Summary:

OS-2500 is field bidirectional optical receiving equipments, developed and researched especially for metropolitan area networks; with building block design for the whole structure, and nice flexibility to meet user’s networks requirements; with excellent detecting circuit, networks system which is compatible with HMS standards, and to monitor the networks through network responder.

Features:

1)Adopt the high-sensitivity optical detector at the receiving parts, low-noise DFB laser at the reverse transmitting part, low-noise PHILIPS push-pull amplifier module at forward stage and PHILIPS power-doubled amplifier at the backward stage( designed according to users’ requirements)

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

3)With four high-level outputs and low distortion

4)Four independent forward and reverse channels, which can be modulated independently

5)Modularized design for the internal devices for easier upgrading and maintaining

6)High-reliability switch power supply, strict anti-thunder system, to make sure that the unit can operate stably through a life-long time

7)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

8)Net management responder can be installed to have the intelligent net management function(this function is reserved for users)

9)Structural techniques is compact and reasonable ,with high-stability performance and convenient modulation

10)Water-proof aluminum-cast shell and nice heat loss function can make the unit work in terrible surroundings
