LC to LC Simplex FTTA Outdoor Patch Cable, OS2, 7.0mm LSZH
For Pakistani procurement and engineering teams, the specification provides a practical basis for checking compatibility before production is requested. This simplex FTTA patch cable carries a single OS2 9/125µm single-mode fiber from the baseband hardware to the radio unit, matching the single-fiber optics now common on tower-top radio units. It uses the identical 7.0mm LSZH outdoor build as the duplex FTTA series: Corning G.657.A1 bend-insensitive glass under an UV-stabilized jacket, with a helical steel armored branch protecting the exposed section at every end. The LC UPC interfaces plug directly into BiDi and single-fiber SFP modules used in LTE and 5G radio systems.

Single-fiber links on modern towers
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 every 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 layout and removes the risk of a dangling unterminated leg collecting moisture or damage.
Mechanical protection where it counts
The exposed ends of an FTTA run take the real abuse: clamp pressure at the installed cable entry, vibration from the structure, and wildlife along the path. The helical steel armored branch on this jumper absorbs that exposure while staying flexible sufficient 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 optical interface boot.
Bend tolerance for congested enclosures
Junction boxes at the tower base and the installed cable entry at the RRU shroud leave little room for generous bends. Because G.657.A1 glass keeps attenuation stable at a 10D static bend radius, the optical jumper can also be dressed into the offered space without eating into the power budget. The fiber remains fully compatible with current G.652.D feeder plant, and therefore the simplex jumper integrates into present single-mode infrastructure without re-engineering the connection.
One jacket from shelter to antenna
Because the path normally begins inside a shelter or cabinet and ends outdoors, the LSZH jacket is specified for the two 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 hardware and the radio.
Standard and custom length options
Catalogue 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. Special lengths beyond this range are manufactured to order. On single-fiber links the optical 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 precise path length avoids the two the slack storage problem of an overlong cord and the strain risk of one that is too short.
Test standards and quality control
Every simplex unit 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 each cord, and end-face geometry is inspected so the physical contact stays consistent across repeated mating during commissioning and servicing.
Ordering Details and Factory Support
Refer to the LC-LC simplex FTTA series when specifying a quotation and state the path 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 custom-built simplex FTTA program covers the identical outdoor platform; send the specification with the request and the factory confirms the build before factory assembly. For Pakistan, a clear port or maintenance schedule helps us confirm the correct factory-built configuration before supply.
