Applications of MTP Conversion Cable

We know that MTP/MPO cable is a great option for nowadays data center fiber optic cabling which needs higher and higher cabling density and transmission capability. In most cases, 12-fiber MTP cable is used to realize 10G to 40G or 40G to 40G connection. However, there is a problem in this cabling system—only eight fibers of the 12-fiber MTP cable are used (four fibers for transmitting and four fibers for receiving), leaving the middle four fibers unused. That means using 12-fiber MTP cable cannot achieve 100% fiber utilization. To solve this problem, MTP conversion cable is available on the market. And this article is going to introduce applications of MTP conversion cable in data center.

1×3 MTP Conversion Cable

This type of MTP conversion cable is usually used for 40G to 120G connection. It is terminated with one 24-fiber MTP connector on one end and three 8-fiber MTP connectors on the other end. As shown in the following figure, a 120G CXP transceiver is plugged into the 100G CFP interface on the switch on the one side, while three 40G QSFP+ transceivers are plugged into the 40G QSFP+ interfaces on the switch on the other side. Then the 1×3 MTP conversion cable connects the 120G CXP transceiver with the three 40G QSFP+ transceivers—the 24-fiber MTP connector terminated at the cable is directly plugged into the CXP transceiver, while the three 8-fiber MTP connectors are plugged into the three QSFP+ transceivers. In this way, 40G to 100G migration can be realized smoothly.

2×3 MTP Conversion Cable

This type of MTP conversion cable can be used for 10G to 40G or 40G to 40G connection. It is structured with two 12-fiber MTP connectors on one end and three 8-fiber MTP connectors on the other end. For 10G to 40G connection, MTP fiber optic cassette is also needed. As shown in the following figure, three 40G QSFP+ transceivers are plugged into the 40G QSFP+ interface on the switch on the one side, while twelve 10G SFP+ transceivers are plugged into the 10G SFP+ interfaces on the switch on the other side. Then the three 8-fiber MTP connectors terminated at 2×3 MTP conversion cable are directly plugged into the three 40G QSFP+ transceivers, while the two 12-fiber MTP connectors are plugged into the MTP 12 fiber adapters mounted at the rear of the MTP fiber optic cassette. With one end of twelve duplex LC patch cables plugged into the LC adapters on the front side of the cassette and the other end of the twelve cables plugged into twelve 10G SFP+ transceiver, the 10G to 40G connection is accomplished.

For 40G to 40G connection, we can use a MTP adapter panel. From the figure below, we can find that the connections on both sides are symmetrical. The three 8-fiber MTP connectors at the end of 2×3 MTP conversion cable are directly plugged into the three 40G QSFP+ transceivers, then into 40G QSFP+ interfaces on the switch. And the two 12-fiber MTP connectors of both two MTP conversion cables are plugged into MTP 12 fiber adapters on the MTP adapter panel.

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.

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 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.
