Optic Node Switcher

ONS-2M-1P-860

Catvision’s Optic Node Switcher is an important equipment in optic fiber transmission system, designed to ensure reliable and uninterrupted RF output in HFC Networks.

Optic Node Switcher is mainly used for auto switching between primary optic signal, back-up optic signal and local headend RF signal , so as to automatically switch to backup optic input signal, if the primary optic input signal is absent or it’s level is lower. In case, both the optic signals are absent, then the Optic Node Switcher shall automatically power ON the local headend system and its RF signal will be distributed in the network.
