INTRODUCTION

The DVM-1000 9 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 69 dB. The system will support one video, up to 2 audio and up to 3 data
channels per optical wavelength.
multiple optical sources to share a single fiber, doubling the capacity of fiber optic cables.
Applications incl ude 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 i n 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.

FEATURES and OPERATION

!!!!!! DANGER !!!!!!

INVISIBLE LASER RADIATION

AVOID DIRECT EXPOSURE TO BEAM

OUTPUT POWER MAX: 2 mW. WAVELENGTH: 1300/1550 NM. CLASS III b LASER

The optical laser transmitter may harm the human eye. Proper eye

protection should be used at all times when working with laser. Please read the entire

manual before operating the Fiber Optic devices.

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 9 bit Video Analog
to digital conversi on and a 24 bit Audio A to D conversion. By using 9 bits we are able to
achieve a Signal to Noise rati on of over 69 db. The system is ultra linear and distortion free
giving differenti al gain and phase of less than 0.3 % and 0.3 degrees, respectively. The video
input and output signals are back-porch cl amped.

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.
