HS-OR31 FTTH Optical Receiver – High Level AGC
HS-OR31 is a compact FTTH CATV optical receiver with AGC constant level output, 47~1002 MHz bandwidth, at least 76 dBuv RF output and a brushed aluminium shell.
Description
Overview
The HS-OR31 FTTH optical receiver is designed for CATV FTTH networks, combining low power consumption, AGC optical constant level output, small volume and high reliability in an aluminium alloy shell.
A GaAs module is used as the RF amplifying module and an optical control AGC circuit is built in, so the output level keeps unchanged across the AGC control range, while the external modular +5VDC power supply keeps installation and debugging convenient.
HS-OR31 Key Features
- Brushed aluminium shell with good heat dispersion
- GaAs RF amplifying module with optical receiving range reaching -23dBm for digital signal and -15dBm for analog signal
- AGC control range +2~-15dBm with the output level kept unchanged
- Low consumption design with ≤2(250mA) total consumption and a high reliability switching power supply with optical inspection circuit
- RF output level of at least 76dBuv with adjustable RF attenuation
- 5 v input port feeding way of external +5VDC power supply
