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.
