The VCS-20A Multifunction Fiber-Optic Talk Set brings together four convenient tools in a single test set, combining a full-duplex digital talk set, a stable light source, a 2 kHz tone generator and a 2 kHz tone detector. The VCS-20A can be configured for singlemode and multimode applications with LED or laser sources. Multiple Applications The VCS-20A fulfills more than simple communication needs. In fact, the light source is calibrated and is stable in time and temperature. Use continuous wave selection to perform attenuation and insertion loss tests. Why carry an extra source when one VCS-20A does it all?
Extended Dynamic Range Two new configurations have extended the VCS-20A’s dynamic range to 50 dB. This wide range makes it possible to use new applications requiring clip-on devices. Easy-to-Use Talk Set This unit is rugged and provides high-quality voice communication over a single fiber. The unit’s hands-free operation is convenient and simple: press the Talk button to send or receive a call. As usual, conversations are as clear as if both operators were in the same room. Powerful and Durable For hours of flawless operation, the three-way powering function automatically selects the best alternative among the choices of rechargeable NiMH battery, 9 V alkaline backup and AC adapter/charger input. Its rugged waterproof casing and protective holster make the VCS-20A the preferred field-testing instrument in the outside plant industry.
