Product Description

[SOFTEL]4-Way Output CATV Return Optical Receiver



 

Description
4-way output CATV Return optical receiver built in 4-output independent return receiver modules (Philips module ), Easy to use, performance to price ratio high, it has used at large and middle-size city network.
Feature

Each module independent receive and amplify module
19" 1U standard rack installation
Adopts E-O PIN
Adopts PHILIPS push-pull amplify module with high index and good C/N

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
Below part of optical receiver: Standard optical fiber together with transmitter makes the testing circuit. Set with 59 PAL-D analog TV channel signal at range of 45 MHz ~ 550MHz in the fix index loss of circuit. Transmit digital modulation signal at rang of 550MHz~862MHz, the electricity level (8 MHz bandwidth) digital signal is lower 10dB than analog signal of carrier electricity level; The input of optical receiver is 2dBm, output level of RF is 90dBuV with lean beam of 9dB output, measure C/ CTB, C/ CSO, C/ N.
