Ultra-Stable Triple Optical Laser Source KI24010-APC
The KI 24010-APC Zero Warm-Up Laser Source is an ultra-stable triple wavelength test source for single mode systems with APC connectors, at 1310-1550-1625 nm. Typical applications include fiber optic attenuation measurement, polarity testing and fiber identification on critical systems. The Kingfisher Zero Warm-Up Laser source optical architecture ensures exceptional source stability under all conditions, including warm up, varying temperature, and varying ORL.
- Easy to use, rugged & versatile
- Long battery life, micro USB power/charger
- Interchangeable connectors with dust cap & tilt bail
- Superior re-connection repeatability, < 0.1 dB
- Excellent stability
- Autotest & Multi-Fiber ID Tone generator
- Full QA & test reports ISO 17025 traceable

Interchangeable connectors
Use a single tester for: SC, LC, MPO, FC, HFBR, & other connectors - including universal & duplex options.

One-touch AutoTest
Smart communication makes sure you always get a full, complete, and consistent test result.

Test tone with multi-fiber ID
Send & identify one of 12 unique test tones. Great for quickly verifying continuity, polarity and rack labelling.

VisiTest option
Integrates a VFL into AutoTest, so the fiber end you need to test flashes red. Confidence with a quick & easy visual cue.

Zero warm-up laser (KI2300, KI2400, KI23400 only)
Instant high-accuracy testing. Unlike other sources, Zero Warm-Up sources are in-spec & stabilized in seconds.

Legendary source stability
In real-world field conditions, Kingfisher's stable and accurate sources outshine the competition.
