Ultra-compact and additionally protected by the use of 12 fibers in a 6.5 mm thick cable and an MTP connector at each end, making it very suitable for data centers. ACT MTP/MPO cables use MTP US Conec connectors, which offer very low losses and better mechanical properties, among other advantages. Designed for use with QSFP transceivers or as backbone cabling. The OM4 fibers in these cables are backward compatible with OM3 fibers.
