Televes 237641 Overlight Quattro FM/DAB/UHF/SAT Optical Receiver
The Televes 237641 Overlight Quattro Optical Receiver converts television signals received via fibre optic cable into RF signals ready for distribution over conventional coaxial cable. It is a particularly suitable solution for communal installations that aim to benefit from the low losses of fibre while maintaining conventional terrestrial and satellite TV distribution.
It operates as part of the Televes Overlight system, receiving optical signals between 1200 and 1600 nm and recovering FM/DAB/UHF and SAT signals. It features one terrestrial output and four satellite outputs in Quattro mode — VL, HL, VH and HH — making it particularly suitable for feeding a Nevoswitch multiswitch in buildings and communal distribution networks. The unit is primarily intended for new installations or extensions of existing Overlight systems, rather than simply being a replacement part for a specific previous device.
One of its key features is OLC (Optical Level Control) technology, which keeps the RF output level stable even when the received optical level or channel load changes. Its low-loss electronics help simplify communal distribution networks and reduce amplification requirements. It is also compatible with GPON deployments, features an SC/APC optical connection and can be integrated with components used in fibre optic installations.
In summary, the Televes 237641 provides an efficient fibre optic → coaxial RF transition at the distribution point while keeping the four satellite band and polarity combinations separate. Its compact design, remote powering from the multiswitch and power consumption below 5 W help create cleaner and more efficient professional installations.

Practical applications of the Televes Overlight Quattro Optical Receiver 237641
Example 1. Fibre distribution of terrestrial and satellite TV in a communal building:
In an apartment block or residential development, terrestrial and satellite TV signals can be transported through the Overlight optical network to the point where coaxial distribution begins. The Televes 237641 converts the optical signal back into RF and provides one terrestrial output together with the four Quattro satellite combinations. These outputs can then feed a multiswitch for distribution to the different users in the building.
Example 2. Optical-to-RF conversion in an installation with GPON infrastructure:
In projects where fibre-optic television distribution is deployed alongside GPON infrastructure, the Overlight Quattro receiver can recover the TV signals at the required point in the network. Its OLC technology helps maintain a stable RF output level when the optical input level varies, while its compact dimensions and low power consumption simplify installation in technical rooms, cabinets or communal distribution areas. :contentReference[oaicite:3]{index=3}
