Optical receiver that converts input optical signals into RF DVB-T signals to transmit them over a distribution network.
Produktnummer: DT-620

The DT-620 is an optical receiver that converts optical input signals into RF for their transmission over a distribution network.

In order to travel for long distances the RF signal was previously converted into optical by the DT-610. Once at the other end of the link the DT-620 converts it again to RF thus recovering the original signal. The system is optimised to work with DVB-T and DVB-C channels.

This module is suitable for optical links of up to 40 km (depending on the number of channels). The optical input supports wavelengths from 1100 to 1600 nm.

OPTICAL INPUT From 1100 to 1600 nm (input power from 1100 to 1600 nm)
RF OUTPUT From 470 MHz to 862 MHz
LINK (WITH TRANSMITTER DT-610) Gain 0 dB ± 3 dB (at 0 dB of optical loss)
Flatness 2 dB
