Using Mandrels for Testing Multimode
Fiber
You should use mandrels when testing multimode fiber.
Mandrels can improve measurement repeatability and
consistency. They also allow the use of LED light sources to
certify 50 µm and 62.5 µm fiber links for current and

* For Far End Source mode with OFTM-5xx1 and 5xx2 modules, values are determined by the source and should not exceed the
maximum values. See the source's documentation for the source’s values.

planned high bit-rate applications, such as Gigabit Ethernet
and 10 Gigabit Ethernet.
The gray mandrels included with some OptiFiber models
are compliant with TIA-568-C for 62.5 µm fiber with a 3 mm
jacket. Mandrels for 50 µm fiber are available from Fluke
Networks. Refer to the appropriate standard for mandrel
requirements if you follow other standards.
