The Exfo FLS-2100 Optical Light Source is a variable-output light source for optical testing applications including insertion loss, continuity, and fiber identification. It supports standard telecom wavelengths across LED and laser emitter types, with output power adjustable in 0.1 dB increments. The unit delivers stable, singlemode-compatible output through precision optical components and steady drive circuitry. Operation spans 0°C to 40°C with a 1-hour warm-up period for optimal stability. The FLS-2100 functions as a standalone instrument or integrates into 19-inch rack configurations, offering remote control via GPIB, Ethernet, and RS-232 interfaces when paired with compatible platforms such as the IQS-500 or IQS-600 Intelligent Test Systems.
