Optical LNBs

Triax Optical LNBs

The Triax Optical LNBs are high quality, high performance universal LNBs, that, in addition to excellent LNB performance, provides a 1310 nm wideband optical output where all four satellite polarities are stacked into one frequency range (950-5450 MHz), in addition to 155 nm optical DTT/DAB signal (TOU 232 only).

Using modern laser technology this frequency range can be transmitted via a single laser over a very large distance, at a link budget that can sustain splitting into 32 ways. This allows a system setup that can drive a fairly large Passive Optical Network (PON) before the signal is finally fed into a number of virtual converters for traditional coax distribution.

The stacking/de-stacking technology provides a very cost efficient solution, as a single laser carries the full four satellite polarities in one optical cable. This, in contrast to traditional fibre optical solutions that require one laser per polarity, is a substantial cost saving, without compromising satellite signals, range nor quality. This means that not only is the investment into fibre optical cables kept at an absolute minimum, the full PON benefit from the same savings too.

The Optical LNB is DC power sourced via a coax cable and an F-connector.

Power supply is included in the kit. A high-quality FC/PC type fibre optical connector is used for optimum outdoor performance.
