2.2 Equipment Description
The system is capable of transmitting and receiving 1 simplex video signal and 1
duplex audio channel over 1 optical fiber.
Depending on the distance requirements between sites, the VAB700XD Series may
be equipped to operate over multi-mode fiber or over single mode fiber. Distances
between the transmitter and receiver can be up to 10 Km for multi-mode operation
and up to 110 Km for singlemode operation.
The VAB700XD system employs uncompressed analog to digital modulation
techniques, which provides for superior receiver output stability and is unaffected by
changes in the fiber path attenuation caused by environmental factors, splicing or
aging.
The VAB700XDT accepts the baseband video signal for transmission via an optical
digital carrier over a single optical fiber. At the distant end, the VAB700XDR receiver
accepts the optical carrier and converts it to the output video channels.
