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|
