LC to LC Simplex FTTA Outdoor Patch Cable, OS2, 7.0mm LSZH

This simplex FTTA patch cable carries a single OS2 9/125µm single-mode fiber from the baseband equipment to the radio unit, matching the single-fiber optics now common on tower-top radio units. It uses the same 7.0mm LSZH outdoor construction as the duplex FTTA family: Corning G.657.A1 bend-insensitive glass under a UV-stabilized jacket, with a helical steel armored branch protecting the exposed section at each end. The LC UPC interfaces plug directly into BiDi and single-fiber SFP modules used in LTE and 5G radio systems.

A growing share of radio units use bidirectional optics that run transmit and receive on one strand. A simplex jumper matches that architecture exactly: one fiber, one connector at each end, no dark strand coiled behind the radio. Using a simplex cord instead of a duplex with one leg parked reduces weight on the tower, simplifies port mapping and removes the risk of a dangling unterminated leg collecting moisture or damage.

The exposed ends of an FTTA run take the real abuse: clamp pressure at the cable entry, vibration from the structure, and wildlife along the route. The helical steel armored branch on this jumper absorbs that exposure while staying flexible enough to dress through glands and narrow tray entries. Because the armor is built into the branch rather than added on site, the protection is consistent from the first meter to the connector boot.

Junction boxes at the tower base and the cable entry at the RRU shroud leave little room for generous bends. G.657.A1 glass keeps attenuation stable at a 10D static bend radius, so the jumper can be dressed into the available space without eating into the loss budget. The fiber remains fully compatible with installed G.652.D feeder plant, so the simplex jumper integrates into existing single-mode infrastructure without re-engineering the link.

Because the route usually begins inside a shelter or cabinet and ends outdoors, the LSZH jacket is specified for both environments: low smoke and halogen-free behavior for indoor sections, UV and chemical resistance for the outdoor climb. A single continuous jacket means no transition hardware and one less potential failure point between the baseband equipment and the radio.

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. On single-fiber links the jumper length directly sets the slack stored at the RRU shroud; ordering the measured length keeps the installation clean and avoids a heavy service loop hanging from the radio unit. 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.

Each simplex assembly is terminated with precision zirconia ferrule LC connectors and optically tested before packing. Insertion loss is verified against the 0.3dB ceiling and return loss against the 50dB minimum on every cord, and end-face geometry is inspected so the physical contact stays consistent across repeated mating during commissioning and maintenance.

Refer to the LC-LC simplex FTTA family when requesting a quotation and state the route length. Where the radio or the baseband side uses SC instead of LC, or where a non-standard breakout is needed at one end, the customized simplex FTTA program covers the same outdoor platform; send the requirement with the enquiry and the factory confirms the build before production.
