Abstract
The utility model discloses a kind of optical fiber communication telemechanical analog signal tester, the loud speaker that one does not have micropkonic telephone receiver outwards leads to two holding wires in handle other end wire hole, two p-wires are connected with in the outer end of holding wire, two p-wire outer ends are connected on the contact of a test plug, and test plug is provided with inserting handle.The utility model utilizes telephone receiver to make a kind of optical fiber communication telemechanical analog signal tester, and for the break-make of test channel, not only test fast, accurately, and the simple cost of structure is low.
Description
Technical field:
The utility model is a kind of for the whether normal telemechanical analog signal tester of measuring fiber communication port.
Background technology:
State Grid Corporation of China is be main transmission means with optical fiber communication when communication scheduling, for how ensureing that whether optical fiber telecommunications line is unobstructed, the method being used for testing telemechanical analog signal at present has two kinds, one is oscilloscope, another kind is analog signal tester, and these two kinds of instrument Problems existing are that equipment is heavy, expensive, and complicated operation, workload is large.
Summary of the invention:
It is simple that the purpose of this utility model is to provide a kind of structure, and cost is low, is easy to a kind of optical fiber communication telemechanical analog signal tester operated.
The technical solution of the utility model completes as follows, a kind of optical fiber communication telemechanical analog signal tester, it is characterized in that: on the loud speaker that does not have micropkonic telephone receiver, in handle other end wire hole, outwards lead to two holding wires, two p-wires are connected with in the outer end of holding wire, two p-wire outer ends are connected on the contact of a test plug, and test plug is provided with inserting handle.
The utility model utilizes telephone receiver to make a kind of optical fiber communication telemechanical analog signal tester, and for the break-make of test channel, not only test fast, accurately, and the simple cost of structure is low.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
The utility model is the improvement to existing telephone machine receiver, the loud speaker 2 that one does not have micropkonic telephone receiver 1 outwards leads to two holding wires 3 in handle 4 other end wire hole 5, two p-wires 6 are connected with in the outer end of holding wire, two p-wire outer ends are connected on the contact of a test plug 8, and test plug is provided with inserting handle 7.Be used for test time, be connected in voice frequency distributing module, be namely equivalent in parallel with communication line, when analog channel is communicated with, due to the conversion through communication equipment, had electric current by tester, the sound that the loud speaker in receiver can send " titter titter "; When optical fiber telecommunications line disconnects, do not have electric current to pass through, receiver can not sounding.Motion simulation signal divides downstream signal and upward signal, downstream signal is the signal that main website issues substation, and upward signal is the signal that substation feeds back to main website, because the information of two kinds of signals is different, make the size of electric current in circuit also different, the sound that receiver sends is also different.So can detect rapidly that whether communication line is unimpeded, also can distinguish upward signal and downstream signal with this in this way.Because telemechanical analog signal is the 64K/S signal of telecommunication, and identical with the rated voltage in telephone receiver, so receiver can be utilized to access test circuit carry out work.
