StarTech 7m (23ft) MTP/MPO Fiber Optic Cable - 12F Type-B - OM4 Multimode MTP/PC Female Fiber Jumper - 50/125 - OFNP Plenum - OM4MTP12BOFNP7M

This OM4 MTP®/MPO multimode fiber cable supports high-density 40G and 100G connections between switches and servers, helping reduce cable bulk and simplify routing across data hall racks. The 12-fiber design supports high-speed MTP®/MPO connectivity for multi-fiber network applications, while the Erika Violet jacket follows TIA standards to clearly distinguish OM4 from Aqua OM3 cabling.
Constructed with OM4 50/125µm laser-optimized Corning glass, this cable delivers consistent high-bandwidth transmission for data center and backbone links. Type-B polarity MTP® Elite connector maintains proper transmit/receive alignment for multi-lane connections, ensuring reliable performance without additional crossover components. Each cable is individually tested for signal integrity.
