The coaxial backbones of the operator networks are being replaced with opti-cal fiber 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 Fiber Coaxial).
A device is required to work as an in-terface 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 (re-turn channel) into an upstream optical signal.
Occasionally, when communication is exclusively downstream, an optical re-ceiver 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 power.
DESCRIPTION
OUTDOOR OPTICAL NODE AND RECEIVER
HIGHLIGHTS
Equipped with OLC (Optical Level Con-trol), which automatically regulates its parameters to provide a constant out-put level regardless of the channel load
Configurable return channel with at-tenuator and equalizer
Forward channel with independent attenuation and equalization adjust-ment between stages
High output voltage, low power con-sumption
Perfect for RF Overlay, FTTx applications
Parameter values are adjusted using plug-in jumpers included (equalization, attenuation, etc.)
Test port
Full bandwidth optical reception
Aluminium chassis ensures durability in outdoor installations
