FiberKom mini-optical node equipped with Return Path transmitter and OLC technology (1 fibre)
1550 nm, Return: 1610 nm, Po 3 dBm
OLC Technology - (LOCAL Power)
Mini-optical node to act as a bridge between coaxial technology and optical networks. Transforms the optical signal (1550 nm) on the main network into a coaxial signal (105 MHz-1218 MHz) that travels to the user's modem.
It also transforms the coaxial modem's signal (5 MHz-85 MHz) into an optical signal for the operator's headend, thanks to the the Return Path transmitter on the 1610 nm window with 3 dBm optical power.
Uses a single fibre for both the forward and the Return Paths.
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, FTTB, and FTTH applications
HIGHLIGHTS
- 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
- 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
- Either local or remote powering via the output F connector
