UltraL™ Fiber Connectors/Patch Cables

The UltraL™ (Ultra-low-loss) connectors/patch cables uniquely achieve exceptionally low coupling loss <0.07dB for single-mode SMA 28 fibres and <0.01dB for multimode fibres. Conventional fibre optical connectors intrinsically have core misalignment due to production tolerances, resulting in typical loss ~ 0.30dB for SM28 fibre and higher loss for smaller core fibres, as shown by the diagram. The patent pending breakthrough technology overcomes this drawback by performing active core alignment and laser welding with submicron precision, enabling the next generation optical systems, including short-wavelength sensor systems, quantum systems, data centres with large fibre cable connections and higher bandwidth networks of longer spans. The connector formats are compatible with standard connectors and can be repolished to remove surface scratches after extended uses.

Various Fibre Types

FC/PC is the default connector type of UltraL™, while other connector types can be specially made. The ultra-low loss performance requires mating between UltraL™ connectors, although it mates with regular connectors without the benefit of ultra-loss. The UltraL™ can be cost-effectively produced in volume. Furthermore, due to near-perfect core mating between the UltraL™ pair, the return loss is also improved > 55dB, eliminating the need for angle connectors that typically have higher optical losses. PM UltraL™ connectors can also be made.
