Data & Clock Transmission DX/DT/DR-7401 For Medium Speed Data & Clock Applications 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.
