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 Televés include OLC (Optical Level Control), a system capable of preserving the radio-frequency signal regardless of the optical input

Highlights:

  • 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

Main features:

  • 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
