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

Malaysian upgrade projects can use this configuration where its interface and fiber map align with both the installed cabling and the new hardware. This duplex FTTA patch cable bridges the mating 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 connected hardware, frames and enclosures that still present SC interfaces. The completed 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 the two terminations.

Why a hybrid LC to SC cord exists

Base station sites evolve in stages. While the outdoor enclosure, the fiber distribution frame or the surviving radio hardware may still be SC, a shelter upgraded with new baseband hardware presents LC ports. Replacing each SC interface is rarely economical; a hybrid jumper with factory-completed LC and SC ends solves the transition cleanly. The two connectors are polished and tested in the factory, meaning that the mixed interface adds no field termination and no further 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 finished 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 deployed single-mode plant is unaffected, meaning that the hybrid cord drops into the current channel loss calculation.

Planning the connector orientation

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

Available lengths and custom orders

Normal length options 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 cable 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 finished 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.

Testing and inspection practice

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

Ordering and Customization Support

Refer to the LC-SC duplex FTTA family when seeking a quotation and state the route length together with the appropriate connector orientation. Other connector mixes, including FC and ST, are covered by the project-specific duplex FTTA program on the same outdoor platform; send the need with the inquiry and the factory will determine the manufacturable specification before the product is built. For Malaysian upgrades, our team can compare the requested build with the existing environment before production begins.
