The Newport 1930F-SL is a single-channel fiber optic power meter designed for precise optical power measurements in telecommunications, data communications, and laboratory environments. This silicon-detector instrument delivers femto-Watt-level sensitivity with seven gain ranges for continuous monitoring across the visible and near-infrared spectrum. Its compact front-panel fiber connections, high-contrast display, and multi-interface connectivity—USB, GPIB, and RS-232—make it equally suited to benchtop characterization and field deployment where accurate power analysis is essential.

– Compatibility & Integration
The 1930F-SL accepts SC PC fiber connectors (variant SC model available) and integrates with Newport’s detector ecosystem. Integrated InGaAs detectors are available as an alternative for extended wavelength coverage to 1650 nm. USB, GPIB, and RS-232 interfaces support both manual operation and automated test systems. Rack-mountable chassis design enables integration into larger measurement setups.
