For UAE project teams, the key is to match this exact configuration to the port schedule, optical budget and delivery documentation. This duplex armored patch cable terminates two LC UPC connectors on an OM4 50/125µm multimode unit wrapped in a helical stainless steel tube. While the steel armor beneath it absorbs the crushing, pulling and rodent damage that interrupts unprotected patch cords, the aqua 3.0mm riser-rated (OFCR) jacket identifies the multimode grade at a glance. Bend-insensitive OM4 glass keeps the link stable where the path turns tightly through trays and rack posts.

Specifications

OM4 multimode for 10G to 100G short-reach links

OM4 is the workhorse multimode grade for 850nm VCSEL optics. It carries 10GBASE-SR to 400m, 40GBASE-SR4 and 25G-class links comfortably, and supports 100GBASE-SR4 breakout pairs and bidirectional duplex optics over the distances typical of data center rows and hardware rooms. Because the duplex LC interface matches SFP+, SFP28 and QSFP-series ports directly, one armored cord series covers most short-reach multimode links without adapters.

Aqua identification in dense patching fields

The aqua jacket follows the industry color convention for OM3/OM4 multimode, which speeds up tracing and reduces cross-interface errors in crowded frames. The steel armor sits invisibly under that jacket: the cord dresses and identifiers exactly like a standard patch cable, yet survives being stepped on, pinched by floor tiles or dragged across a tray edge during rework.

Why armor a multimode patch cord

Multimode links frequently run in the most exposed parts of a building: under raised floors, across warehouse ceilings, through retail or industrial spaces shared with power cabling and foot traffic. Conduit adds cost and locks the path in place. With the helical steel tube built into the cord itself, the pathway stays flexible, this cable count in the tray stays low, and a damaged connection normally means re-terminating nothing more than a single replaceable jumper.

Routing and installation notes

The armored cord bends and dresses like a standard 3.0mm jumper, with two differences worth respecting: keep the path inside the 20/10D bend-radius limits of the OM3/OM4 glass, and avoid crushing the coil under heavier power cables when trays are shared. In under-floor runs, lay the cord flat rather than coiled on edge, and leave the factory coil memory to relax before final dressing. The steel tube holds its shape well, which makes neat right-angle exits from managers easier than with loose-buffered patch cords.

Length options and customization

Standard length options are stocked for fast delivery: 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 10m (33ft), 15m (49ft), 20m (66ft) and 30m (98ft), covering the common rack-to-rack, access and frame connections this cord is built for. Made-to-order lengths beyond this range are manufactured to order. For multimode channels, keeping the cord close to the true path length additionally protects the optical loss budget, since each extra meter of 50/125µm glass adds attenuation at 850nm. Specifying the precise path length avoids the two the slack storage problem of an overlong cord and the strain risk of one that is too short.

Quality control and testing

Every cord is terminated with precision zirconia ferrule LC connectors and measured for insertion loss and return loss before packing; the 0.3dB ceiling is a verified test limit. End-face geometry is inspected for consistent physical contact, and ferrules are rated for up to one thousand mating cycles in frequently reconfigured patching fields.

Ordering and Factory Support

Reference against the LC-LC OM4 duplex armored series and state the path length and jacket rating. Non-standard colors, APC polish or alternative connectors are handled through the custom duplex armored program; send the need with the inquiry and the factory confirms the manufacturable specification prior to production. Our UAE project support can review the requirement with Shenzhen production before a formal quotation is issued.
