Televes 238081 FIBERKOM 2 FIBER MININODE with RETURN / Fiber HD Converter

Description

Complete range of headend devices to convert CATV and L-Band signals into light for distribution on PON networks. Convert the light to RF at the other end to put it back on a coaxial distribution network (FTTx) with a complete range of receivers and mini-nodes too.
Operating mode upstream:
There are two modes available for upstream operation:
RFoG mode: The laser is switched ON only when a upstream signal is present.
CW mode: The laser is permanently ON.
Forward path:
The output level of the mini-node is kept constant by OLC. The RF output level can be adjusted using the inter stage attenuator.
