MPO connector is one of the MT series connectors, which is a multi-core and multi-channel plug-in connector. The MT series plug-in adopts two 0.7mm diameter pilot holes on the end face of the plug-in core to precisely connect the pilot pin (also called pin).
Compared with other connectors, MPO connector is characterized by compact design and many jumper cores. MPO connectors are the same size as SC connectors, but can hold 12 or 24 optical fibers, so MPO can greatly save cabinet cabling space. At present, the common MPO connector is 12, 24 core MPO jumper.
MPO optical fiber connector includes optical fiber, sheath, coupling component, metal ring, pin, dust cap, etc., and the pin part is divided into male and female. The male connector has two pins, while the female connector does not. The connection between MPO connectors is precisely aligned by pin pins.
Generally, an optical link needs two optical fibers to complete the whole transmission process. Polarity is the interconnection matching between TX and Rx at both ends of the optical link.
MPO polarity classification:
Type A (straight through): the 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 directions at both ends are opposite. Key up corresponds to key down.
Type B (interleaved): 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 directions at both ends are the same, that is, key up corresponds to key up, and key down corresponds to key down.
Compared with other optical fiber connectors, MPO connector has the characteristics of small size, high precision, high density, etc. its appearance greatly improves the popularity of optical network and reduces the production cost. Therefore, MPO jumpers are widely used in the high-density integrated optical fiber line environment, such as FTTX, 40 / 100gsfp, SFP + and other transceiver modules or equipment internal and external connection applications.
