MPO (Multi-fiber Push On) optical fiber jumper is composed of connectors and optical cables, and is a high-density optical fiber transmission jumper. The MPO connector is one of the MT series connectors. It is a multi-core and multi-channel plug-in connector. The ferrule of the MT series adopts two guide holes and guide holes with a diameter of 0.7mm on the left and right sides of the ferrule end face. Needle (also known as PIN needle) for precise connection.
MPO fiber optic jumper
Compared with other connectors, the main features of MPO connectors are compact design and more jumper cores. MPO connectors are the same size as SC connectors, but can accommodate 12 or 24 fibers, so MPO can greatly save cabinet cabling space.
At present, MPO connectors are designed with 8 cores, 12 cores, 24 cores, 48 cores, 72 cores, and 144 cores. Among them, 12 and 24 cores MPO jumpers are more common. 40GMPO-MPO fiber optic jumpers generally use 12-core MPO multimode ferrules; 100GMPO-MPO fiber optic jumpers generally use 24-core MPO ferrules.
MPO fiber optic connectors include optical fibers, sheaths, coupling components, ferrules, pins, dust caps, etc., and the pins are divided into male and female.
The male connector has two PIN pins, while the female connector does not. The connections between MPO connectors are precisely aligned by PIN pins. When the connector is docked, the spring installed at the end of the ferrule will provide a push force to the ferrule to lock it with the adapter. There is a "key" on one side of the connector body, which is divided into "concave and convex", which is used to limit the relative position of the connector, that is, P1, P2, etc. On the body side of the connector there is a mark called a "white dot" that designates the insertion side of the connector.
Compared with other optical fiber connectors, MPO connectors have the characteristics of small size, high precision, and high density. Its appearance has greatly improved the popularity of optical networks and reduced production costs. Therefore, MPO jumpers are widely used in the environment that requires high-density integrated optical fiber lines in the wiring process, such as FTTX and 40/100GSFP, SFP+ and other transceiver modules or internal and external connection applications of equipment.
