mpo jumper and mpo fiber coupler,one:comprehensive explanation of MPO jumper:
Readme of MPO fiber optic jumper:
MPO fiber optic jumper:MPO(Multi-fiberPushOn)connector is one of the MT series connectors.The ferrules of the MT series use two guide holes and guide pins with a diameter of 0.7mm on the left and right sides of the ferrule end face(also known as PIN needle)for precise connection.The compact design of the MPO connector makes the MPO jumper more cores and smaller in size.MPO jumpers are widely used in the wiring process that requires high-density integrated optical fiber line environments,FTTX and 40/100GSFP,SFP+and other transceiver modules or internal and external connection applications of equipment.
Classification and specifications of MPO fiber optic jumpers
MPO fiber optic jumpers are divided into transfer type and non-transfer type:transfer MPO jumpers include ribbon MPO jumpers,beam MPO jumpers,and mPO jumpers fanned out through splitters(round or square),generally 2~24-core 0.9 or 2.0 fiber optic cable branches can be transferred.The type of connector is specified by the customer,and FC,LC,SC,ST and other types can be selected.The total length of the MPO jumper or branch length and other requirements can be selected by the customer.
Non-transfer jumper:MPO optical fiber jumper,MPO transfer jumper,MTP type,MTP 10 Gigabit jumper,multi-mode 10 Gigabit jumper,MPO jumper with splitter and other forms of MPO jumper products.
All of the above are in line with Telcordia-GR-326,IEC standards and Rohs requirements.

Analysis of the principle of two fiber couplers
The coupler uses light as the medium to transmit electrical signals.It has a good isolation effect on input and output electrical signals.
Composition of fiber optic coupler:light emission,light reception and signal amplification.Since the input end of the optocoupler is a low-resistance element that operates in a current mode,it has a strong common-mode rejection capability.
The light-emitting source and the light-receiving device are assembled in the same airtight housing,and are separated from each other by transparent insulators.
The pin of the light source is the input end,and the pin of the light receiver is the output end.The common light source is a light-emitting diode,and the light receiver is a photodiode,phototransistor,etc.
The working principle of the fiber coupler:
Optical fiber coupler is a device for detachable(movable)connection between optical fiber and optical fiber.It precisely butts the two end faces of optical fiber so that the optical energy output by the transmitting optical fiber can be coupled into the receiving optical fiber to the maximum extent.And make it intervene in the optical link so as to minimize the impact on the system.
The scope of application of fiber optic couplers:
1.Telecommunication network:convert optical signals into electrical signals.
2.Cable TV network:Coupling multi-mode signals into single-mode signals.
3.User loop system:Make the cross-sectional fiber holes of the two fiber optic connectors conduct.
4.Regional network:make two groups of optical signals communicate with each other.Author:Clan communication https://www.bilibili.com/read/cv21564558?from=search&spm_id_from=333.337.0.0 Source:bilibili
