INTRODUCTION
The DVM-2000 12 Bit Video and 24 Bit Audio Fiber Optic Transport offers state-of-the-art
performance exceeding RS250C Short-haul and Broadcast Specifications with a Signal to Noise
ration exceeding 75 dBs. The system will support one video, up to 6 audio and up to 3 data
channels per optical wavelength.
The user can (WDM) Wave Division Multiplex, permitting
multiple optical sources to share a single fiber, doubling the capacity of fiber optic cables.
Applications include links from studio to transmitter, studio to studio, studio to CATV head-end,
distance learning and backhaul feeds from special events. The transmit and receive units are
available in portable and rack-mount packages making the system ideal for both field and studio
applications. The transmit unit includes a 1000 feet post-equalizer for 8281 type cable.

WARNING
HIGH VOLTAGES INSIDE
The unit should be only serviced or opened by qualified personnel.
There are no user serviceable parts or adjustments inside.
VIDEO CHANNEL
The video performance of the fiber optic system exceeds RS-250C Short-haul
specifications. The system uses state-of-the-art technology to offer a true 12 bit Video Analog
to digital conversion and a 24 bit Audio A to D conversion. By using 12 bits we are able to
achieve a Signal to Noise ration of over 75 dBs. The system is ultra linear and distortion free
giving differential gain and phase of less than 0.3 % and 0.3 degrees, respectively. The video
input and output signals are back-porch clamped.
The system has a video bandwidth of 8 MHz. The transmission of NTSC, PAL, SECAM
and video with diplexed audio carriers at 4.5 MHz, 5.8 MHz and 6.4 MHz are fully compatible
with the fiber optic system.
