The KI2800 Series Handheld Fiber Sources are used with optical power meters for testing optical loss on single mode and multimode fibers. A Multi-Fiber tone feature makes for handy continuity/polarity testing and fault finding, also for use with clip-on traffic identifiers.

The KI2800 series source provides excellent general test capability.

All emitters feature excellent repeatability and stability. Re-connection repeatability is < 0.1 dB, resulting in exceptional test accuracy.

This instrument meets the general requirements of MIL PRF 28800F class 2. The large display provides the user with an easy view of instrument status and test results.

Practical interchangeable optical connectors are easily changed, and are protected with a captive dust cover/tilt bail. Metal free adaptors help avoid contamination of connectors in high power systems.

AA alkaline batteries have long life, and the micro USB power input ensures high availability. Or use rechargeable batteries with built-in charging.

When used with a Kingfisher Autotest compatible power meter or loss test set, automatic λ identification is achieved, and the nominal source power is displayed on the power meter.

Up to 6 LED/laser sources can be specified, making this a versatile test source for mixed multimode/singlemode fiber testing.

LED sources are Encircled Flux (EF) standards compliant, to provide most consistent and reliable testing results.
