SERIES DESCRIPTION
This operating guide describes a family of International Fiber Systems, Inc. (IFS) fiber optic modems.
Not all modems have all of the features in this guide.
The VT4000M Series is designed to transmit video from a fixed Closed Circuit Television (CCTV)
camera over one single mode fiber to an IFS compatible receiver. The VT4000M Series may be mounted
directly on a fixed camera (within the housing) without the need for a coaxial cable. This transmitter utilizes
FM (frequency modulation) techniques to produce “near-broadcast quality” video images.
