Laser Safety

WARNING

Some modules in this series may use a Laser Diode transmitter. This paragraph applies only

to them.

Class 1 Laser. Do not stare into a connector port or fiber.

Laser Radiation

The unit is a CDRH Class 1 laser device. Although this means it is eye safe,

you must avoid

looking directly at, or staring into, the laser beam located on an ST connector or on the end of a

fiber.

Infrared radiation is produced at the fiber connection port on the rear of the unit and at the end of

unterminated optical fibers that are attached to this port. Avoid long, direct exposure to the light

that comes from these sources.

Do not enable the laser when there is no fiber attached to the fiber connection port.

Do not attempt any type of service to this instrument other than so instructed in this manual. Refer

servicing to Telecast Fiber Systems, Inc.

FCC Part A Notice

This equipment has been tested and found to comply with the limits for a Class A digital device,

pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection

against harmful interference when the equipment is operated in a commercial environment. This

equipment generates, uses and can radiate radio frequency energy and, if not installed and used in

accordance with the instruction manual, may cause harmful interference to radio

communications. Operation of this equipment in a residential area is likely to cause harmful

interference in which case the user will be required to correct the interference at his own expense.

CEWarning

This is a Class A product. In a domestic environment this product may cause radio interference, in

which case the user may be required to take adequate measures.

Introduction

The Telecast Viper is a modular, user-reconfigurable fiber optic communication system for the

field acquisition of video and audio signals. Plug-in I/O modules inside the Viper chassis transmit

electrical signals from a remote location by converting them to optical signals and transmitting

them over fiber at distances of 20 km or more. The signals are then reconverted back to standard

electrical signals at a base location, such as a production vehicle or transmitter. Return signals can

also be transmitted from the base site back to the remote location.

Fibers connect the transmitter (TX) module with its corresponding receiver (RX) module. A

Wavelength Division Multiplexer (WDM) option, available from Telecast, combines two modules

onto a single fiber, thus reducing by one-half the number of fibers needed.

Modules are housed in two factory configured modular chassis units which contain the electronics

and electro-optics modules. Viper models are housed in TelecastÕs portable

Mussel shell

chassis or

mounted in a standard 19 inch rack.

Portable and rack mount units are electrically compatible and can operate together as transmitter

and receiver. Each chassis is equipped with an alarmed internal battery backup. Standard chassis

configurations are listed in Table 1, and are discussed in detail beginning on page 11.

This manual describes the systemÕs five standard chassis configurations and the internal plug-in

function modules necessary for system operation.

Applications

The Viper is suitable for use in both portable and fixed applications such as those listed in

Table 2.

The Viper can be used in conjunction with other Telecast products. Figure 1 illustrates a typical

portable application. In the figure, the Viper is combined with the Telecast Adder for a high

capacity, single cable announce booth connected to an outdoor broadcasting (OB) van at the base

location. This configuration supplies 4 video connections and 72 audio connections.

Figure 1. Portable Application

Unpacking

Inspect the units for mechanical damage, and the electrical connectors for bent or damaged pins

and latches. Report any damage to the carrier and to Telecast Fiber Systems, Inc.

Note:

Leave the protective caps on the optical connectors whenever the fiber is disconnected.
