The VCL-V.35 Fiber Optic Modem provides the user the
capability to establish communication between two V.35 interfaces or between
an E1/FE1 interface and a "n"x64 V.35 interface over an optical fiber link.
It establishes a secure, long range data fiber link between
computers, routers, multiplexers and other V.35 or E1 data communication devices.
The primary application for the VCL-V.35 Fiber Optic Modem
is to establish point-to-point fiber link at ranges longer than any copper modem can
