Features
1) With good quality, high sensitivity optical receiving module (RB) or PIN photodetector(RB-A), higher RF output level, low noise and less nonlinear distortion.
2) Bandwidth: forward (45)87~862MHz/(45)87~750MHz, reverse 5~65MHz (or specified by user).
3) Plug-in diplex filter, several frequency division for selection.
4) Individual input port AC60V power supply.
5) Switching power supply for selection, power-multiplication output.
6) High capability to price ratio

Test Condition
1) Forward part of optical receiver: 10km standard optical fiber, passive optical attenuator and standard optical transmitter composed to test link. Set with 59 PAL-D analog TV channel signal at the range of 45MHz ~ 550MHz under the regular link loss. Transmit QAM modulation digital TV signal at range of 550MHz ~ 862MHz and the digital signal level (8 MHz bandwidth) is lower 10dB than analog signal of carrier level; when the input optical receiver is -2dBm. Please measure the value of C/CTB,/CSO and CNR when output slope is 9dB.
2) Reverse optical transmit part: both link flatness and NPR range are the index of forward optical receive and reverse optical transmit.
