INSTALLATION AND ADJUSTMENT
To properly install the receiver, please remember to look through the User’s Manual before use, and
perform the following steps.
Invisible optical beam come out from the end of the optical connector, permanent damage would
happen to eyes if see it directly.
1. Fiber Connection
Splice the fiber service cable to the transmitting fiber before node installation. Fusion splicing is
recommended since it has low insertion loss and is the most reliable method. The splicing should be
done by experienced technicians.
Carefully remove the protective cap from the end of the FC/APC or SC/APC connector, clean the end
with a lint free tissue moistened with alcohol, then insert the connector into the FC/APC or SC/APC
adapter in the rear panel, and tighten the connector securely.
2. Power Connection
Put the plug into the power receptacle, and the Power Indicating Lamp will be lit.
3. Receiver/Link Performance Testing & Adjusting
(1). Measure the voltage at the optical input power test point with a voltmeter. The voltage at this test
point represents the optical input power. Take note of this voltage for future reference. Then, using
Table 2 to find the corresponding optical input power. Also, you can test the optical input power by
using a Optical Power Meter.
(2).The optical input power can be between 0dBm and -15dBm. A signal level greater than 0dBm must
be attenuated to meet with the distortion target, while a level lower than -15dBm may result in an
unacceptable C/N parameter.
(3). Output Level
The output of the receiver is a function of the optical input power and the modulation of the transmitter
is generally set at 3.5%/CH. The optical input power vs the minimum RF output level is listed in
Table 2.
