The CWDM is an optical transmitter specifically designed for indoor installation. This device receives a satellite signal from an RF WideBand LNB and terrestrial band and distributes it to up to 64 users via a fiber optic output in the 1310nm window with 10dBm optical power. Thanks to the optimized technology and low losses, the number of amplifiers required can be reduced, making it easier to use in shared facilities, while maintaining signal quality throughout the process., This device is part of the Overlight system, which distributes satellite and terrestrial signals to multiple users over a single fiber optic cable.It can also be amplified.
