The FVT/FVR8018SHR are part of ComNet's SHR product family. The FVT8018SHR
transmits eight channels of video and eight channels of bi-directional data over its
two fiber optic interfaces. The FVR8018SHR receives eight channels of video and
eight channels of bi-directional data over its two fiber optic interfaces. The
FVT/FVR8018SHR are fully compatible with the other products in ComNet's SHR product
family (e.g. FVT/FVR1010SHR and FVT/FVR4014SHR).
The NTSC or PAl video signals are digitized with 10-bits of resolution providing
superior image quality. The link also transmits bi-directional data over the same fiber.
Each data channel can be configured for an electrical interface of RS232, RS422 or
RS485 (2 Wire or 4 Wire).
Utilizing wave division multiplexing (WdM) technology, only one optical fiber is required
between units. It's possible to implement a fully self-healing ring, linear add-drop, and even
point-to-point topologies. A maximum of eight (8) video signals can be placed onto the ring
through any combination of transmitter units, and an unlimited number of receiver units
can be used to view any or all of these eight video signals.
bi-Color (Red/Green) lEd indicators are provided for rapidly ascertaining equipment
operating status including the location of fiber breaks. See Figure 10 on Page 7 for an
explanation of lEd indicators. An alarm relay output on the FVR8018SHR indicates when a
fault has occurred anywhere in the system.
These units are interchangeable between stand-alone or card-cage mount configurations.
See Figure A on Page 11 for mounting instructions.
See Figures 1 – 13 for complete installation information.

The system demonstrates a video distribution application. A single video input is transmitted by a FVT1010SHR over fiber optic cable to three daisy-chained FVR1010SHR units. The last unit in the chain is connected to an audible alarm to indicate faults.

Eight channels of video enter the system at the five transmitter units and are sent to the video receiver and are displayed on a bank of monitors.
