High Efficient HFC Terminal Optical Devices TON6800WII Optical Node For Network
  

Overview 

TON6800WII applies to conventional two-way HFC network and adopt RF PON system adopting forward two path output AGC function is optional, receiving at ＋0～－8dBm,output level≥108dBuV,RF output level changes no more than±0.5dB. Option type reverse optical transmitting component LT2-IFP or LT2-DFB can send data and image at the same time.   

If adopts RF PON (RFoG), the reverse may choose “burst” optical transmitter module to make the reverse transmission as “burst” mode. Adopting the same technology with CMTS TMD  to control the launch of the burst" to achieve at any given time only allowing a TON6800WII keeping communication with CMTS, which greatly improves the intrusive noise.

Open NM transponder option meets national,SCTE HMS and IEC NM standard,which can provide a real-time monitoring of optical node’ s working state,parameter and remote management of network and diagnose, alarm and isolation of network fault.

High efficient and high reliable switching power supply components can turn 40V~60V or ~220V AC power supply into +24V, +5V DC power to supply the devices within the node.
