The DT-620 is an optical receiver that converts input optical signals into RF DVB-T signals to transmit them over a distribution network.

In order to cover a certain distance, the digital signal is converted into an optical signal through a converter (such as the DT-610) and once at the other end of the link, the DT-620 does conversion again to DVB-T, recovering the signal.

The module has an optical SC input and an RF type BNC output. Input is demodulated and optimized to broadcast on DVB-T and DVB-C digital channels.

At the BNC module output there is released an RF signal. Then it can be inserted into a distribution network with the advantages of robustness and high quality offered by the digital technology.

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

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