Custom 6-Fiber Armored Fiber Patch Cable, OS2, LC/SC/FC/ST
For Tanzanian site work, correct product selection should be followed by careful transport, connector inspection and retention of the fiber records. This configured-to-order unit puts six OS2 9/125µm G.657.A1 fibers in a single armored 4.5mm round trunk, breaking out to six individual 3.0mm legs terminated with any mix of LC, SC, FC or ST connectors in UPC or APC polish. One pull replaces three separate duplex patch cords, and the helical stainless steel armor protects the whole group along routes where separate jumpers would each need protection.
Product Highlights
- Three duplex circuits or six simplex legs per assembly
- LC, SC, FC or ST connectors in any leg mix, UPC or APC
- Riser (OFCR), LSZH or plenum (OFNP) jacket options
- 0.3m or 0.5m breakout legs in 3.0mm armored sub-units
- 200/400N tensile rating for trunk pulls
- 6 fibers OS2 9/125µm in one armored 4.5mm trunk

Six fibers in a single armored round cable
Three duplex links normally mean three separate patch cords competing for space in the identical tray. This optical assembly consolidates them into one 4.5mm armored trunk with six fibers, which pulls faster, dresses cleaner and presents only one cable to every pathway pinch point. At the far end the installed trunk fans out into individual legs that land exactly where three separate patch cords would have.
Breakout design and leg options
The branch point is supplied with 0.3m or 0.5m legs in 3.0mm armored sub-units, each terminated with LC, SC, FC or ST connectors as the job requires. Legs may generally be mixed, for example LC toward the switch and SC toward the rack-mounted panel, and each of the legs is labeled so the three circuits stay identifiable after commissioning.
Reducing cable count in congested pathways
Tray fill, sleeve capacity and bend space are the limits that actually stop retrofits. Replacing three patch cords with one trunk cuts the supplied cable count by two thirds on that path, and the 200/400N tensile rating lets the single trunk tolerate the pull that three loose patch cords never would. For riser, LSZH or plenum zones the jacket is matched to the building section.
Labeling and circuit management
With six fibers in one trunk, identification is part of the build, not an afterthought. Legs are labeled at both connector ends, and the labeling scheme can observe the customer document: circuit numbers, room codes or port references. For phased rollouts the identical scheme repeats on every batch; thus, a technician picking up the installation in month six reads the patch cords exactly as the first crew left them.
Trunk construction in detail
Inside the 4.5mm jacket the six tight-buffered fibers are stranded around a central strength member, wrapped in aramid yarn and then in the helical stainless tube, with the outer compound extruded over the armor. That layering is what allows a 200N long-term pull rating in a trunk this thin. The breakout point is potted and strain-relieved so the transition from trunk to legs carries no load into the ferrules. For Tanzanian site work, keep this requirement with the field checklist and the delivered product records.
Standard lengths plus custom builds
Trunk lengths observe the standard stocked range: 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 10m (33ft), 15m (49ft), 20m (66ft) and 30m (98ft), with other lengths built to order. State the breakout length and leg labeling scheme with the request so the branch point lands correctly at both connector ends.
Factory quality control and testing
Every leg of every supplied assembly is terminated with precision zirconia ferrules and measured for insertion loss and return loss before packing; the 0.3dB ceiling and polish-appropriate return figures are verified per fiber, not per batch sample. The branch point point is strain-relieved and the whole unit is pull-tested to its rated load.
Purchase and Factory Support
Send the leg connector mix and polish, the jacket rating, trunk length and breakout length. The factory confirms the setup diagram with the quotation; marking needs for the three circuits may generally be added to the identical diagram. For Tanzanian deliveries, the order details should include any site identification needed by the installation team.
