Value Line LR 27 2611 Fiber nodes, locally powered

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
