Data & Clock Transmission
DX/DT/DR-7401
The
Litelink
DX-7401/DT-7401/DR-7401 system consists of
the DX-7401 transceiver, DT-7401 dual channel transmitter and
DR-7402 dual channel receiver. All units are designed to
transmit clock and companion data signals on a single fiber (per
channel) by utilizing Manchester encoding and decoding of the
signals. Standard digital modulation is then used to transmit the
composite signal, error free, through the fiber optic cable.
The DX-7401/DT-740`/DR-7401 are all adjustment free and
integral LEDs are provided on all units to continuously indicate
the presence of operating power and transmitter/receiver
synchronization thereby making system troubleshooting simple.
