Kenyan network installers should begin with the actual mating interfaces and site fiber records before assigning this product to a link. This duplex armored patch cable pairs two LC UPC connectors on an OM3 50/125µm multimode product 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 deployed 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. Because where the current path is OM3, adding an OM4 cord brings no measurable benefit, matching the cord to the plant keeps both 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 generally the safer long-term selection; for expansions of an OM3 plant, matching OM3 leads keep the inventory consistent. Both grades share this matching armored structure; therefore, the mechanical protection is identical whichever optical grade the pathway 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; therefore, the channel survives foot traffic, moving equipment 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
Since both use aqua, where OM3 and OM4 both exist in one building, color alone will not keep the records straight,. Label each cord with its grade at both connector ends and keep the path records updated when links move. This range shares one structure across grades; therefore, the mechanical behavior is identical and only the glass changes; that makes mixed-grade sites simpler to document than sites mixing armored and unarmored leads.
Standard lengths and custom builds
Regular lengths 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. Project-specific lengths beyond this range are manufactured to order. Because every meter of multimode glass adds 850nm attenuation, ordering the cord at the actual pathway length is the simplest way to keep the path inside its channel budget. Specifying the specific pathway length avoids both the slack storage problem of an overlong cord and the strain risk of one that is too short.
Factory testing and quality checks
Every 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 reproducible physical contact and rated for up to one thousand mating cycles.
How to Order and Factory Support
Refer to the LC-LC OM3 duplex armored range when asking for a quotation, and list the pathway length and jacket rating. For other colors, polish types or connector mixes, the project-specific duplex armored program builds to the stated specification once the factory confirms the specification. Project support for Kenya and East Africa is available to reconcile the ordered configuration with the intended installation.
