Encircled Flux Multimode Adapter

New generation of Multimode Fiber Adapters adds full standards compliant fiber certification capability

A light source and power meter are used to measure the power loss and length of optical cables at 850 and 1300 nm. Certification of Multimode fibers has often been a contentious issue due to the inherent uncertainties in the measurement process. ISO/IEC and TIA have recently adopted a Encircled Flux (EF) standard that standardizes the launch condition for the light sources used in Multimode test equipment. The WireXpert’s new EF compliant adapters give you guaranteed compliance to the EF standard IEC 61280-4-1.

  • Compliant to IEC- 61280-4-1 EF standards and IEC-14763-3
  • Provides validation to different modal behaviors of various fiber optic manufacturers
  • Interchangeable robust SC, LC and ST adapter for EF kit
  • Provides troubleshooting with built-in Visual Fault Locator (VFL)
  • Improves repeatability of measurements
  • Reduces insertion loss variation between laboratory and field instruments

Highlights

  • One cable certifier to test copper- as well as multimode-, singlemode and MPO/MTP-fiber installations.
  • Improve productivity of technicians with easy setting and fast testing
  • Test single fiber links, trouble-shoot links with light source and power meter tools
  • Easy pictorial work-flow makes it easy to avoid human errors in testing

FAQ

With the WireXpert and fiber adapters you can perform a fully standards-compliant certification measurement Tier 1 (e.g. according to ISO / IEC 14763-3). Additionally, an automated evaluation of the attenuation of the fiber link is performed in terms of the number of the connectors, splices, and the length of the link.
(Automated evaluation of the link attenuation budget)

Yes, for standard-compliant measurements on fiber optic cabling (e.g. according to ISO / IEC 14763-3) you must be equipped with a fiber microscope and cleaning tools, as it is normative required to review the connector end faces for dirtiness. You would also know nothing about the dirtiness of the connectors and could unintentionally cause pollution to the fiber cabling.
