What is a Two-Way / Return Loss Test Set?

Kingfisher Two-Way Loss Test Sets perform Optical Return Loss (ORL) tests, i.e. they test in two directions, simultaneously, on one fiber. This is a faster, easier and more accurate process than the "two step on two fiber" process used on many other instruments. These are today's easiest, fastest, most accurate, smallest and most integrated field instruments. 

The real-time loss display enables the user to instantly identify and correct a poor connection prior to recording the result. Associated KITS reporting software is standards compliant and data can be clicked into the acceptance report in real time.

These LTS also measure absolute power level, or generate and find tones. Two instruments are usually used to check cabling losses. Single operator pass / fail operation in a PON type environment is easily achieved. All Kingfisher LTS are colored red for easy identification. These AutoTest instruments are interoperable with any other Kingfisher AutoTest instruments with matching wavelengths.

All Kingfisher Loss Test Sets offer superior measurement stability in practical use. When a test lead is repeatedly re-connected, the coupled power varies by < 0.1 dB.
