Televes Overlight CWDM Optical Transmitter
Product Overview
The Televes Overlight CWDM optical transmitter is specifically designed for outdoor installation, positioned near the LNB. It is intended for transmission solutions of four satellites to up to 64 users. This device receives satellite signals from a WideBand RF LNB and terrestrial band signals, making them available through an optical fiber output at 1510nm, with an optical power of 9dBm.
Due to its efficient electronic performance and low attenuations, it allows for a reduction in the number of necessary amplifiers, simplifying implementation in large-scale projects while preserving signal quality throughout the installation. It is also recommended for use in GPON installations.
This device is part of the Overlight system, which distributes satellite and terrestrial signals to various users via a single optical fiber. Amplification is supported.

Wideband Technology
WideBand (also known as FullBand) refers to broadband transmission technology that utilizes a wide range of frequencies. In broadband TV systems, a substantial part or the entirety of the frequency spectrum is available to users. It can be used in fiber optic installations over long distances or in coaxial networks in combination with multiswitches adapted to this technology.
In WideBand technology, the LNB captures the signal from a satellite and distributes it through 2 universal outputs (vertical -V- and horizontal -H-), each with a combination of the high (H) and low (L) bands, within a frequency range of 290 to 2340 MHz.
Although Quattro technology is currently the most used in TV systems, WideBand technology offers significant advantages for installation:
- Simple, fast installation with less cabling: In WideBand technology, the number of coaxial cables connecting the LNB and multiswitches is halved compared to traditional installations with Quattro LNBs, allowing for a simpler and faster installation.
- Wider bandwidth than other technologies: WideBand technology allows for the transmission of more information due to its wide bandwidth (290-2340MHz), providing users with a greater number of services.
- Installation reuse: WideBand technology allows for signal distribution by reusing an existing Quattro installation. By utilizing the 4 cables from a single satellite, it is now possible to receive and distribute signals from up to 2 satellites, requiring only the replacement of devices (LNBs, MSWs, etc.) to be compatible with WideBand technology.
