12F OM3 Armored MPO-MPO Trunk Cable -3.0mm
The 12-fiber OM3 armored MPO-MPO patch cord is a ruggedized, high-performance multimode fiber optic interconnect designed for short-reach, high-bandwidth applications in data center and enterprise environments. Terminated with 12-fiber MPO connectors on both ends, this patch cord delivers reliable multi-fiber connectivity with enhanced mechanical protection through its armored cable construction, making it ideal for parallel optics transceiver-to-transceiver links.
Description
Design Principles
Armored Cable Construction. The cable integrates a helically wound stainless steel interlock armor layer surrounding the 12-fiber bundle, providing crush resistance ≥440 N/10 cm, full rodent protection, and superior impact and abrasion resistance. The armored design eliminates external conduit requirements in exposed cable runs—such as under raised floors, overhead cable trays, and between adjacent racks—reducing both material and installation costs in demanding environments.
OM3 Multimode Fiber Core. The patch cord houses twelve 50/125 μm laser-optimized multimode fibers (OM3, IEC 60793-2-10 Type A1a.2), supporting 850 nm VCSEL-based transmission with effective modal bandwidth (EMB) ≥ 2000 MHz·km. OM3 fiber enables 10GBASE-SR up to 300 m and 40G/100GBASE-SR4 up to 100 m, providing a cost-effective solution for intra-rack and inter-rack connectivity.
MPO Connector Technology. Both ends feature MPO connectors with precision-molded single-row MT ferrules housing twelve fibers. High-accuracy stainless steel guide pins ensure sub-micron alignment for repeatable, low-loss mating. Available in Type A and Type B (key-up/key-down) polarity configurations per TIA-568.2, supporting Method A and Method B polarity schemes for parallel optical links.
Optical Performance. MPO connectors achieve insertion loss ≤ 0.35 dB per mated pair and return loss ≥ 20 dB. Every assembly undergoes 100% end-face inspection per IEC 61300-3-35 and IL/RL verification per IEC 61300-3-4.
Environmental Compliance. Available in LSZH or OFNP jacket options, compliant with IEC 60754-2, IEC 61034-2, and NFPA 262. Operating temperature: -20°C to +70°C.

Benefits of Armored Fiber Patch Cable
Common fiber optic cable is fragile, which needs to be protected, especially when in harsh applications where cables could be compromised by rodents, constant wear and tear or weather damage. Armored fiber patch cable retains all the features of standard fiber cable but is much stronger due to its extra layers of armor. With the protection of flexible and durable steel tube, armored fiber patch cable will ensure the excellent operation of your network.
