LC to SC Duplex FTTA Outdoor Patch Cable, OS2, 7.0mm LSZH

This duplex FTTA patch cable bridges the connector 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, frames and enclosures that still present SC interfaces. The cable 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 both ends.

Base station sites evolve in stages. A shelter upgraded with new baseband equipment presents LC ports, while 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-terminated LC and SC ends solves the transition cleanly. Both connectors are polished and tested in the factory, so the mixed interface adds no field termination and no additional loss beyond the rated 0.3dB per connector.

Whether the SC end lands in an outdoor cabinet or the LC end climbs to the radio, the entire 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 both tails. The 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.

Enclosures that accept SC connectors are often 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, so the hybrid cord drops into the existing loss budget.

On a hybrid cord it is worth stating clearly 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 can be matched to the actual hardware positions so neither tail carries strain or excess slack.

Standard lengths 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. Custom lengths beyond this range are manufactured to order. For mixed-equipment sites, record which end of the route is LC and which is SC together with the length; the orientation is built into the assembly and cannot be reversed in the field. Specifying the exact route length avoids both the slack storage problem of an overlong cord and the strain risk of one that is too short.

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 leg. End-face geometry is inspected on every connector, and the completed cord is checked as a whole assembly so it can be plugged into service without on-site rework.

Refer to the LC-SC duplex FTTA family when requesting a quotation and state the route length together with the required connector orientation. Other connector mixes, including FC and ST, are covered by the customized duplex FTTA program on the same outdoor platform; send the requirement with the enquiry and the factory will confirm the manufacturable specification before production.
