FTTB-1218-L2W-42 2 way indoor node


The FTTB-1218-L2W (Two-Way Indoor Optical Node) converts the optical signal received from the headend into a +44 dBmV RF output, while sending upstream cable modem signals over a second fiber back to the headend. Three frequency splits are available to satisfy standard 5-42 MHz, 5-85 MHz, or 5 204 MHz returns for increased bandwidths required for DOCSIS 3.1 applications.

A future proof feature of the FTTB-1218-L2W is that its RF diplexers are able to be changed in the field to accommodate increased return bandwidth requirements when demands for more data occur.

The compact housing includes an optical receiver with an LCD display, control keys, RF AGC, adjustable
attenuator, adjustable slope, RF amplifier and a return path optical transmitter.
