Viper I
Portable Fiber Optic Broadcast Production Systems

The Viper I family, including our reel mounted Sidewinder system, handles all your signals on one lightweight fiber cable. Both systems are modular and provide two-way video (NTSC/PAL or HD-SDI), audio, intercom and data transport. These flexible, interoperable systems let you create your own configuration of Mussel Shell, rack mounted "442" or reel mounted modular units. Use with our TAC Cable battlefield proven cables and connectors.
