LC to SC Duplex FTTA Outdoor Patch Cable, OS2, 7.0mm LSZH
For Tanzanian site work, correct product selection should be followed by careful transport, connector inspection and retention of the fiber records. This duplex FTTA patch cable bridges the connector being used gap between generations of base station equipment: 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 equipment being used, frames and enclosures that still present SC interfaces. The supplied cable itself is the standard FTTA outdoor build: 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 both connector ends.

Why a hybrid LC to SC cord exists
Base station sites evolve in stages. A shelter upgraded with new baseband equipment presents LC ports, whereas the outdoor enclosure, the fiber distribution frame or the surviving radio hardware may still be SC. Replacing every SC interface is rarely economical; a hybrid jumper with factory-assembled LC and SC ends solves the transition cleanly. Both connectors are polished and tested in the factory; thus, the mixed interface adds no field termination and no additional 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 entire cord is built to the identical outdoor standard: a 7.0mm LSZH jacket with UV stabilization, aramid strength members, and helical steel armored branches over both tails. The supplied assembly 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 frequently older and tighter inside than modern equipment. 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 installed single-mode plant is unaffected; thus, the hybrid cord drops into the existing optical link budget.
Planning the connector orientation
On a hybrid cord it is worth stating visibly which end goes where: LC toward the baseband or radio port, SC toward the frame or enclosure. Labeling both legs at the factory avoids crossed connections during commissioning, and the breakout lengths at each end may generally be matched to the actual hardware positions so neither tail carries strain or excess slack.
Standard lengths plus custom builds
Standard offerings 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. Bespoke lengths beyond this range are manufactured to order. For mixed-equipment sites, record which end of the path is LC and which is SC jointly with the length; the orientation is built into the supplied assembly and cannot be reversed in the field. 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
Both 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 each of the legs. End-face geometry is inspected on every connector used, and the completed cord is checked as a whole unit so it may generally be plugged into service without on-site rework.
Purchase and Factory Support
Refer to the LC-SC duplex FTTA series when purchasing a quotation and state the path length jointly with the requested connector orientation. Other connector mixes, including FC and ST, are covered by the customized duplex FTTA program on the identical outdoor platform; send the specification with the request and the factory will ensure the manufacturable specification before fabrication. For Tanzanian deliveries, the order details should include any site identification needed by the installation team.
