Televes Overlight CWDM Optical Transmitter (237509)
Product Overview and Technical Specifications
Product Description
Model: Overlight optical transmitter CWDM
Type: Indoor use, 2SAT+DTT, 1310nm, Po 10dBm
Reference: 237509
Enhanced electronics and optical engineering to light up your TV.
The CWDM optical transmitter is specifically designed for 2-satellite and DTT installations. It receives one polarity and one band from each of the two satellites, as well as the terrestrial signal. These signals are multiplexed and distributed to up to 64 users via a fiber output in the 1310nm window with 10dBm optical power.
Its optimized electronics and low losses enable a reduction in the number of required amplifiers and simplify deployment in collective installations, preserving signal quality throughout the process.
This device is part of the Overlight system, which distributes satellite and terrestrial signals to multiple users through a single optical fiber. It supports amplification.
This product is certified with the European IRS Certification Scheme mark, indicating it has passed relevant tests according to the latest EICS test specification, available from the DTG or CAI.

Application Examples
DTT + 2 SAT up to 128 users
This diagram illustrates a system setup for distributing Digital Terrestrial Television (DTT) and two satellite signals (SAT1, SAT2) to up to 128 users. The input signals (UHF, DAB, FM, SAT1, SAT2) are fed into an Avant splitter. From the splitter, signals go to two OVERLIGHT TX (transmitter) units, each powered by a PSU. The TX units output signals via optical fiber through a PON (Passive Optical Network) system, which includes optical splitting. PAUs (Passive Optical Network Units) receive the optical signals and distribute them to multiple OVERLIGHT RX (receiver) units. Each RX unit then splits the signals to individual users via coaxial cable and data cable connections. The diagram shows separate paths for terrestrial and satellite signals, with specific connections like Terr. + FI, Terr. + FI1, Terr. + FI2.
DTT + 2 SAT up to 64 users
This diagram shows a similar system configuration for distributing DTT and two satellite signals (SAT1, SAT2) to up to 64 users. The setup involves input signals (UHF, DAB, FM, SAT1, SAT2), splitters, OVERLIGHT TX units with PSUs, optical fiber distribution via PON and optical splitting, PAUs, and OVERLIGHT RX units. The RX units then distribute signals to users via coaxial cable and data cable. The diagram highlights the connections for terrestrial and satellite inputs, including Terr. + FI, Terr. + FI1, Terr. + FI2.
