MTP Cassette

MTP cassette serves to realize the transition from small diameter ribbon cables terminated with MPO MTP connector(s) to the more common LC or SC interfaces used on the transceiver terminal equipment. Typically, the fan-outs incorporate LC or SC connectors plug into LC or SC adapters on the front side of the cassette and MTP MPO fiber connector(s) plug into MTP adapter(s) mounted at the rear of the cassette. One or more MTP fan-out assemblies can be installed inside the cassette to connect up to two 12-fiber ribbon cables for a total of 24 fibers. Alignment pins are pre-installed in the MTP connector located inside the cassette. These pins precisely align the mating fibers in the MTP connectors at either end of the array cables that plug into the cassettes.

For application, MTP cassette can be easily found in 10G, 40G and 100G network applications in data center. For 10G connectivity, MTP cassette is used to connect 10G device to 10G device, especially when the distance between two devices is too long. And for 40G connectivity, MTP cassette is used to connect 40G device to 40G device. Besides, it can provide the smooth path for 10G to 40G migration and 40G to 100G migration. What’s more, it is important to buy MTP cassette from MTP cassette modules manufacturers, or you may get terrible network performance.

Advantages of MTP Cassette

MTP cassette has many advantages.

Advantage 1. It allows for rapid deployment of high density data center infrastructure as well as improved troubleshooting and reconfiguration during moves, adds and changes.

Advantage 2. It is designed to reduce installation time and cost for an optical network infrastructure in the premises environment.

Advantage 3. As MTP component, it features superior optical and mechanical properties.

Advantage 4. It can provide optimized performance for low insertion losses and power penalties in tight power budget, high-speed network environments.

Advantage 5. It has internal fiber management which keeps the fibers from bending too tightly.

Advantage 6. It has the array connection located in a recess in the cassette housing which provides better protection.

Advantage 7. A 12-fiber or 24-fiber cassette can be mounted in 1U scaling up to 72 or in 3U scaling up to 336 discrete LC connectors which is convenient for high-density cabling.

Conclusion

Characterized with fast installation, high density and high performance cabling for data centers, MTP components gain great polarity among the world. MTP cassette, able to deliver high optical performance, rapid and error-free installation and reliable robust operation, is a great choice for high-density cabling system. And I hope after reading this article, you can have a better understanding of MTP cassette.

Some Thoughts Required Before MTP Cabling

To meet system bandwidth needs and provide higher density cable connectivity, building backbones and data center backbones are migrating to 40G and 100G Ethernet network. Making the migration path smooth has become a hotspot. Network designers are turning to MTP components which can provide cost-effective solutions for cabling systems of data centers. We know that MTP components are designed with complex structures, so before you start your 40G Ethernet network deployment, there are a few aspects of MTP cabling that require some thoughts.

Polarity

First and foremost is the polarity. With the LC connector typically used for 1G and 10G fiber cables, this isn’t a big deal. You can flip the two fiber strands on the LC connector easily to invert the polarity if needed. However, the MTP connector is fixed, you can’t change the ordering of the strands in the connector. Take 12-fiber MTP trunk cable for example, it is made up of 12x individual strands of fiber and one 12-fiber MTP connector on each end. Typically in 40G Ethernet network deployment, the 12-fiber MTP cable transmits optic signals on first 4x strands, and receives optic signals on the last 4x strands. The 4x “transmit” strands in MTP connector on one end need to end up at the “receive” strands in MTP connector on the other end. In other words, 8 of the 12 fibers are used to provide 40G parallel transmission and the polarity of the cable has to be inverted between the two devices. In addition, there are three polarity methods for MTP cabling. Each of them has different features. It is recommended that a method be selected in advance according to the specific requirements of the cabling situation and maintained consistently throughout an installation.

