Description

GECEN ORH-1020A – Micro Optical Receiver 1260~1600nm, CATV with AGC, SC/APC 
 
Overview:
The ORH-1020A optical receiver converts optical signal coming via passive optical network from the optical transmitter into electrical CATV signals. These CATV signals are terrestrial DVB-T, DAB and FM broadcasts.

The ORH-1020A optical receiver can receive laser wavelengths between 1260~1600nm. It features high sensitivity (-7~+2 dBm), thus it can be used at the end of comparatively long optical link. The minimum RF output level of 80 dBμV is suitable for distribution of the channels via passive components throughout an apartment, office or house.

The product is intended for indoor usage only.

Features:
● Micro optical receiver of CATV signal
● Smaller size and easier installation
● Designed for FTTH networks
● Robust aluminum die-cast housing with high screening efficiency, nickel-plated
● Using GaAs amplifier active devices
● Excellent linearity and flatness
● Wide range of optical input power
● Singlemode fiber high return loss
● Ultra low noise technology
● RF automatic gain control (AGC) function embedded in MCU
● Red-LED for power indication
● Double color LED for optical power indication:
– Non-lighted: <-7dBm (too low power)
– Green: -7dBm < +2dBm (sufficient power)
– Red: > +2dBm (overload power)
● Wall mounting
● Connectors:
– RF output – type F
– DC entry – type F
– Optical input – SC/APC
– Screw terminal block for ground
