Page 4: Block Diagram
The optical power test point inside the receiver is scaled at 2 Volts per million watt and provides an indication of received optical signal power. The expected DC voltage at this test point should between 0.5V and 2.0V. Optical Receiver VL2510... -
Page 5: Installation And Adjustment
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. Optical Receiver VL2510... - Page 6 The Optical Power Monitoring Lamp is lit if the Input Power below –15dBm. If the output level needs to be changed, open the machine and adjust the rheostat W1. In return path of the fiber system, the output level of VL2510 is 100dBµV provided that the optical input level is –5dBm. (See Table 2) Table 3...
- Page 7 (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 Transmitter, etc.)
