Description
[technical field]
The utility model is related to optical fiber circuit device technical fields, are returned more particularly, to a kind of MPO optical fiber containing attenuation function
Road device.
[background technology]
With the fast development of optical communication technique, the application of optical fiber circuit device is played the role of very important in testing.
Optical fiber circuit device can be used for the signal return in test system or network system, by return path signal, can detect lattice chain
Various potential exceptions, this technology have been commonly used in road, to ensure that the normal of network link provides one kind effectively
Detection mode.Meanwhile optical fiber circuit device can also provide an effective solution scheme, the emissivities of network apparatus test and connect
Receive the requirement of sensitivity, especially telecommunications and data communication.Usual MPO optical fiber attenuations circuit device is by attenuating fiber come real
It is existing, but because the cost of attenuating fiber is relatively high, affect use cost.
[invention content]
Utility model aims to solve existing attenuating fiber deficiencies of high cost, provide a kind of completely new MPO light
Fine surge damping circuit device.
The purpose of this utility model is to be achieved through the following technical solutions：
A kind of MPO optical fiber attenuations circuit device includes the connector matrix for grafting and is connected to the connector base
The optical fiber of body rear end further includes that at least a pair of core and one that patches is used to generate the partition in gap, and the docking lock pin is located at optical fiber
Thang-kng path on, and optical fiber is divided into the first fiber segment and the second fiber segment by the docking lock pin, and being inserted into the partition makes institute
It states and generates gap between the first fiber segment and the second fiber segment, declined behind gap by the first light of first fiber segment
It is kept to the second light of second fiber segment.
It is further improved, the docking lock pin is the MT lock pins of routine.
The utility model utilizes isolation gap Air Gap technologies, can be very good control fade performance, ensures MPO optical fiber
The performance of surge damping circuit device is stablized, and can select the partition of different in width to realize different losses as needed, and to partition
Material without particular/special requirement, it is easy to make, it is easy to operate, it is at low cost.
[description of the drawings]
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the utility model attenuation principle figure.
[specific implementation mode]
In order to keep technological means of the utility model clear, it is new that this practicality is expanded on further below in conjunction with the accompanying drawings
Type.
As shown in Figure 1, the utility model provides a kind of optical fiber circuit device, include the connector matrix for grafting and company
It is connected on the optical fiber of connector matrix rear end, further includes a pair of partition 2 for patching core 1 and one for generating gap, docks lock pin 1
It on the thang-kng path of optical fiber, and docks lock pin 1 and optical fiber is divided into the first fiber segment and the second fiber segment, being inserted into partition 2 makes the
Gap is generated between one fiber segment and the second fiber segment, second is decayed to behind gap by the first light of the first fiber segment
Second light of fiber segment, wherein docking lock pin 1 is conventional MT lock pins.
Attenuation principle figure as shown in Figure 2 is simulated by docking the required loss of lock pin docking generation in practical light path
Generated loss, data that can be in convenient and efficient test optical fiber communication process transmit and receive process in the loss that generates and
Loss.The utility model can select the partition of different in width to realize different losses as needed, and to the material of partition
It is easy to make without particular/special requirement, it is easy to operate, it is at low cost.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
