fiber nodes for HFC/RFoG & RF Overlay
The LR 2x series of fiber nodes are optical nodes for HFC, RFoG or RF Overlay applications.
They can be operated in RFoG (burst-mode) and HFC (continuous wave) mode.
High RF output level of 117 dBµV for
coaxial distribution of FTTC or FTTB signals
DOCSIS-3.1-compliant frequency range:
Downstream up to 1.2 GHz, Upstream up
to 200 MHz
Pluggable diplexers enable migration
towards DOCSIS 3.1 upstream
Pluggable output splitters / taps for flexible
configuration of the two RF outputs
