Mini-optical node that acts as a bridge between coaxial technology and optical networks. Converts the optical signal (1550 nm) in the main network into a coaxial signal (105 MHz-1220 MHz) that arrives at the user’s modem.
Thanks to the return channel transmitter in the 1610 nm window with 3 dBm optical power, the node also converts the signal from the coaxial modem (5 MHz – 65 MHz) into an optical signal for the operator’s headend.
Uses a single optical fibre for forward and return channel.
Ideal for installations using the DOCSIS protocol for bi-directional distribution of data and the DVB-C standard for television signals.
Equipped with OLC technology.
Ideal for RF overlay, FTTB and FTTH applications.

Highlights
– Using OLC (Optical Level Control) technology, parameters are automatically adjusted to achieve a constant output level regardless of channel load.
– Equipped with attenuation control. Equipped with attenuation controls
– High output voltage (RF gain) and improved C/N
– Very low power consumption

Features
– DOCSIS compatible
– Two operating modes:
1. CW (Continuous Wave), in this mode the laser transmits continuously; useful in applications where the return channel
is attenuated (FTTB).

2. RFoG (RF over Glass); in this operating mode, the laser only transmits when packets to be transmitted are present; it is therefore only recommended for systems with minimal attenuation of the return channel (FTTH).

– Optical SC/APC ports and F ports for HF
– Either local power supply or remote power supply via the output F port
