Value Line LR 27 6311 Fiber Node, remote-fed
Category : Optical Network Terminations
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
- Device control via bluetooth app or via handset OH 41
- Optional: Remote control compliant to IEC 60728-14 via FSK receiver module
- Compact housing for outdoor deployment (IP66)
- Optical ALC for regulated output levels
