UV-ON-4H is a broadband optical node designed for HFC networks. It can be configured 2 forward path optical receiver modules, 2 return path optical transmitter modules, 1 NMS transponder module and 2 switching power supply modules at most. It is adopts advanced optical AGC technology, with LED segment display function, the forward path output signal ≥116dBμV. The output level and output slope both adopt the electric control circuit

* 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 116dBμv.
* 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.
* Full electric adjust attenuation and equilibrium control circuit, and achieve remote
operation by NMS.
* Reserved C-CMTS forward path and return path RF interface, support DOCSIS EOC
networking scheme.
