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.

About Rack-Mounted Fiber Cassette

In most applications of data center, rack-mounted fiber cassette is often used. Since most rack-mounted network devices are 19 inches, the width of rack-mounted fiber cassettes are standard 19 inches, but the height has a variety of sizes. We use “RU” for the height of rack-mounted fiber cassette and 1RU is 1.75 inches. The height of rack-mounted fiber cassette can be 1 RU, 2 RU, 3 RU, 4 RU and so on(shown in the following figure).

Different Types of Fiber Cassettes

In order to meet different needs of data center, there are various types of fiber cassettes which are classified according to different aspects.

Using Way

1RU rack-mounted fiber cassette is commonly used in data center. According to different using ways, 1RU rack-mounted fiber cassettes are designed for three types: Clamshell fiber cassette, sliding fiber cassette and rotational fiber cassette. Clamshell fiber cassette is the earliest type of fiber cassette which is low in price but not easy to use. Sliding and rotational fiber cassette are slightly high in price, but they can make it easy to install and maintain the cables inside the cassette. We just need to pull or spin out the tray of cassette for easily handling the fiber, without having to removing the fiber cassette from the rack first.

Front Panel’s Design

As we all know that fiber adapter is an essential component of a fiber cassette and it is usually installed on the front panel. The number of fiber adapter is directly related to the port density of fiber cassette. In a word, the front panel of fiber cassette has two types: fixed and not fixed.

The width of front panel fixed fiber cassette is standard 19 inches and the number of fiber adapter on it is usually fixed.

Front Panel Fixed Fiber Cassette

While front panel not fixed fiber cassette can install 3 or even 5 detachable fiber adapter panels, and now it is widely favored for high-density cabling, plug and play, flexible cable management.

Front Panel Not Fixed Fiber Cassette

Fiber Termination

Pigtail fusion splicing and pre-termination are two basic methods of fiber termination. According to this, rack-mounted fiber cassette has two different designs: pigtail fusion splicing fiber cassette and pre-termination fiber cassette. Inside pigtail fusion splicing fiber cassette, there is a fiber splicing tray which is used for the management and placement of spliced fibers on working site; while inside pre-termination fiber cassette, there is only spools for managing the fiber optic cables. Obviously, pre-termination fiber cassette eliminates the step of fiber termination on working site, greatly saving installation time and labor costs.

Accessory Inside Fiber Cassette

Usually, the front panel of 1RU sliding fiber cassette can install four fiber adapter panels and install one or multiple fiber splicing trays inside cassette. Fiber cassette with this design is suitable for application which needs to splice fibers on working site and can provide effective protection for fiber splicing point.

Fiber Cassette With Splicing Trays Inside

There are four fiber adapter panels on front panel of fiber cassette, and inside cassette, there are two spools. It is a kind of pre-termination fiber cassette which can greatly save installation time and labor costs.

Fiber Cassette With Spools Inside

1RU sliding fiber cassette can install at most four MTP cassettes, realizing the smooth transfer from MTP backbone cabling to LC cabling system. It is the ideal solution for 10 G to 40 G/100 G high-density cabling.
