1. OVERVIEW
The 7707DT series Fiber Data Transceivers provide an economical method of transmitting multiple bi-
directional RS-232, RS-422, RS-485 data signals as well as Linear Time Code (LTC) over a single fiber
optic link. Another 7707DT Data Transceiver facilitates conversion back to RS-232, RS-422, RS-485 data
signals and LTC at the destination. The 7707DT-GPIO version provides additional channels of RS-232,
and General Purpose Input/Outputs (GPIO). A pair of 7707DT Data Transceivers permits bi-directional
data transmission over distances up to 50 Km, with minimum possible latency.
Two optical interface configurations allow the user to choose the optimal function /price /performance ratio
to suit a particular application. The standard configuration transmits and receives over a single fiber. The
dual fiber configuration is compatible with CWDM systems and is designed to transmit and receive over
separate fibers. The optical output of the 7707DT is available in 1310nm, 1550nm, or any one of up to
sixteen CWDM wavelengths.

•
7707DT version transports four RS-422 or RS-485, three RS-232, and one LTC.
•
7707DT-GPIO version transports four RS-422 or RS-485, eight RS-232, eight GPIO, one LTC.
