7. Optical input (fc/apc or sc/apc adapter) 8. Rf output 9. Power in block diagram 1. Gain adjuster a variable attenuator to control the output level. 2. Plug-in equalizer the equalizer board is for customer’s option. It is used to establish a slope output from the receiver for distribution of the s...
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 conne...
Table 2. Also, you can test the output level by using a field-strength meter. Table 2 test point voltage vs optical input power test point voltage (vc) optical input power (dbm) output level 2.00 0.0 110 1.58 -1.0 108 1.26 -2.0 106 1.00 -3.0 104 0.80 -4.0 102 0.64 -5.0 100 0.50 -6.0 98 -7.0 96 -8.0 ...
(4) considering the different demand of systems, we can supply a series of pre-slope pin-board. (see table 3) (5) the power indicating lamp is lit if the optical input level is low than –15dbm. Please check the working condition of the optical link. (i.E., fiber connection, the output level of the t...
