Custom Pre Terminated Fiber Assemblies - Factory Supplier
Custom pre terminated fiber assemblies are engineered fiber optic cable solutions that arrive fully prepared for immediate deployment, eliminating on-site splicing and connector installation time. As a factory-direct supplier, we manufacture these assemblies to exact project specifications, serving critical roles in data centers, telecommunications infrastructure, enterprise networks, and industrial automation systems. Each assembly undergoes rigorous end-face inspection and insertion loss testing, ensuring optical performance that meets or exceeds industry benchmarks. Our production facility operates under ISO 9001 quality management protocols, allowing us to deliver consistent, repeatable results across high-volume orders. Whether you require simplex, duplex, or multi-fiber trunk configurations, our engineering team works directly with clients to define fiber count, connector type, polarity, cable jacket rating, and overall assembly length — delivering a plug-and-play solution that accelerates installation schedules and reduces total project cost.
What is Custom Pre Terminated Fiber Assemblies?
Custom pre terminated fiber assemblies are factory-built fiber optic cable units fitted with pre-installed, factory-polished connectors at one or both ends. Unlike field-terminated alternatives, these assemblies are precision-manufactured under controlled conditions, achieving typical insertion loss values of ≤0.3 dB per mating and return loss ≥50 dB (UPC) or ≥60 dB (APC), ready for direct installation into patch panels, transceivers, or distribution frames.

Custom Pre Terminated Fiber Assemblies Manufacturing Process
Production begins with selecting premium grade optical fiber — single-mode OS2 (ITU-T G.652.D) or multimode OM3/OM4/OM5 — followed by precision cable cutting to customer-specified lengths with a tolerance of ±0.5%. Connectors are epoxy-bonded and machine-polished through a multi-stage lapping process. Every completed assembly is 100% tested on a calibrated optical loss test set (OLTS) per IEC 61300-3-4 standards before packaging and shipment.
Custom Pre Terminated Fiber Assemblies Technical Specifications
Our assemblies support a broad specification range to match diverse network requirements. Standard offerings include LC, SC, ST, FC, MPO/MTP connector interfaces in UPC or APC polish. Fiber types span OS1, OS2, OM1 through OM5. Operating wavelengths cover 850 nm, 1310 nm, and 1550 nm bands. Cable outer diameters range from 0.9 mm (simplex) to 7.0 mm (armored duplex). Minimum bend radius is 30 mm under load, and assemblies are rated for operating temperatures from -20°C to +70°C, with plenum (OFNP) and riser (OFNR) jacket options available.
