10/100BASE-T SFPLC to SC Duplex FTTA Outdoor Patch Cable, OS2, 7.0mm LSZH
New Zealand engineering teams can use the documented values below to compare the product with the intended channel and as-built requirements. This duplex FTTA patch cable bridges the relevant 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 relevant equipment, frames and enclosures that still present SC interfaces. The relevant cable itself is the standard FTTA outdoor design: 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 connection points.

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 factory-finished LC and SC ends solves the transition cleanly. Because the two connectors are polished and tested in the factory, 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 complete cord is built to the matching outdoor standard: a 7.0mm LSZH jacket with UV stabilization, aramid strength members, and helical steel armored branches over the two tails. This manufactured 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 typically 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; therefore, the hybrid cord drops into the established loss calculation.
Planning the connector orientation
On a hybrid cord it is worth stating in clear terms which end goes where: LC toward the baseband or radio port, SC toward the frame or enclosure. Identification the two legs at the factory avoids crossed connections during commissioning, and the breakout lengths at every end can be matched to the actual hardware positions so neither tail carries strain or excess slack.
Length range and customization
Regular length versions 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. Project-built lengths beyond this range are manufactured to order. For mixed-hardware sites, record which end of the channel is LC and which is SC as one system with the length; the orientation is built into this manufactured assembly and cannot be reversed in the field. Specifying the particular channel length avoids the two the slack storage problem of an overlong cord and the strain risk of one that is too short.
Optical testing and quality checks
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 each individual branch. End-face geometry is inspected on each relevant connector, and the completed cord is checked as a whole item so it can be plugged into service without on-site rework.
How to Specify and Order
Refer to the LC-SC duplex FTTA product line when requisitioning a quotation and state the channel length as one system with the intended connector orientation. Other connector mixes, including FC and ST, are covered by the made-to-order duplex FTTA program on the matching outdoor platform; send the requirement with the enquiry and the factory will cross-check the manufacturable specification before production is released. New Zealand project orders can include documentation and labeling requirements alongside the technical configuration.
