Mandrels for use with 50 and 62.5 µm multimode test jumpers with 3 mm jackets

TIA/EIA-568-B specifies that attenuation (insertion loss) measurements of multimode fiber links for all applications must be made using an overfilled light source, such as an LED, with a mandrel-wrap mode filter on the transmit jumper. A key advantage of this specification is that it allows the use of existing overfilled LED light sources to certify both 50 and 62.5 µm fiber links for current and planned high bit rate applications including Gigabit Ethernet and 10 Gigabit Ethernet.

To meet the new multimode light source requirements in TIA/EIA-568-B, we offer mandrels for 50 and 62.5 µm test jumpers with 3 mm jackets. Both mandrels have grooves to ensure that jumpers are wrapped exactly five times (as specified by TIA/EIA-568-B) and can be easily attached to test jumpers in seconds without tools or tape.

Features

• Required by TIA/EIA-568-B to measure attenuation on multimode fiber links
• Enables certification of multimode links for Gigabit and 10 Gigabit Ethernet
• Allows existing 850/1300nm LED light sources to test 50 and 62.5µm links
• Attaches to 3mm jumpers in seconds, without tools or tape
