For the increasing demand of high-speed and high-capacity optical communication system, MTP / MPO optical fiber connector and optical fiber jumper are ideal schemes to meet the high-density wiring requirements of data center. Due to their advantages of large number of cores, small volume and high transmission rate.
MPO Fiber optic patch cable is composed of MPO connector and optical fiber cable. MPO connector types are distinguished according to IEC 61754-7 by several factors: number of cores (count number of optical fiber count), male female head (male female), polarity (key), polishing type (PC or APC).
Which the fiber core numbers of MPO?
At present, the factory termination components of MPO connectors can accommodate 6 to 144 optical fibers, of which 12 and 24 core MPO connectors are more common. According to IEC-61754-7 and EIA / TIA-604-5 (FOCIS 5), 12 Fibers optical fibers are usually arranged in one column, which can support one or more columns of optical fibers in the same MPO connector. According to the number of cores in the connector, they are divided into one column (12 cores) and multiple columns (24 cores or above). The 40G MPO-MPO Fiber optic patch cable generally adopts 12 core MPO multimode plug-in; the 100G MPO-MPO Fiber optic patch cable generally adopts 24 core MPO plug-in. At present, there are 16 single row optical fiber array types in the market, which can be divided into multiple columns to form 32 cores or above. The 16 / 32 Fibers MPO optical fiber connector will become the best solution for low delay and ultra-high speed transmission of the next generation 400G network.
Male and female of MPO Connector
MPO optic fiber connector includes optical fiber, sheath, coupling assembly, metal ring, pin (pin pin), dust cap, etc. the pin part is divided into male and female. The male connector has two pins, while the female connector does not pins. The connection between MPO connectors is accurately aligned through pins, and the two MPO connectors connected to each other must be one male and one female.
MPO polarity:
Type A: the fiber cores at both ends of the jumper are arranged in the same position, that is 1 at one end corresponds to 1 at the other end, and 12 at one end corresponds to 12 at the other end. The key orientation at both ends is opposite, and key up corresponds to key down.
Type B (interleaved type): the fiber cores at both ends of the jumper are arranged in opposite positions, that is 1 at one end corresponds to 12 at the other end, and 12 at one end corresponds to 1 at the other end. The key orientation at both ends is the same, that is, key up corresponds to key up, and key down corresponds to key down.
Type C (paired interleaved type): the MPO jumper of type C is a pair of adjacent core positions crossing, that is core 1 at one end corresponds to 2 at the other end, and core 12 at one end corresponds to 11 at the other end. The key orientation at both ends is also opposite, and key up corresponds to key down.
What is MTP?
MTP is “multi fiber termination push on”, which is developed by US Conec. It improves attenuation and Reflection on the standard MPO connector and has high overall performance. Externally, there is almost no obvious difference between MPO and MTP connectors. In fact, they are completely compatible and match each other.
MPO / MTP optical fiber connector and optical fiber jumper provide a simple and easy to manage optical fiber cabling solution. It is widely used in FTTH and data centers that need high-density integrated optical fiber lines. It is likely to become a hot demand product for 5G data center construction in the future.
