LC to LC Simplex 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 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 matching 7.0mm LSZH outdoor design as the duplex FTTA product line: 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 allocation 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 relevant cable entry, vibration from the structure, and wildlife along the channel. The helical steel armored branch on this jumper absorbs that exposure while staying flexible adequate 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 relevant connector boot.

Bend tolerance for congested enclosures

Junction boxes at the tower base and the relevant 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; therefore, the relevant jumper can be dressed into the offered space without eating into the loss calculation. The fiber remains fully compatible with fitted G.652.D feeder plant; therefore, the simplex jumper integrates into established single-mode infrastructure without re-engineering the optical path.

One jacket from shelter to antenna

Because the channel typically 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.

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. On single-fiber links the relevant 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 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

Every simplex item 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 service work.

How to Specify and Order

Refer to the LC-LC simplex FTTA product line when requisitioning a quotation and state the channel 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 made-to-order simplex FTTA program covers the matching outdoor platform; send the requirement with the enquiry and the factory confirms the build before production is released. New Zealand project orders can include documentation and labeling requirements alongside the technical configuration.
