Televes Overlight CWDM Optical Transmitter
Model: OLT1310KA (Art. 237513)
EAN13: 8424450271865
Product Overview
The Televes Overlight CWDM is an external optical transmitter designed for terrestrial and satellite CWDM broadband applications. It is specifically engineered for outdoor installations, requiring minimal distance from the LNB. This device receives a complete satellite signal from a WideBand RF LNB and terrestrial band signals, distributing them to up to 64 users through a single fiber output operating at 1310 nm with an optical power of 10 dBm.
Its advanced electronics and optimized optical design result in low losses, reducing the need for amplifiers and simplifying the implementation of communal installations while preserving signal quality throughout the process. This device is part of the Overlight system, which distributes satellite and terrestrial signals to multiple 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 frequency range. In WideBand TV systems, users have access to a substantial portion or the entire frequency spectrum. It is suitable for fiber optic distributions requiring long cable runs or for coaxial scenarios in conjunction with multiswitches adapted to this technology.
In WideBand technology, an LNB captures a complete satellite signal and distributes it through two universal outputs (Vertical -V- and Horizontal -H-), each carrying a combination of high (H) and low (L) bands, within a frequency range of 290 to 2340 MHz.
While Quattro technology is commonly used in TV systems today, WideBand technology offers significant installation advantages:
- Simpler, Faster, and Cleaner Installation: WideBand technology requires half the number of coaxial cables connecting the LNB to the multiswitches compared to traditional Quattro implementations, leading to quicker and easier installations. Fewer cables also result in a tidier system.
- Wider Bandwidth: WideBand channels can carry more information due to their extensive bandwidth (290-2340 MHz), enabling the delivery of more services to end-users.
- Reusable Distribution: WideBand technology allows signal distribution by reusing existing Quattro installations. It is possible to distribute signals through the existing four cables descending from the roof, capturing signals from up to two satellites, by simply changing the LNB and multiswitch to be WideBand compatible.

Diagram Description
The diagram illustrates a typical installation of the Televes Overlight system. It shows a satellite dish and a terrestrial antenna connected to a headend unit. From the headend, a signal is transmitted via optical fiber to a distribution point labeled "PON 64". This distribution point then sends the signal via optical fiber to multiple user terminals, each labeled "OVERLIGHT". The system includes the main transmitter unit, an LNB, a multiswitch (Avant X), and the optical distribution components. Power supplies are also depicted.
