The SVA 1 Single-mode Variable Attenuator advances fibre optic field testing by offering superior performance in a low cost hand-held package. Utilizing a simplified, industry accepted attenuation technique, the innovative design of the SVA 1 offers superior resolution across the entire 60 dB dynamic range.
Intended for field testing during installation, new equipment turn-ups, or routine maintenance, the SVA 1 is a complete, easy to use attenuator. Its unique features allow
bidirectional signal transmission with no loss penalty.
The SVA 1 is available with a variety of connectors and reflectance options to better than 60 dB. With only two adjustments, COARSE and FINE, the SVA 1 is simple to understand and operate. The SVA 1 is suited for all single-mode applications including Telco, LANs, WANs, Video, and CATV. |
