Fiber Optic LED Test Source KI9812A
The shirt-pocket size KI 9812A Pocket Fiber Source is ideal for general testing of multimode, PCS or POF systems at 850 and 1300 nm. It provides, high accuracy and simplicity of use.
It can also achieve useful short-range testing on singlemode systems at 1300 nm, since it has a specified output level into SMF.
- Encircled Flux compliant modal distribution
- Rugged, drop-resistant construction
- User defeatable auto turn-off
- Excellent stability
- Lanyard, shirt pocket clip & padded pouch
- Tone generator & Multi-Fiber ID function
- Easy use TamperLock mode
- Compatible with Autotest power meters
- Interchangeable connectors
- Full QA reports with ISO9001 compliant calibration

Interchangeable connectors
