Encircled Flux Meter

Encircled Flux is now widely accepted as the preferred way to specify modal filling by IEEE, TIA and IEC. Measurement of Encircled Flux is defined in FOTP-203 – the “Modal Explorer” is the most standards-compliant measurement system available today and has been chosen by major standards labs in the USA and Europe as the basis for their critical measurements

Its compact size and solid design make it the tool of choice in cable makers, fiber optic instrument companies and VCSEL, laser and LED source makers. In use in factories every day, major players in the industry rely on the Modal Explorer.The Modal Explorer is available for measurements at 850 and 1300nm as well as other custom wavelengths. Modal Explorer makes measurement of Encircled Flux easy and accurate, and it complies with international standards.

But if you are measuring laser-based transmission light sources for multi-mode systems you may need to use a test jumper assembly and fiber shaker in order to avoid “speckle”. Industry standards, for example IEEE 802.3aq and FOTP–203, call for the use of a mechanical fiber shaker. The Fiber Shaker (MPX-SR3 option) reduces speckle by changing the differential path length of the modes in the fiber. The fiber is shaken continuously to allow the speckle to be averaged out. This will ensure sufficient repeatability for the measurement of the Encircled Flux

Features & Benefits

• End face inspection mode with focus indicator to give better repeatability from operator to operator

• Power monitor - optimize light throughput and modal conditions simultaneously

• Real-time measurement - adjust modal conditions easily as well as increase productivity

• Internal LED with fully filled launch condition

• USB2.0 connection gives portability - with the optional carrying case plus a laptop computer

• Optional geometrical calibration artefact to enable user calibration of MPX

• API software control feature designed for use in the production environment

Applications

• Source and patchcord characterization for IEC11801 and TIA/EIA568 LAN testing

• VCSEL characterization for Gigabit Ethernet IEEE 802.3

• Mode-scrambler and mode-filter characterization

• Connector inspection n Measure sources to IEC 61280-4-1

• Alignment of pig-tailed light sources

ODTR Launch Boxes

When measuring fiber optic cables using an OTDR, a launch box (also known as a Dead Zone Eliminator) helps to minimize the effects of the OTDR’s launch pulse thus improving the accuracy of the measurement. Our high quality launch boxes come in three different housing formats:

1. Rugged “PELI” boxes versions are airtight, watertight and incredibly tough. These military approved cases are IP65 rated and are used in the harshest environments. Select this version if you want the best protection for your lead-in fiber.

2. Aluminium “EuroCard” enclosure is smaller, lighter than the PELI case offering an ideal solution for factory or lab environments where space is at a premium.

3. ABS “Midi”style enclosure is slightly larger than the “Euro” for longer fiber lengths.

We can supply a range of products in different fiber types including versions with “ModCon” mode control to enable your OTDR to meet the Encircled Flux launch condition requirement in IEC 61280-4-1.

All our boxes come with a full test certificate and 1 year warranty (except damaged connectors)

We offer a standard range of products but we also have the capability to make custom solutions to your precise requirements.

Features & Benefits

• Improve OTDR measurement accuracy

• Available with “ModCon” Launch conditioning to allow compliance with EF requirements of IEC 61280-4-1

• Rugged carrying case for long lifetime in field or factory

• Available in 09/125SM, 50/125MM, 62.5/125MM

• Custom configurations available

• User replaceable input and output leads (fusion splicer required) for long life time

• High quality components e.g. Draka PCVD GIMM fiber

Applications

• OTDR testing in field or factory

• Remove the “dead zone” from OTDR measurements

• Calibration comparison for OTDR measurements

• Long haul system loop back for field testing transmissions
