Optical primary-focus LNB

Optical primary-focus LNB

Optical LNB offset

One 1310 nm output: Hh/Vh/Hl/Vl

Optical LNB converter that receives a satellite signal (4 polarity/band combinations) and transmits it over a single fibre. A local oscillator transforms the satellite frequency into an intermediate frequency in the 950 MHz-5.45 GHz range.
Signal is transmitted on the1310 nm wavelength.
The LNB is powered by a coaxial input (F connector) and a 12 V power supply (provided with the product).

The LNB is supplied in grey colour and individual packing.

The Optical Fibre interface installed in the H45 or H60 field strength meters allows you to perform optical measurements directly through the optical fibre. It can be powered by connecting a coaxial cable in parallel with the FO to the RF input of the meter and applying voltage like a regular LNB.
No. LNB power supply is always provided in parallel with the fiber. The optical LNB is powered through a coaxial cable. Hence, Optical LNBs are always equipped with two connectors: one “F” for the power supply, and an FC/PC connector for the optical fiber.
It is a plug&play range. The whole range of products is currently available (pre-terminated patch cords, splitters, attenuators, terrestrial and satellite signal mixers...). A full range of products that will help the installer provide closed quotes to their clients.
