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 pairs two LC UPC connectors on an OM3 50/125µm multimode unit protected by a helical stainless steel tube. The aqua 3.0mm riser-rated (OFCR) jacket keeps the cord flexible for cabinet and under-floor routing, and the steel armor inside takes the crush, pull and rodent exposure that would otherwise require metal conduit. Bend-insensitive OM3 glass holds attenuation steady around the tight turns of real cable pathways.

OM3 for 10G SR and legacy 40G links

OM3 remains the existing base for a huge share of enterprise multimode: it runs 10GBASE-SR to 300m and handles 40GBASE-SR4 over the in-row and in-room distances where those links were deployed. Where the installed link is OM3, adding an OM4 cord brings no measurable benefit, so matching the cord to the plant keeps the two cost and documentation clean. The duplex LC interface connects directly to SFP+ and QSFP breakout optics.

OM3 or OM4: choosing the right grade

The practical difference is modal bandwidth: OM4 extends 10G reach from 300m to 400m and gives 40/100G SR4 links more headroom. For new multimode builds, OM4 is normally the safer long-term option; for expansions of an OM3 plant, matching OM3 patch cords keep the inventory consistent. Because the two grades share this identical armored build, the mechanical protection is identical whichever optical grade the path calls for.

Armor protection in shared pathways

Multimode backbones frequently cross spaces that were never designed as cable routes: retail ceilings, plant rooms, temporary event cabling. In those environments the biggest threat is mechanical, not optical. Because the helical steel tube inside this cord wraps the buffered fibers directly, the connection survives foot traffic, moving hardware and rodent activity that would crush a standard jumper, and it does so without the cost and rigidity of conduit.

Mixed plants and clean documentation

Where OM3 and OM4 the two exist in one building, color alone will not keep the records straight, because the two use aqua. Label every cord with its grade at the two ends and keep the link records updated when links move. Because this series shares one build across grades, the mechanical behavior is identical and only the glass changes; that makes mixed-grade sites simpler to document than sites mixing armored and unarmored 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. Because each meter of multimode glass adds 850nm attenuation, ordering the cord at the actual path length is the simplest way to keep the link inside its optical loss budget. 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

Each assembly is terminated with precision zirconia ferrule connectors and verified for insertion loss and return loss before packing. The 0.3dB insertion loss figure is a tested limit, not a design target. Ferrule end faces are geometry-checked for consistent physical contact and rated for up to one thousand mating cycles.

Ordering and Factory Support

Refer to the LC-LC OM3 duplex armored series when ordering a quotation, and provide the path length and jacket rating. For other colors, polish types or connector mixes, the custom duplex armored program builds to the stated need once the factory confirms the specification. Our UAE project support can review the requirement with Shenzhen production before a formal quotation is issued.
