KF7XMS Fiber OWL 7X Singlemode/Multimode Auto-Testing Fiber Optic Certification Test Kit (w/ Length Testing Feature)

Reference#: 76933
Item#: KF7XMS


Fiber OWL 7X KF7XMS certification test kits are ideal for the fiber optic professional who requires standards-based certification of fiber links, including TIA-568, ISO 11801, various Ethernet standards, among others. The Fiber OWL 7 KF7XMS can also be configured with custom standards to meet the needs of various fiber optic applications.

This KF7XMS certification test kit comes with a N.I.S.T. Traceable Fiber OWL 7X optical power meter and a WaveSource Pro fiber optic light source [multimode (850/1300nm) and singlemode (1310/1550nm)].

Included with each test kit are a hard-shell carrying case, protective rubber boots, certificate of NIST-traceability, USB battery chargers and cables, and a USB flash drive with free OWLView software and operation manual. Fiber OWL 7X optical power meters come standard with a state-of-the-art UNIVERSAL adapter port system. The flexibility of universal ports saves money on consumables (since test cables wear out over time).

Encircled Flux compliant
Encircled Flux (EF) compliance is the latest requirement for testing multimode networks designed for transmission of 10 Gigabits and beyond. When used with EF mode controller cables, Fiber OWL 7 certifiers ensure high-speed multimode networks are compliant to standards-based EF requirements.

User-friendly setup and test procedures
Helpful diagrams on the screen prompt the user to connect the tester to the link as shown, and text-based help screens are available in case users have questions in the field.

Fiber OWL 7X certifiers are a fraction of the cost of bulky over-priced certifiers, saving cost conscious technicians and installers thousands of dollars that could be better used elsewhere.

Small, compact size
At nearly a third of the size and weight as compared to much bulkier ultra-expensive certifiers on the market, Fiber OWL 7X certifiers are truly hand-held pocket-sized devices that can be operated in one hand!
