Detailed Product Description

FEATURES:

1. high-sensitivity optical detector

2. low-noise DFB laser for return

3. low-noise PHILIPS push-pull amplifier module at forward stage and PHILIPS power-doubled amplifier at the backward stage( designed according to users requirements)

4. With plug-in combining filter, fixed attenuator, on-line test port, to make the modulation more convenient

5. With four high-level outputs and low distortion

6. with one forward receiving module and one reverse transmitting module

7. modularized design for the internal devices for easier upgrading and maintaining

8. High-reliability switch power supply, strict anti-thunder system

9. Inset excellent channel separation circuit to reduce to the mini rate the cross talk of the forward signal, backward signal and the net management signal

10. Net management responder can be installed to have the intelligent net management function

11. Water-proof aluminum-cast shell and nice heat loss function
