What Do You Know About MPO Fiber Patch Cords?

MPO patch cord, MPO (Multi-fiber Push On) connector is one of the MT series connectors. The ferrules of MT series are connected with holes at 0.7mm diameters and pins. MPO fiber optic cables are divided into transfer type and non-transfer type. There are many types of transfer MPO jumpers, such as ribbon MPO jumpers, beam MPO jumpers, and PO jumper fan-out through the splitter.While defined as an array connector having more than 2 fibers, MPO Connectors are typically available with 8, 12 or 24 fibers for common data center and LAN applications. The type of connector is specified by the customer, FC, LC, SC, ST and other types are optional.The compact design of MPO connector makes the patch cords more cores and smaller in size.

Polarity of MPO Fiber Patch Cords
Generally, an optical link needs two optical fibers to complete the entire transmission process, and the polarity is the interconnection matching between the transmitting end (T) and the receiving end (R) at both ends of the optical fiber link.MPO adapters are divided into two types: A type and B type: (Tx) to the interconnection matching between the receiving end (Rx). Type A: The keyway on one side of the adapter faces up, and the keyway on the other side faces down, so when connecting two MPO connectors, the keyways of the two connectors are on a parallel line. Type B: The key ways on both sides of the adapter face up, so when there are two MPO connectors, the key ways of the two connectors are in a straight line.

Linear Structure of MPO Fiber Patch Cords
Type A (Straight-through Type): The fiber cores at both ends of the patch cords 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, and key up corresponds to key down.

Type B (Reversed Type): The fiber cores at both ends of the fiber patch 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 direction of the keys at both ends is the same, that is, key up corresponds to key up, and key down corresponds to key down.

Type C (Pairs Flipped Tyep): The MPO fiber cable type is the cross of a pair of adjacent fiber cores, that is, the fiber core 1 at one end corresponds to the 2 at the other end, and the fiber core 12 at one end is 11 at the other end. The direction of the key on both ends is also opposite, and the key up corresponds to the key down

Advantages of MPO Fiber Patch Cords
· The small size increases the wiring aperture, thereby greatly improving the wiring density and saving space.
· Modular design, plug and play, saving installation time.
· According to different configuration requirements, the corresponding structure can be selected to meet different wiring requirements.
· It has excellent optical and mechanical properties and low insertion loss in high-speed network environment.
