HS-OR31B FTTB Optical Receiver – High Level
HS-OR31B is an FTTB optical receiver with AGC constant level output, ≥96~100 dBuv RF output level, 47~1002 MHz bandwidth and ≤4(450mA) power consumption.
Description
Overview
The HS-OR31B FTTB 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.
Its GaAs RF amplifying module and built-in optical control AGC circuit deliver a high level output of at least 96~100 dBuv, while the external modular +5VDC power supply keeps installation and debugging convenient.
HS-OR31B 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 ≤4(450mA) total consumption and a high reliability switching power supply with optical inspection circuit
- High level RF output of at least 96~100 dBuv with adjustable RF attenuation
- 5 v input port feeding way of external +5VDC power supply
