OTS-111D MM Fiber Meter & Source
Siecor’s OTS-100 and OTS-200 series Optical Meters and Testers are powerful hand-held tools that combine an optical power meter and dual wavelength stabilized light source (multimode or single-mode, testers only) into a single unit. The testers’ single source outputs allow dual wavelength testing with a single connection; the wavelengths of both the source and meter are automatically switched with the single press of a key. Their combination of practical features, simple operation, field performance, and rugged design make them perfect for virtually all fiber optic environments including LAN, Telco, and CATV.
