WR-1004N-MLD-GD outdoor optical node can be configured 2 forward path optical receiver modules, 2 return path optical transmitter modules, 1 Ethernet transponder module and 2 switching power supply modules at most. Adopts advanced optical AGC technology, the adjustment of output level and output slope both adopt fixed inserter. Add LED nixie tube display function, can output 4-way forward path signal (≥108dBμV) at most.
* Forward path optical receiving part adopts advanced optical AGC technology, the input optical power range extended to -8～+2dBm.
* Forward path optical receiving part: RF operating bandwidth extended to 1GHz, each way maximum output level up to 114dBμv.
* The attenuation and equilibrium control circuit adopts fixed inserter, and achieve remote monitoring by NMS.
* RF amplifier part adopts quick plug modular design, can quickly replace RF amplifier module without dismantling the RF cable connector.
* Built-in perfect condition monitoring circuit, and support Ethernet transponder.
* Built-in tri-state gate switch circuit in the return path. Three states passthrough, -6dB and OFF can be remote set by network management responder.
* Reserved C-CMTS forward path and return path RF interface, support DOCSIS EOC networking scheme.
