The coaxial backbones of? the operator networks are being replaced with optical fibre lines. The optical network ends where the subscriber’s coaxial network is serviced. These networks that use both transmission media are known as HFC networks (Hybrid Fibre Coaxial).

An element is required to work as an interface between the optical backbone and the coaxial network where both media meet; this device is the Optical Node.

This device transforms the downstream optical signal into a radio-frequency signal; furthermore, it transforms the radio-frequency? signal produced by the cable-modem and/or the? user’s STB (return channel) into an upstream optical signal.

Occasionally, when communication is exclusively downstream, an optical receiver is installed instead of the optical node to transform optical signals into radio-frequency signals.

Optical nodes and receivers from Telev?s include OLC (Optical Level Control), a system capable of preserving the radio-frequency signal regardless of the optical input

Main features
Equipped with OLC (Optical Level Control), which automatically regulates its parameters to provide a constant output level regardless of? the channel load
Configurable return channel with attenuator and equalizer
Forward channel with independent attenuation and equalization adjustment between stages
High output voltage, low power consumption
Perfect for RF Overlay, FTTB and FTTC applications
Parameter values are adjusted using plug-in jumpers at the front of the equipment (equalization, attenuation, etc.)
Test socket
Full bandwidth optical reception
Aluminium-manufactured, the chassis ensures durability in outdoor installations