Gender of MTP Connector

Another issue with MTP components to take into consideration is the gender of the connector going into the adapter matter. There are male connector and female connector. And the former one has pins while the latter one has no pins. One cable going into a MTP adapter needs to have a male connector and the other cable must have a female connector. This is not initially obvious to those who have little knowledge about MTP components. If you only have MTP cables with female connectors, they can be snapped into the adapter just fine, but will not work. The figure below shows the difference between the structure of male and female MTP connector.

male and female MTP connector in MTP cabling

Key Position of MTP Adapter

MTP adapter, or MTP coupler, is simple plastic rectangle that holds two MTP connectors together. The other important factor to note about MTP adapter is that they can be either key-up to key-up, or key-up to key-down, and this corresponds to the key position of MTP connector. When the key sits on top, this is referred to as the key up position. On the contrary, when the key sits on bottom, we call it key down position. On a key-up to key-up adapter, the keys are pointed the same direction on both of the connectors. While on a key-up to key-down adapter, the keys are on opposite sides. This can effect the polarity of the fiber link. To have a better understanding of this, here is a figure for you.

key position of MTP adapter in MTP cabling

Conclusion

Being able to provide an easy migration path for higher data rates that will require parallel optics such as 40/100G Ethernet network, MTP cabling is commonly used by network designers to satisfy the increasing demands for higher transmission speed and cabling density. However, before the installation, three major problems—polarity, gender of MTP connector and key position of MTP adapter have to be solved to ensure the smooth data transmission over the optical links.

MTP Trunks and Breakouts for 10G to 40G Migration

With the rapid development of datacom, 10Gbps is no longer enough for massive data transmission. Many data center managers set their sights on 10G to 40G migration. However, it is not possible to upgrade all 10G equipment in the cabling system because of the high cost. Therefore, finding a cost-effective solution for the migration has become a hotspot. We know that MTP cable gains great popularity among data center managers since it can provide fast installation, high density and high performance cabling for data centers. By using MTP trunk cable and MTP breakout cable respectively, there are two solutions for 10G to 40G migration. And this article is going to share these two solutions with you: MTP trunks and MTP breakouts.

Overview of MTP Trunk Cable and MTP Breakout Cable

Before we come to the migration solutions, let’s have a brief overview of MTP trunk cable and MTP breakout cable. MTP trunk cable, terminated with MTP connectors at both ends, can create the permanent fiber links between panels in a structured environment. It is typically used as backbone or horizontal cable interconnections. With efficient plug and play architecture, MTP trunk cable can greatly reduce the installation and maintenance costs. In networking applications, 12-fiber and 24-fiber MTP trunk cables are commonly used: 12-fiber MTP trunk cable is normally for 40G Ethernet network, while 24-fiber MTP trunk cable is normally for 100G Ethernet network.Here is a figure of MTO trunk cables for you.

MTP trunk cables

MTP breakout cable, also named MTP fanout cable or MTP harness cable, is terminated with a male/female MTP connector on one side and several duplex LC/SC connectors on the other side, providing a transmission from multi-fiber cables to individual fibers or duplex connectors. It is typically used to connect equipment in racks to MTP terminated backbone cables. MTP breakout cable is designed for high density applications which require high performance and speedy installation without on-site termination.Here is a figure of MTP breakout cables for you.

MTP breakout cables

MTP Trunks for 10G to 40G Migration

For 10G to 40G migration, you can use the MTP trunk cable. Also, MTP fiber patch panel can be used to fulfill the data transmission link. With forty-eight LC duplex adapters on the front and twelve 8-fiber MTP adapters on the rear, the high density 40G QSFP+ breakout patch panel acts as a middleman between 10G to 40G connection. The figure below shows the connectivity method. From the left to the right, four 10G SFP+ transceivers are plugged in the SFP+ interfaces on the switch on one side, then the SFP+ transceivers are connected with the front LC ports of MTP fiber patch panel by LC duplex patch cables. With the use of MTP trunk cable, the rear MTP ports of MTP fiber patch panel are linked with one 40G QSFP+ transceiver. Finally, the whole optical link is accomplished by plugging the 40G QSFP+ transceiver in the QSFP+ interface on the switch on the other side.

MTP Trunks for 10G to 40G Migration

MTP Breakouts for 10G to 40G Migration

For 10G to 40G migration, using the MTP breakout cable is a simple way. As shown in the following picture, four 10G SFP+ transceivers are plugged in the SFP+ interfaces on the switch on one side, while one 40G QSFP+ transceiver is plugged in the QSFP+ interface on the switch on the other side. Then the MTP to LC breakout cable connects the four 10G SFP+ transceivers with the 40G QSFP+ transceiver. Finally, the data can be transmitted from 10G switch to 40G switch through the MTP to LC breakout cable smoothly.

