Description
Technical field
The utility model relates to a kind of MPO of having connector wire jumper test macro, relates in particular to the circuit module of this test macro.
Background technology
Because optical fiber has bandwidth, loss is low, in light weight, antijamming capability is strong, fidelity is high, reliable working performance and characteristics such as with low cost; Replaced the information traditional approach gradually in a plurality of fields such as communication, data transmission, optical fiber communication becomes the data transmission solution of current first-selection.
Though the information transfer capability of the high capacity that optical fiber communication provided, high-speed, long distance has made people in the transmission of information with obtain and obtained a lot of facilities; But people are faster to data rate, transmission quantity requirement bigger, that equipment is more saved the space improves constantly, so more the MPO packaged type of high integration has been born.
The wire jumper that has the MPO connector can better reduce usage space, increase the traffic.Wire jumper that has a MPO connector can integrated 4 cores, the naked fibre of 8 cores or 12 cores, company is also arranged even can produce the wire jumper that has the MPO connector of 24 cores.Suppose that the MPO connector wire jumper that has with 12 cores is a transmitting carrier, a wire jumper that has the MPO connector can transmit 12 circuit-switched data simultaneously, but connection space only accounts for the space of two wire jumper connectors of conventional jumpers connector.On price; Though having the price of MPO connector wire jumper will be far above conventional jumpers; But on the path of transmission data, accounted for incomparable big advantage, shared on the optical fiber of every road when price like this, instead price has bigger price advantage than traditional fiber wire jumper.By above reason, begun the widely-used wire jumper that has the MPO connector in the world as the data transmission solution.China strengthens the data transmission set of paces follow-up oneself also at the step immediately following the world, strengthens the use amount that has MPO connector wire jumper; And as optical patchcord production base the biggest in the world, also can be growing to the production quantity that has MPO connector wire jumper.
