12-fiber MTP and 24-fiber MTP cables are widely used in 40G and 100G high density cabling. However, in many cases, not all the fibers are used. For instance, to connect a 40G-SR4 QSFP+ module, we usually use a 12-fiber MTP cable with only 8 fibers in use. If you have built a 24-fiber cabling system, you can use MTP conversion cable to make full use of the existing optical fibers.
MTP Conversion Cable
Unlike MTP-LC harness cable, MTP conversion cables are terminated with MTP connectors on both ends. However, the MTP connectors on each end are different in fiber counts and types. MTP conversion cable can provide more possibilities for the existing 24-fiber cabling system. The following are the most commonly used MTP conversion cable:
|1*2 MTP conversion cable||2*3 MTP conversion cable||1*3 MTP conversion cable|
|24-Fiber MTP to 2*12-Fiber MTP||2*12-Fiber MTP to 3*8-Fiber MTP||24-Fiber MTP to 3*8-Fiber MTP|
MTP Conversion Cable Application
The total fiber counts of the above three MTP conversion cables are all 24. But the can provide different connections in multi-fiber cabling system. The following will introduce the applications of these cables.
1*2 MTP Conversion Cable
This MTP conversion cable has one end terminated with a 24-fiber MTP connector and the other end terminated with two 12-fiber MTP connector. With this cable, two 12-fiber optical singles can be transferred on to a 24-fiber cable for transmission. In multimode cabling system, the optical signals of two 40G-SR4 QSFP+ modules can be transmitted over a single 24-fiber MTP cable as shown in the following picture.
1*3 MTP Conversion Cable
1*3 MTP conversion cable has one 24-fiber MTP connector terminated on one end and three 8-fiber MTP connector one the other end. The 8-fiber MTP connectors can be connected to 40G-SR4 QSFP+ modules. This MTP conversion cable utilizes 100% of the existing 24 optical fibers. Each fiber can be used to transmit 10G optical data. Three 40G dual-way transmissions can be achieved on the existing 24-fiber MTP cable. It can also be used to breakout the 120G CXP module signals into three 40G QSFP+ SR4 optical signals.
2*3 MTP Conversion Cable
2*3 MTP conversion cable is terminated with two 12-fiber MTP connectors and three 8-fiber MTP connectors. This MTP conversion cable allows three 40G-SR4 optical signal transmit on the existing two 12-fiber MTP trunk cables as shown in the following. If you have built a 12-fiber MTP cabling system. This 2*3 MTP conversion cable can increase about 30% capacity of the existing network.
MTP Conversion Cable Selection
MTP conversion cables are designed to provide a more flexible multi-fiber cabling system based on MTP products. It can largely increase the capacity of the existing 12-fiber and 24-fiber MTP network. The above mentioned MTP conversion cable in different fiber types and cable lengths.
