Nowadays, data communication technology has developed rapidly. To achieve high speed transmission, it is very common to see complex cabling system in data center, which may even include thousands of fibers. Under such circumstances, saving space in data center is a critical issue. Therefore, fiber optic components or cabling solutions which are characterized by high density will gain the popularity among data center managers. MTP component is such one that can satisfy the requirement. And this article is going to introduce FHX ultra MTP/MPO cassettes and their applications in data center.
MTP/MPO cassette is widely used for high-density cabling in data centers. It is pre-terminated and pre-tested enclosed unit which can provide secure transition between MTP and LC, SC or MTP discrete connectors. And it is usually structured with LC, SC or MTP adapters on the front side of the cassette and MTP adapters at the rear of the cassette. FHX Ultra MTP/MPO cassette has three types: FHX ultra 8F MTP-LC cassette, FHX 12F MTP-LC cassette and FHX MTP conversion module. Here is a figure for you to have a better understanding of these three types of MTP cassettes.
For application, MTP cassette can be easily found in 10G, 40G and 100G network applications in data center.
Since both FHX ultra 8F MTP-LC cassette and FHX 12F MTP-LC cassette serve to realize the transition from small diameter ribbon cables terminated with MTP connector(s) to the more common LC interfaces used on the transceiver terminal equipment, this part will take FHX ultra 8F MTP-LC cassette as an example. The FHX ultra 8F MTP-LC cassette is structured with four LC duplex (8-fiber) adapters on the front side of the cassette and one 12-fiber MTP adapter at the rear of the cassette, and it is often used for 10G to 40G connection. As the following figure shows, we can also add FHX ultra enclosure and FHX MTP adapter panel to the cabling solution. From the left to the right, four 10G SFP+ transceivers are plugged into four 10G ports on the 10G switch. Then they are connected to LC adapters on the FHX ultra 8F MTP-LC cassette through four LC duplex patch cables. The cassette is installed in the FHX ultra enclosure. One MTP trunk cable connects two MTP adapters respectively on the rear of the cassette and MTP adapter panel. Finally, the 40G QSFP+ transceiver on the 40G switch is connected with MTP adapter on MTP adapter panel through another MTP trunk cable. In this application, 100% fiber utilization is realized. What’s more, the 1U fiber enclosure can house 18 x 8F FHX cassettes or 12 x 12F FHX cassettes, with the total fiber capacity up to 144 fibers for LC interface, greatly saving cabling density.
The FHX MTP conversion module has several kinds, this part will take 3x MTP-8 to 2x MTP-12 (24-fiber) conversion module as an example. This kind of FHX MTP conversion module is structured with three 8-fiber MTP adapters on the front side of the module and two 12-fiber MTP adapters at the rear of the module. We can use FHX ultra enclosure to hold MTP conversion module. The following figure shows the cabling solution for 120G to 120G connection. Three 40G QSFP+ transceivers are respectively plugged into 40G ports on three 40G switches on both sides. Then the three 40G QSFP+ transceivers are connected with three 8-fiber MTP adapters on the front side of the module through three MTP trunk cables. Finally, two 12-fiber MTP adapters at the rear of two respectively modules are connected through two MTP trunk cables. This cabling solution utilize Based-8 MTP cabling system and achieves 100% fiber utilization. With the use of 1U FHX ultra enclosure, twelve 3x MTP-8 to 2x MTP-12 conversion module can be used in this cabling solution, which creates a 33% spacing-saving upgrading path.
The FHX ultra MTP/MPO cassettes can not only meet the need for saving space in data center cabling, but also realize 100% fiber utilization during the cabling. With superior best-in-class features, FHX ultra MTP/MPO cassettes can offer cost-effective, simple 10G to 40G, 40G to 40G, 40G to 100G or 120G to 120G cabling solutions and ensures high performance at the same time.
