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

Singapore high-density designs should assess this item together with panel access, cable routing and the complete optical loss allowance. This duplex FTTA patch cable bridges this connector interface 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 active hardware, frames and enclosures that still present SC interfaces. This optical cable itself is the standard FTTA outdoor structure: 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 interfaces.

Why a hybrid LC to SC cord exists

Base station sites evolve in stages. A shelter upgraded with new baseband equipment presents LC ports; concurrently, 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 production-terminated LC and SC ends solves the transition cleanly. Because both connectors are polished and tested in the factory, the mixed interface adds no field termination and no extra 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 corresponding outdoor standard: a 7.0mm LSZH jacket with UV stabilization, aramid strength members, and helical steel armored branches over both tails. This optical 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 commonly 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 existing single-mode plant is unaffected; consequently, the hybrid cord drops into the installed link budget.

Planning the connector orientation

On a hybrid cord it is worth stating in a clear manner which end goes where: LC toward the baseband or radio port, SC toward the frame or enclosure. Marking both legs at the factory avoids crossed connections during commissioning, and the breakout lengths at each end may also be matched to the actual hardware positions so neither tail carries strain or excess slack.

Length choices and custom production

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

Quality assurance and factory 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 branch. End-face geometry is inspected on each optical connector, and the completed cord is checked as a whole product so it may also be plugged into service without on-site rework.

Quotation and Factory Support

Refer to the LC-SC duplex FTTA range during the request for a quotation and state the pathway length collectively with the correct connector orientation. Other connector mixes, including FC and ST, are covered by the custom duplex FTTA program on the corresponding outdoor platform; send the requirement with the enquiry and the factory will review the manufacturable specification before manufacturing begins. Singapore and regional project orders can be reviewed for interface compatibility, packing details and delivery coordination.
