16F OM3 Double sheath Armored MPO Trunk Cable -3.5mm
The 16-fiber OM3 dual-jacket armored MPO-MPO patch cord is a high-density multimode fiber optic interconnect engineered for next-generation parallel optics in data center and enterprise environments. Featuring a robust dual-jacket armored cable construction and terminated with 16-fiber MPO connectors on both ends, this patch cord delivers superior mechanical protection and environmental resistance for 400G/800G transceiver architectures.
Description
Design Principles
Dual-Jacket Armored Construction. The cable features a two-layer jacket system: an inner LSZH/OFNP tight jacket encapsulating the fiber bundle, and an outer ruggedized jacket enclosing a helically wound stainless steel interlock armor layer between the two jackets. This dual-jacket design provides crush resistance ≥440 N/10 cm, full rodent protection, impact resistance, and an additional moisture and chemical barrier. The redundant jacket layers ensure cable integrity even if the outer jacket is compromised, making it ideal for extreme-duty deployments.
OM3 Multimode Fiber Core. The patch cord houses sixteen 50/125 μm laser-optimized multimode fibers (OM3, IEC 60793-2-10 Type A1a.2) with effective modal bandwidth (EMB) ≥ 2000 MHz·km. OM3 fiber supports 400GBASE-SR8 up to 100 m and 100GBASE-SR4 up to 100 m at 850 nm, providing a cost-effective multimode solution for short-reach, high-bandwidth links.
16-Fiber MPO Connector Technology. Both ends feature MPO connectors with precision-molded MT ferrules housing sixteen fibers in a single row. High-accuracy stainless steel guide pins ensure sub-micron alignment. The 16-fiber MPO format supports 8-lane parallel optics with 8 spare fibers or full 16-fiber transmission for 800G SR8 architectures. Available in Type A and Type B polarity per TIA-568.2.
Optical Performance. MPO connectors achieve insertion loss ≤ 0.35 dB and return loss ≥ 20 dB. 100% end-face inspection per IEC 61300-3-35 and IL/RL verification per IEC 61300-3-4.
Environmental Compliance. Dual LSZH/OFNP jackets compliant with IEC 60754-2, IEC 61034-2, and NFPA 262. Operating temperature: -40°C to +75°C, extended range enabled by dual-jacket thermal insulation.

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.
