Product Description

2-way output CATV optical receiver






Forward optical receive part adopts E-O PIN or WTD (Option) receiving IC. Import PHILIPS (BGY887)amplifier module in pre-RF amplify circuit, import PHILIPS (BGD814) power double amplify module(also adopt GaAs )
Return optical receive part adopts FP or DFB, adopts PHILIPS amplify module (BGY67A) ensure NPR.
Insert dual-filter, insert fix-Equalizer and fix-attenuator or (VAR)
Eight-order optical power indication.
Aluminum waterproof housing, high-capability power switch, anti-thunder system

*The international first-class high-sensitivity optical detector is used in the part of optical receiving. The low-noise DFB laser is used in the part of return optical transmitter.
*The imported push-pull amplifier module with low noise is used in the part of the forestage of RF amplifier. The Imported high-power GaAs module is used in the output stage (It can also be changed if required).
* Two optical receiver modules, the two return optical transmitter modules and two power supply modules can be configured in the building block system modularized design at the most to improve the reliability and security effectively. Two Way Optical Receiver Module is set to automatic switching or manual switching according to the requirement. Switching power supply hot backup module can de switched on line automatically.
* Plug-in duplex filters, plug-in fixed equalizer, plug-in fixed attenuator scientific and reasonable test port makes it easier to debug engineering.
* Both four output ports can output 108 dBμ V high lever signal, each road can be enlarged by a new GaAs power double module independently. The output lever and diagonal of each road are adjustable independently. About 100 end users are drove directly when there are no delayed amplification of preamplifier and user amplification.
* Because of the advanced RF AGC technology, input optical power change from -15dBm to 15dBm, output and nonlinear index remain unchanged.
* Cast aluminium waterproof shell, switching power supply with high reliability and strict anti-lightning system are used to ensure the equipment can work in the field harsh environment for a long time. The perfect multi-channel separation circuit is built in to reduce the interference reduction between forward and backward channel and network management signal to the least degree.
* Perfect status monitoring circuit in which transponder meeting network management standards called <GB / T 20030-2005 HFC Network Equipment Management System Standard> can de disposed is build in it. So remote network management monitoring for equipment is easily implemented. So it can be suitable for front-end management software of other manufacturers.
