FHX MTP/MPO-12 Cassettes vs. FHX MTP/MPO-8 Cassettes

With the increase of network throughput, 40GbE network has become widespread and 100GbE is also extensively deployed. Under this circumstance, traditional LC cabling can not meet the high speed and high density demand of the data center. Therefore, achieving higher transmission rates and finding suitable solutions for high density cabling become the top priority. The emergence of FHX MTP/MPO cassette is a quite good news to high density cabling, which not only serves as a perfect solution for high performance data transmission but also saves space in data center. Commonly used FHX MTP/MPO cassettes are FHX MTP-12 cassettes and FHX MTP-8 cassettes. This article will cover what are they and difference between them.


Overview of FHX MTP/MPO Cassettes

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 MTP/MPO cassette has three types: FHX MTP/MPO-12 cassette, FHX MTP/MPO-8 cassette and FHX MTP/MPO conversion module. Commonly used are the former ones.

As both Base-8 and Base-12 play an important role on the basis of MTP system, some network designers may ask “Will one cabling solution fit all applications? They don’t look much different?” Although they have the same function, and the only difference is 12 fibers vs 8 fibers, one cabling solution can’t fit all applications.

We know that Base-12 makes use of fiber optical links based on increments of 12 fibers and 12-fiber MTP fiber optic connector is common used. However, there is a problem when using Base-12 cabling solution—four fibers for transmit and four fibers for receive, leaving four fibers unused per connection. While Base-8 can be a more cost-effective option for end-to-end MPO to MPO channels and architectures. Deploying Base-8 connectivity in duplex architectures for 10GBASE-SR and 25GBASE-SR will save 4% to 5% for data center managers, but if you are running groups of 6-ports, Base-8 may result in a significant cost increase.

Network built with 8-fiber MTP system can transmit the same data with less cost and higher density compared with 12-fiber MTP system. All fiber will be 100% utilized in base-8 MTP products. It could be a cost-effect solution for both 40G to 40G transmission and 40G to 10G transmission. For more MTP/MPO base 8 vs base 12 link, you can read: 8-Fiber MTP VS. 12-Fiber MTP Cables


There are a variety of advantages of FHX MPO/MTP cassette modules. With the easy-installed design, it can greatly reduce the labor cost and save more space and time. In addition, it is easier for management and maintenance and has lower security risk. It satisfies the demands for high optical port density and system interoperability. Thus, it is more and more popular among users. MPO/MTP cassette modules can be used in both lower fiber count break out applications (e.g., server cabinets) and high fiber count interconnects by mounting in chassis. It is an ideal solution for interconnection or cross-connection in telecommunications networks, WDM applications, data center cabling, backbone cabling and 40/100G communication network.
