Custom Process for 1310nm Fiber Optic Cables in FTTH

Custom 1310nm fiber optic cables for FTTH are designed, manufactured, and pre-terminated to ensure low loss, high reliability, and easy deployment in residential networks.

Fiber Selection and Design

For FTTH applications, single-mode fibers optimized for 1310nm wavelength are typically used due to their low attenuation and long-distance transmission capabilities. Customization begins with selecting the fiber type (e.g., G.652 or G.657), core/cladding specifications, and jacket material (PE, PVC, or LSZH) based on environmental conditions and installation requirements . Color-coded sheaths or fiber stripes can be added for easy identification during deployment .

Pre-Termination and Connectorization

Pre-terminated fiber assemblies are factory-assembled and polished, ready for plug-and-play installation. This process eliminates on-site splicing, reduces labor, and ensures consistent low insertion loss and high return loss performance . Common connector types include LC, SC, ST, and MTP/MPO, and assemblies can be customized for simplex, duplex, or breakout configurations . Optional pulling eyes or protective boots can be added to facilitate installation in ducts or conduits.

Quality Assurance and Testing

Custom 1310nm FTTH cables undergo factory testing to verify optical performance, including insertion loss, return loss, and continuity. This ensures that each cable meets the required standards for residential deployment and minimizes troubleshooting during installation . Environmental testing may also be performed to confirm durability across temperature ranges and mechanical stress.

Installation Considerations

During FTTH deployment, careful planning of cabling routes is essential. Fibers should avoid sharp bends, excessive tension, and parallel runs with power lines to prevent signal degradation . Both surface-mounted and concealed installations are possible, depending on aesthetic and structural requirements. Fusion splicing or mechanical connectors may be used for final terminations at the Optical Network Terminal (ONT) in the subscriber's home .

Custom Manufacturing Options

Manufacturers like HOC and Huihong Technologies offer tailored production for FTTH projects, including small trial orders or large-scale deployments. Custom options include fiber count, cable structure (unitube, MLT), jacket type, and pre-terminated lengths to match specific project needs . This flexibility allows network operators to optimize cost, installation efficiency, and network performance.

Summary

The custom process for 1310nm FTTH fiber optic cables involves fiber selection, pre-termination, connectorization, rigorous testing, and careful installation planning. By leveraging factory-assembled, pre-tested cables, FTTH deployments achieve faster installation, lower labor costs, and reliable high-speed connectivity for residential users .
