LC to LC Simplex 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 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 corresponding 7.0mm LSZH outdoor structure as the duplex FTTA range: Corning G.657.A1 bend-insensitive glass under an 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.

Specifications

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 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 map 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 this optical cable entry, vibration from the structure, and wildlife along the pathway. The helical steel armored branch on this jumper absorbs that exposure while staying flexible ample 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 this connector interface boot.

Bend tolerance for congested enclosures

Junction boxes at the tower base and this optical 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; consequently, the completed jumper may also be dressed into the obtainable space without eating into the link budget. The fiber remains fully compatible with existing G.652.D feeder plant; consequently, the simplex jumper integrates into installed single-mode infrastructure without re-engineering the channel.

One jacket from shelter to antenna

Because the pathway generally 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.

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

Each simplex product 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 upkeep.

Quotation and Factory Support

Refer to the LC-LC simplex FTTA range during the request for a quotation and state the pathway 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 simplex FTTA program covers the corresponding outdoor platform; send the requirement with the enquiry and the factory confirms the build before manufacturing begins. Singapore and regional project orders can be reviewed for interface compatibility, packing details and delivery coordination.
