OVERVIEW
The 7707IT series Intercom Fiber Transceivers extend multiple channels of intercom communication over
a single fiber optic link. The 7707IT-8 version accommodates eight channels of intercom, while the
7707IT-3 version accommodates three channels. Each channel is configurable as a matrix or party-line
and will interface with industry-standard intercom systems. Bi-directional analog audio, serial data, and
GPIO’s are conveniently presented in a single product. A pair of 7707IT Intercom Transceivers permits
communication over distances up to 50Km, 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 & DWDM systems and is designed to transmit and
receive over separate fibers. The optical output of the 7707IT is available in 1310nm, 1550nm, CWDM &
DWDM wavelengths.
