5.Operation explanation
(1) Select standard jumper according to the jumper to be tested. If the tested jumper is PC end, select the jumper APC-PC; If the tested jumper is APC end, select the jumper APC-APC.
(2) Zero the return loss of optical channels before the measurement. Press Laser key to switch wave length of light source, connect APC end (say starting end) of the jumper to light source output port, wind the other end (the closing end) of the jumper using the winding bar, the moment the optical power value of the return loss channel should be -60dBm to -70dBm, then press Zero. To measure double wave length, press Laser key to switch the wave length of light source, then press Zero.
(3) Identify the return loss of optical channel before measurement. Release the winded jumper and make the jumper extend up. Insert the end of the jumper into the interface of optical power meter, press Ref. To measure double wave length, press Laser key to switch the wave length of light source, then press Ref.
(4) Zero the return loss of optical channels before the measurement, press dB/w. To measure double wave length, press Laser key to switch the wave length of light source, then press dB/w.
(5) Measure the insertion loss at the end of jumper. Connect the end of jumper and the tested end (starting end) of the jumper to be tested using standard flange, insert the other end (closing end) of the tested jumper into the interface of optical power meter. To measure double wave length, press Laser key to read the insertion loss values of the other wave length.
(6) Measure the return loss at the end of jumper. Wind the jumper near the starting end of the jumper to be tested using the winding bar. The moment the measurement value of return loss appearing in return loss area is return loss value at the starting end of the jumper to be tested. To measure double wave length, press Laser key to read the return loss values of the other wave length.
(7) To proceed to the next test, repeat steps (5), (6).
(8) If you need to replace the standard jumper, repeat the above operations from step (1). If you don’t need to replace the standard jumper, even if the tester has been restarted after power-off, you will only need to repeat steps (5), (6).
Color recognition instruction
Under threshold value setting interface, set reasonable values according to requirements. Green color rbepresents PASS; Red color represents NG
For example. ”plug loss: 0.00dB-0.30dB” implies the value within -0.3dB will show green color, otherwise red color; “return loss: 50dB” implies the value above 50 will show green color, otherwise red color
6.Precautions and maintenance
(1) Forbidden to directly look at laser output interface and optical jumper interface by naked eyes to avoid eyeball and skin hurts
(2) Forbidden to use unmatched optical fiber to connect laser output interface which can damage it and degrade the whole tester performance
(3) Clean all optical fiber interfaces with special tools before use
(4) Minimum length of standard jumper is 1m
(5) Diameter of winding rod is between 3~5 mm. Minimum winding turns is 5
(6) Keep sensor interface clean. Do not use dirty or non-standard adapter or poor polishing interface. Otherwise it will damage sensor interface and sharply degrade the whole tester performance
(7) Suggest to use the same type adapter to minimize errors
(8) Cover all interfaces with dust caps when tester is not used
(9) Carefully handle optical adapter to avoid scratch
(10) Periodically clean sensor. Use special swabs to slightly clean along circle direction
(11) Power off tester and cover optical connector covers if no use. Keep tester in a dry and ventilated place
(12) Keep optical connector clean
(13) Slightly handle tester to avoid collision or drop
(14) Remove power plug if no use with a long time
