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.

FIBER OPTIC CONNECTION

Select a quality fiber optic cable containing either 62.5/125 multimode fiber or 9/125 single mode µ fiber.
Attach ST style fiber optic connectors using the connector manufacturer's recommended procedures. Attach
one end of the fiber optic cable to the ST connector on the VT4000M Series module. Attach the opposite end of
that fiber to the ST connector of a compatible IFS video receiver.

MOUNTING STAND-ALONE UNITS

Hold the VT4000M Series module against the mounting surface and mark the locations of the keyhole
slots on the rear mounting brackets. Install mounting screws into keyhole marks, allowing leeway under the
screw heads for the box to be mounted. Mount the brackets over the screws, slide, and tighten.

VIDEO LINK OPERATION

Make sure that power is applied to the VT4000M Series module, camera, and video monitor. Ensure that
the camera and monitor are turned on, and that any lens cover on the camera has been removed. Verify that
coaxial cables and fiber optic cable are properly connected (i.e., the same fiber connects to the video input and
output on transmitter and receiver). Successful link operation should be visible at this point as witnessed by a
good quality video picture on the monitor.
