EH-3000R Node outdoor optical receiver is designed for CATV operators to receive video, audio and data signals over fiber launched from head-end site optical transmitter, and then proceeds O/E convert and RF level amplification to coaxial distribution networks. It’s allowed to install two optical receiver modules for hot-standby purpose and two optical transmitter modules to segment subscribers for bigger service bit rate.
Features
1. Water-proof die-castingaluminum housing
2. 870MHz bandwidth for options
3. Allowed to install two optical receiver modules for hot-standby purpose and two return transmitter modules for subscribers segmentation or hot-standby purpose
4. High RF output power with 4 or 2 RF output ports for options
( 4-port: 103 dBuV/ch@ 12 dB slope, 2-port: 106 dBuV/ch@ 12 dB slope)
5. Unique high linear performance optical module with wide optical input range +2 ~ -3 dBm(Original GaAsamplifier chips adopted)
6. A variety of return transmitter modules for options
(1310nm FP & DFB, 1550nm FP & DFB, CWDM, DWDM transmitter modules with APC function >1mW)
