FiberKom mini-optical node equipped with Return Path transmitter and OLC technology (2 fibers) 1200...1600 nm, Return: 1310 nm, Po 3 dBm

Mini-optical node to act as a bridge between coaxial technology and optical networks. Transforms the optical signal (1200 nm-1600 nm) on the main network into a coaxial signal (54 MHz-1006 MHz) that travels to the user's modem.
It also transforms the coaxial modem's signal (5 MHz-42MHz) into an optical signal for the operator's headend, thanks to the the Return Path transmitter on the 1310 nm window with 3 dBm optical power.
Uses two fibers: one for the forward channel and the other for the Return Path.
Perfect for installations where the DOCSIS protocol is used for the bidirectional distribution of data, and the DVB-C standard is used for television signals.
Equipped with OLC technology.
Perfect for RF Overlay and FTTB applications.

  • The OLC (Optical Level Control) technology automatically adjusts the parameters to achieve a constant output level, irrespective of the channel load
  • Equipped with attenuation controls
  • High output voltage (RF amplification) and enhanced C/N
  • Wide reception optical range
  • Very low power consumption

Main features
  • DOCSIS compatible
  • Two operation modes:

    1. CW (Continuous Wave) in which the laser transmits continuously; useful in applications where the Return Path is attenuated (FTTB).

    2. RFoG (RF over Glass) where the laser only transmits when there are packets to be transmitted; it is therefore recommended for installations with minimal attenuation on the Return Path (FTTH).

  • SC/APC optical connectors, and F-type connectors for RF
  • Local powering
