The Televes 237603 Overlight converts satellite TV signals from a WideBand LNB and terrestrial FM/DAB/UHF signals into an optical signal. It is a professional solution for distributing terrestrial and satellite television over a single fibre optic strand, simplifying cabling and deployment in communal distribution networks.
Its 10 dBm optical output at 1310 nm enables passive signal distribution to up to 64 users. Thanks to CWDM technology, it can be multiplexed with other compatible transmitters in the range to carry up to 4 complete satellites plus DTT over the same fibre, making it particularly suitable for residential buildings and high-capacity communal installations.
The transmitter features 18 dB gain and adjustable WideBand equalisation from 0 to 12 dB on each satellite input, helping compensate for coaxial cable losses when the antenna is located far from the transmitter. These features make it particularly suitable for installers looking for an efficient optical headend with less intermediate electronics. Its integrated Bluetooth® connectivity also allows easy configuration and monitoring from a smartphone or tablet using ASuite.
It is designed for new installations and Overlight system expansions, rather than exclusively as a replacement part. Its combination of FM/DAB/UHF and WideBand SAT signals makes it possible to create a scalable optical infrastructure that can be completed with Overlight optical receivers at fibre-to-RF conversion points. Its high-shielding Zamak chassis and integrated power supply complete a robust solution designed for indoor installation.

Practical applications of Televes Overlight Indoor Optical Transmitter FM/DAB/UHF/SAT 1310nm/10dBm
Example 1. Terrestrial and satellite TV distribution in a residential building:
In a communal installation serving multiple dwellings, the Televes 237603 can receive terrestrial FM/DAB/UHF signals together with the V and H outputs from a WideBand LNB and convert them into a single optical signal. Its 10 dBm output makes it possible to design a passive optical distribution network for up to 64 users, reducing intermediate electronics and simplifying the building's distribution infrastructure. :contentReference[oaicite:6]{index=6}
Example 2. Multi-satellite CWDM distribution over a single fibre:
In projects where several complete satellite signals must be distributed together with terrestrial TV, the 1310 nm CWDM output can be multiplexed with other compatible Overlight transmitters operating at different wavelengths. This architecture allows the installation to carry up to four complete satellites and DTT through a single optical fibre, maximising capacity while limiting the amount of fibre required throughout the building. :contentReference[oaicite:7]{index=7}
