Bi-directional, ORL & Optical Loss Test Sets

Our range of high performance Optical Loss Test Sets (OLTS) and Bi-directional Testers are ideally suited to demanding customers. Featuring versatile multimeter-type performance in a single unit, they cover the range from a basic source / meter unit, through to some of the most advanced and integrated handhelds available. Some models have very high-end accuracy specifications too.

What is a Loss Test Set?

These instruments combine up to 6 sources, a power meter & optional VFL in one unit. Two OLTS are usually used to measure losses on installed systems. Alternatively, some users may prefer either a higher performance two-way LTS, or a separate source and meter test kit. All Kingfisher OLTS are colored red for easy work site identification, and they are inter-operable with any other Kingfisher Autotest sources, meters or two-way testers with matching wavelengths.

For larger organizations, loss test sets can provide benefits in terms of simplified asset management, deployment and training, compared to sources & meters.

For laboratory, QA and bench users, a loss test set provides maximum functionality from a single instrument. It may be an easy and more compact solution with only one battery or power pack to manage.

All Kingfisher less test sets offer superior measurement stability in practical link testing. When a test lead is repeatedly re-connected to the light source, the coupled power varies by < 0.1 dB. A Kingfisher OLTS can also be used as a tone generator for use with a clip-on identifier.

Note: Optical Loss Test Sets can alternatively be called: optical multimeters, fiber cable analyzers, or fiber cable certifiers. 

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

Kingfisher Two-Way & ORL Loss Test Sets perform Loss & Optical Return Loss (ORL) testing, i.e. they simultaneously test loss & ORL in two directions, at multiple wavelengths, 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.
