For Nigerian deployments, this product should be evaluated as part of the complete network path, including its connectors, mapping and acceptance values. This duplex armored patch cable pairs two LC UPC connectors on an OM3 50/125µm multimode assembly 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. For Nigerian deployments, retaining this detail with the acceptance records supports consistent maintenance.

OM3 for 10G SR and legacy 40G links
OM3 remains the fitted 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 established channel is OM3, adding an OM4 cord brings no measurable benefit, which means 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 usually the safer long-term choice; for expansions of an OM3 plant, matching OM3 cords keep the inventory consistent. The two grades share this same armored construction, which means the mechanical protection is identical whichever optical grade the route 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. The helical steel tube inside this cord wraps the buffered fibers directly, which means the link 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, as the two use aqua. Label every cord with its grade at the two cable ends and keep the channel records updated when links move. This family shares one construction across grades, which means the mechanical behavior is identical and only the glass changes; that makes mixed-grade sites simpler to document than sites mixing armored and unarmored cords.
Stock lengths and made-to-order sizes
Stock length choices 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. Customized lengths beyond this range are manufactured to order. Because each meter of multimode glass adds 850nm attenuation, ordering the cord at the actual route length is the simplest way to keep the channel inside its link loss calculation. Specifying the exact route length avoids the two the slack storage problem of an overlong cord and the strain risk of one that is too short.
Inspection and test procedures
Every cable 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 uniform physical contact and rated for up to one thousand mating cycles.
Ordering Information and Support
Refer to the LC-LC OM3 duplex armored family at the request stage a quotation, and supply the route length and jacket rating. For other colors, polish types or connector mixes, the made-to-order duplex armored program builds to the stated requirement once the factory confirms the specification. For Nigerian orders, our team can check the requirement before coordinating manufacture and international delivery.
