Description
Technical field
The utility model is related to 2M digital circuit test equipment technical fields, specifically provide a kind of multi-functional 2M tests
Instrument.
Background technology
2M digital circuits refer to providing the link that transmission rate is 2.048Mbits/S to the user, it is that carrying is passed with optical fiber
Defeated backbone network, the all-transparent circuit path that information is transmitted by digital form, by transmission device and transmission two part group of medium
At its international standard point interface is：G.703.
There are two types of the user terminal access ways of 2M digital circuits：One kind make user's terminal technical service optical transmitter and receiver access (8M, 16M,
The optical transmitter and receivers such as 155M, 622M)；Another kind is the access of user terminal computer room HDSL equipment.
All it is to be tested by diode, but because diode is two electric wires now when test 2M digital circuits
And 2M digital circuit interfaces are coaxial cables, so cumbersome during construction testing 2M digital circuits.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of multi-functional 2M testers, convenient to all 2M
The test of circuit.
The utility model is realized in this way a kind of multi-functional 2M testers, including 2M coaxial connectors and light-emitting diodes
Pipe, 2M coaxial connectors are equipped with cable connection end, conductor and shielded layer, two poles of light emitting diode are equipped in cable connection end
It is separately connected conductor and shielded layer, and a resistance in parallel between two poles of light emitting diode.
Further, the resistance value of the resistance is 10 Ω.
Compared with prior art, the utility model has the advantage of：
1, be directly inserted on DDF plates can test 2M digital circuits whether access；
2, small, it can carry；
3, it is convenient for observation, improves working efficiency.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment is described in further detail the utility model：
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model electrical block diagram.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
With reference to figure 1 and Fig. 2, a kind of multi-functional 2M testers, including 2M coaxial connectors 1 and light emitting diode 2,2M is coaxial
Connector 1 is equipped with cable connection end, is equipped with conductor 3 and shielded layer 4 in cable connection end, two poles of light emitting diode connect respectively
Connect conductor 3 and shielded layer 4, and a resistance 5 in parallel between two poles of light emitting diode.The resistance value of the resistance 5 is
10Ω。
When carrying out 2M circuit tests using the utility model, the cable connection end of multi-functional 2M testers is inserted into weldering
In the 2M circuits connected, the core wire in cable is connect with conductor and shielded layer respectively, if welding is good, can be formed access, then be sent out
Optical diode shines, if not being welded, will not form access, light emitting diode does not shine, you can is welded again.
If not parallel resistance 5, since light-emitting diodes tube resistor is excessive, for certain circuits, there is that be not suitable with this novel
The case where, i.e., light emitting diode will not shine, therefore in order to solve this technical problem, on a light emitting diode parallel resistance 5,
Detection circuit resistance 5 is reduced, makes that it is suitable for all 2M circuits.
Claims (2)
