For Nigerian deployments, this product should be evaluated as part of the complete network path, including its connectors, mapping and acceptance values. This duplex FTTA patch cable bridges the interface connector gap between generations of base station hardware: LC UPC duplex on one end for the small-form-factor ports on current baseband units and radios, SC UPC duplex on the other for the network equipment, frames and enclosures that still present SC interfaces. The cable assembly itself is the standard FTTA outdoor construction: two OS2 9/125µm single-mode fibers of Corning G.657.A1 glass in a 7.0mm LSZH jacket, with helical steel armored branches protecting the tails at the two cable ends.

Why a hybrid LC to SC cord exists
Base station sites evolve in stages. A shelter upgraded with new baseband hardware presents LC ports; at the same time, the outdoor enclosure, the fiber distribution frame or the surviving radio hardware may still be SC. Replacing each SC interface is rarely economical; a hybrid jumper with assembled at the factory LC and SC ends solves the transition cleanly. The two connectors are polished and tested in the factory, which means the mixed interface adds no field termination and no added loss beyond the rated 0.3dB per connector.
Outdoor construction for the whole route
Whether the SC end lands in an outdoor cabinet or the LC end climbs to the radio, the full cord is built to the same outdoor standard: a 7.0mm LSZH jacket with UV stabilization, aramid strength members, and helical steel armored branches over the two tails. The completed product tolerates vertical hanging runs, wind-induced flexing and the temperature swings of an exposed structure, with an operating range from -20 to 70 degrees Celsius.
Bend-insensitive glass at both ends
Enclosures that accept SC connectors are often older and tighter inside than modern hardware. G.657.A1 fiber tolerates the 10D static bends that appear when a duplex cord is dressed into a crowded box, holding attenuation steady where legacy G.652.D glass would begin to leak light. Compatibility with the fitted single-mode plant is unaffected, which means the hybrid cord drops into the established link loss calculation.
Planning the connector orientation
On a hybrid cord it is worth stating distinctly which end goes where: LC toward the baseband or radio port, SC toward the frame or enclosure. Labelling the two legs at the factory avoids crossed connections during commissioning, and the breakout lengths at every end can readily be matched to the actual hardware positions so neither tail carries strain or excess slack.
Stock lengths and made-to-order sizes
Stock length choices are stocked for fast delivery: 3m (10ft), 5m (16ft), 10m (33ft), 20m (66ft), 30m (98ft) and 50m (164ft), covering the common shelter-to-tower and frame-to-radio runs this cord is built for. Customized lengths beyond this range are manufactured to order. For mixed-hardware sites, record which end of the route is LC and which is SC together with the length; the orientation is built into the completed product and cannot be reversed in the field. 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
The two the LC and the SC terminations are factory polished and optically tested: insertion loss is verified against the 0.3dB ceiling and return loss against the 50dB minimum on every breakout leg. End-face geometry is inspected on every optical connector, and the completed cord is checked as a whole assembly so it can readily be plugged into service without on-site rework.
Ordering Information and Support
Refer to the LC-SC duplex FTTA family at the request stage a quotation and state the route length together with the needed connector orientation. Other connector mixes, including FC and ST, are covered by the made-to-order duplex FTTA program on the same outdoor platform; send the requirement with the enquiry and the factory will establish the manufacturable specification before the build starts. For Nigerian orders, our team can check the requirement before coordinating manufacture and international delivery.
