AON2400C 4-Port 2x2 Optical Node

AON2400C Series 4 port Node is part of ACT Deep Fiber solution, which helps operators expand bandwidth of their existing HFC network while minimizing capital investment. The AON2400C 4 port node is designed with four high outputs up to 108dBuV.

• Forward path optical receiving part adopts advanced optical AGC technology, the input optical power range extended to -8 dBm to +2 dBm.

• Forward path optical receiving part: RF operating bandwidth extended to 1 GHz, each way maximum output level up to 114 dBμV.

• 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, -6 dB 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.
