FTTP/FTTH Optical Node
![OFS-R3201B]( "OFS-R3201B")
Description
OFS-R3201B optical node can be used for CATV networks, digital networks, and telecommunications networks. Especially for fiber to the building, the output port directly over-ride the user's FTTx network.
The received optical power range of OFS-R3201B is from -9dBm to +3 dBm, optical AGC range is from -8 to +2 dBm, within this range, the dual-port independent of the output of each RF level up to 108dBuV. -1 DBm received CNR greater than 51dB.
Feature
1, 47-870/1000MHz operating bandwidth
2. Meet the national standard SNMP network management requirements, support the setup, management of remote network management operation or local key operation on the receiver.
3, improve the surge suppression circuit to improve the ability of anti-lightning and prevention of the impact of the surge.
4, -8 to +2 dBm stable and reliable optical AGC function, received optical power range -9 to +3 dBm.
5, the use of imported low-noise, high-performance, highly reliable GaAs chip, greatly improved the C / N and nonlinear distortion characteristics, while significantly reducing the overall power consumption, Power consumption less than 8W.
6, strict reliability tests, more than 100,000 hours MTBF.
7, the selection of the response is greater than 0.9A / W high-light detector.,
8.Digital real-time display of various operating parameters, the ESC attenuation (A), balanced (E), Through external 3G certified high-quality opening adapter
