Mandrels for Multimode Transmit Reference Cables

When testing multimode links using an overfilled LED source, always wrap the transmit reference cable five (5) times around the proper diameter mandrel. This is specified by TIA/EIA-568-B and improves insertion loss measurement repeatability and accuracy. Do NOT use mandrels on multimode receive reference cables or singlemode reference cables.
