Cleaning Guide:
6.1.1)
Fiber Optic jumper
Removal the dust cap of fiber optic connector, pay attention to confirm the optical
connector is a APC surface;
The tips of cleaning fiber optic connector is to use a dedicated and dry cloth without
velveteen (the company 5Kimwipes ®’s fine cloth); In addition, preferably adopt special
microscope (at 100 times, 200 times) to check the cleanliness of fiber optic connector
surface or blemish.
pay attention to maintaining the fiber optic connectors is clean;
fiber optic connectors (flange) is clean;
you can use a dedicated compressed gas to clean the surface of fiber optic connector;
you can remove the dust which is less than 0.2 microns, better without residue;
hold the tank of compressed air from the connector about 6 inches, alignment flange, and
press the nozzle switch shortly times, so you can clean the connector completely;
if there is no dedicated compressed air, the 2.5 mm cotton swab for cleaning can also be
used to clean the optical transmitter connectors, or remove the flange and clean the other
side of the optical fiber jumper connector directly ;
Note: When handling fiber optic connectors must be very careful to avoid damage.
6.1.2)
using the optical fiber jumper to connect the output of optical transmitter to the optical
power meter;
6.1.3)
Using the optical power meter to check the output of the transmitter optical power is
within normal limits;
7 Other notes
7.1)
The machine should have a good grounding, grounding resistance should be smaller
than 4Ω. According to international standards, 220Vac line adopt three-wire system, the midline is
grounding wire.
7.2)
The machine should be set up in a anti-hot, anti-cold, anti-wet environment, so as to
avoid excessive temperature and humidity affect the use life of machine.
7.3)
The machine adopts high-performance, highly reliable switching power supply with
constant voltage and over-current protection. In the right of switching power supply
,
there is 1A
imported fuse that can be work at 85Vac ~ 265Vac electrical line.
7.4)
To ensure the optical return loss ≥ 45dB, this machine’s optical connectors adopt SC /
APC& SC/PC.The connector should be installed to keep clean. You should use ethanol and
defatted cotton wool to wipe after plug repeatedly.
7.5)
Once the laser transmitter enter the work state, because the light signal input(pump light
input) is quite high light output for pump light, the eye cannot look directly at the light input from
the back panel of the machine in order to avoid the laser beam burning the human eye retina.
