Description
Technical field
The present invention relates to a kind of MPO of having connector wire jumper test macro, relate 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.
Along with the increasing that has MPO connector wire jumper output, problem related in the production also becomes increasingly conspicuous: fail employing robotization to the optical property that has MPO connector wire jumper and detect and had a strong impact on output and the quality that has MPO connector wire jumper.The optical fiber property of optical patchcord detects and comprises the insertion loss of wire jumper and the detection of return loss, and the quality of these two performance index directly influences the quality of optical patchcord.
At present; Domestic production has the solution that the manufacturer of MPO connector wire jumper adopted and is to use optical branching device to build light path in production test; Connect through optical fiber, manually power detection is carried out on each road that has MPO connector wire jumper, be converted into the insertion loss value through power data again; Can reduce cost very long and very difficult test return loss consuming time though do like this.Concerning one 12 tunnel have the MPO connector wire jumper, at first with an end of wire jumper through a MPO adapter, connect the wire jumper of a MPO-FANOUT, the FANOUT end is connected to the output terminal of optical branching device through 12 fiber adapter, input end connects light source; The other end of wire jumper equally also need connect the wire jumper of a MPO-FANOUT.Operating personnel need measure the optical output power on every road one by one, calculate corresponding insertion loss value again through performance number at last, and manual input computer generates form.Detection efficiency is extremely low like this, has seriously lagged behind to have the production of MPO connector wire jumper.
Design a kind ofly can be convenient to connect, test macro that fast detecting has MPO connector wire jumper optical property is the problem that the technician will solve.
