Lightwave VDE/200 Video Display and Audio Extension
Kit for Graphic Workstations
The VDE/200 Video Display Extension Kit allows you to
remote a keyboard, monitor, mouse, and peripherals from
a workstation long distances (up to 10,000 feet), without
loss of resolution. Using multi-mode fiber optic technology,
the VDE is commonly used in areas where space is at
a premium or where data security or environmental issues
dictate that a CPU be located remotely from the graphics
console or projector. The VDE is the only Gold Seal
Approved solution for Silicon Graphics. The VDE is also
SPARC Verified.

Lightwave VDE/200 Convenience - Access your SGI
or other graphics workstation from a remote location
(creative or production department, etc.) with just
as crisp and clear graphics as if you where still sitting
next to it.
Lightwave VDE/200 Improve your workstation environment
- Keep fan noise and CPU maintenance interruptions restricted
to the cold computer room.
Lightwave VDE/200 Flexible solution - Use the VDE
for any desired distance, from 75 to 10,000 feet. VDE
systems are available to transport RGB, HDTV formats,
NTSC, PAL, Audio, and most serial formats.
Lightwave VDE/200 High resolution graphics - Patented
automatic gain control ensures consistent, transparent
operation with resolution to 2000 x 2000 pixels.
Lightwave VDE/200 Easy to use - Plug-and-play design
with no adjustments needed. Common copper cabling connections
and simple ST fiber hook-up.
Lightwave VDE/200 Complete system/software transparency
- The VDE/200 connects directly to the video signal
outputs from your processor - no digitizing, packetizing,
routing, or signal reformatting is performed.
Lightwave VDE/200 Platform Flexible - Supports video
formats for Silicon Graphics, Sun, HP, IBM, DEC, Apple,
and other compatible processors.

Audio Extension Kit
The Audio Extension Kit allows users
to send and receive analog stereo audio, MIDI, and serial
lines without increasing the fiber count. The AES delivers
CD quality sound, fiber-optically, at 42,000 samples
per second and 18 bit digital conversion
Audio - Stereo connections to microphone
or line level sound is digitized and reproduced with
CD precision to headphones or speakers.
Additional Ports - Remote even more peripherals
(tablets, stereo view goggles, gloves, etc.) with AES's
additional serial ports.
MIDI - Additional capabilities include a
Musical Instrument Digital Interface.

VDE/200 Video Display Extension Kit
Lightwave VDE/200 Model 160 High
Performance System:
A full RGB (and sync) system, designed to handle workstation-level
video signals up to 160 MHz, as found on displays with
up to 1600 x 1200 pixel resolution.
Lightwave VDE/200 Model 350 Ultra-High
Resolution System:
The Model 350 utilizes a patented AGC scheme and proprietary
video processor ASICs and pre-amps to achieve analog
bandwidth sufficient to support 2048 x 2048 pixel displays.
When packaged with high performance LEDs and detectors,
the Model 350 has no peer for entertainment post-production,
air traffic control, medical and visual simulation applications.
The system has all the functional features and benefits
of the Model 160.

VDE/200
Q: What is the optical loss budget for the VDE/200?
A: Model 160: 7 db. Model 350: 5 db.
Q: At what distance do you recommend we consider
the VDE/200?
A: Depending upon resolution and the importance
of video integrity, generally 50 feet and longer. In
secure computing environments fiber is selected regardless
of length.
Q: How far can I extend with a single VDE/200?
A: 10,000 feet.
Q: What type of fiber should I use?
A: The VDE/200 uses FDDI grade multi-mode
62.5 micro core fiber. Fiber connections are ST. Fiber
assemblies and cables are available from Lightwave.
Q: Will the VDE/200 support my peripherals?
A: The VDE/200 supports the following user's
peripherals, Sun, Silicon Graphics, HP, Bloomberg, IBM,
DEC, RS-232, and RS-422.
Q: Can you accommodate NTSC Video?
A: Yes, there are options available to support
this video format, in addition to RGBS.
Q: How many serial devices can I attach?
A: One.
Q: How many fibers are required for one VDE/200?
A: A maximum of six depending on the configuration.
