SC to SC Duplex Armored Fiber Patch Cable, OM4, Riser (OFCR)
For Tanzanian site work, correct product selection should be followed by careful transport, connector inspection and retention of the fiber records. This duplex armored patch cable fits SC UPC connectors on both connector ends of an OM4 50/125µm multimode unit, with a helical stainless steel tube protecting the fibers under the aqua 3.0mm riser-rated (OFCR) jacket. It is built for installations where SC interfaces remain on the panels and hardware but the pathway demands real mechanical protection: open ceilings, industrial floors and shared risers.

SC duplex interfaces in panel and legacy environments
SC connectors remain common on wall-mounted enclosures, older fiber distribution frames, media converters and industrial Ethernet gear. The push-pull latching body tolerates frequent handling and is easy to seat with gloved hands, which is part of why SC persists in field-side cabling. This cord keeps that familiar interface while adding the steel armor those exposed environments normally demand.
OM4 bandwidth for short-reach optics
Behind the SC bodies the glass is full OM4: 10GBASE-SR to 400m, with headroom for 40G and 100G short-reach optics at row and room distances. For buildings that standardized on SC panels years ago, this makes it possible to upgrade connection speeds without re-terminating the fixed plant, as long as the link stays within the OM4 distance envelope.
Steel armor for exposed routing
SC-terminated links are frequently found exactly where cables get hurt: factory floors, campus outbuildings, temporary runs at events and build sites. Because the helical stainless tube inside the jacket wraps the buffered fibers directly, the cord shrugs off crushing under floor tiles, accidental pulls and rodent damage. Technicians can cross areas that would otherwise call for conduit, keeping the path small and easy to change later.
Care of SC connectors in the field
SC ferrules are 2.5mm and easy to examine with standard tips and microscopes. clean both end faces with a dry cassette cleaner and examine if the connection margin is tight; most "bad cord" reports in the field trace back to contamination rather than damage before plugging in. The push-pull housing should click positively; if it does not automatically, look at for dust caps left in the optical adapter rather than forcing the latch.
Standard lengths plus custom builds
Standard offerings 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. Bespoke lengths beyond this range are manufactured to order. Matching the cord length to the actual path keeps slack out of the rack-mounted panel and preserves the 850nm optical link budget on longer multimode runs. Specifying the precise path length avoids both the slack storage problem of an overlong cord and the strain risk of one that is too short.
Factory quality control and testing
Each SC-terminated unit is built with precision zirconia ferrules and tested for insertion loss and return loss before packing; the 0.3dB ceiling is verified on every cord. End-face geometry is checked for stable physical contact across repeat matings, and the SC housings are latch-tested for positive engagement.
Purchase and Factory Support
Quote against the SC-SC OM4 duplex armored series with the path length and jacket rating stated. Other connector mixes, polish types and jacket colors are supplied through the customized duplex armored program once the factory confirms the requested specification. For Tanzanian deliveries, the order details should include any site identification needed by the installation team.