MTP Breakouts for 10G to 40G Migration

Conclusion

For data centers which are in the process of 10G to 40G migration, connecting 40GbE equipment with existing 10GbE equipment is what must be experienced. In addition, carrying out the migration smoothly is the greatest concern of many data center managers. In order to solve the problem, MTP trunk cable and MTP breakout cable can provide two cost-effective and reliable solutions which can ensure smooth migration path and high performance of the network.

How Much Do You Know About MTP-8 Solution?

It is not difficult to find that MTP components are widely used for high density application in data centers. As 40G and 100G network has been utilized by many data centers, two common types of cabling solutions are popular among data center managers—MTP-12 solution and MTP-24 solution, which use links based on increments of 12 and 24, such as 12-fiber MTP MTP trunk cable and 24-fiber MTP MTP trunk cable. In addition to MTP-12 solution and MTP-24 solution, there is another MTP solution—MTP-8. So how much do you know about MTP-8 solution? This article will guide you to learn about MTP-8 solution.

Overview of MTP-12 Solution and MTP-24 Solution

Before we come to MTP-8 solution, let’s have a brief overview of MTP-12 solution and MTP-24 solution. In 40G networking applications, a 12-fiber MTP fiber connector is used: 10G is sent along each channel or fiber strand in a transmit and receive direction, and 8 of the 12 fibers are used to provide 40G parallel transmission. In 100G network applications, a 24-fiber MTP fiber connector is used: 10G is sent along each channel or fiber strand in a transmit and receive direction, and 20 of the 24 fibers are used to provide 100G parallel transmission. Here are two figures for you to have a better understanding of this.

MTP-12 Solution

MTP-12 Solution

MTP-24 Solution

MTP-24 Solution

Overview of MTP-8 Solution

In a MTP-8 solution or Base-8 solution, 8-fiber MTP MTP trunk cable, 24-fiber or 32-fiber MTP MTP trunk cable can be used to transmit data. In brief, MTP-8 solution uses cable links based on increments of the number “eight”. Since MTP-12 solution and MTP-24 solution have been using in the data center for years, you may ask is t necessary to use MTP-8 solution? From the figure below, we can find that in fiber optic industry, optical transceiver roadmap changes rapidly from 10G to 40G, 100G and even up to 400G. With faster speeds spreading out into data center racks and SANs, there is a need for a more manageable grouping. For 40G network applications and above, optical signals are usually carried over eight fibers, and terminated at the switch in a MTP-8 QSFP transceiver which combines eight fibers.

40G 100G 400G use MTP-8 solution

From the figure, we can also learn that for Ethernet transmission ranging from 40G to 400G, all roads lead to 2-fiber and 8-fiber solution. For 40G/100G and future 400G applications, the use of 12-fiber MTP solution would result in 33% of the optical fibers unused. Thus it is expected that for 400G application, MTP-8 will gain widespread market acceptance.

Advantages of MTP-8 Solution

There are two primary advantages of MTP-8 solution—flexibility and 100% fiber utilization. Being wholly divisible by number “2”, MTP-8 solution can be easily used for two-fiber transceiver systems, just as MTP-12 solution can be. And for those who have deployed 12-fiber or 24-fiber MTP MTP trunk cable, how to ensure the 100% fiber utilization? MTP-8 solution can. You can use conversion cords or modules to transition two 12-fiber or one 24-fiber  trunk from backbone cabling into three 8-fiber MTP for 40G/100G equipment connection. But in this process, conversion modules will introduce additional insertion loss into the channel and conversion cords. Thus deploying MTP-8 solution directly can ensure 100% fiber utilization without the additional cost and insertion loss of MTP-12 to MTP-8 conversion devices. In a word, for the most common 40G/100G/400G transceiver types, MTP-8 solution offers the most flexibility and uses the fibers to the fullest.

Conclusion

MTP-8 solution is considered as the most cost-effective connectivity solution for supporting the current and future 8-fiber applications. Anyone with a near-tern migration plan to adopt 40G or 100G in the data center will benefit a lot from adopting MTP-8 solution.
