What is a Pre-connectorized ODN?
A Pre-connectorized Optical Distribution Network (ODN) is a next-generation fiber optic deployment model designed to eliminate on-site fiber splicing by leveraging factory-assembled, ready-to-use fiber cables and distribution boxes. The entire system supports plug-and-play architecture, allowing rapid deployment of fiber infrastructure from the central office all the way to the subscriber's premise.
Pre-connectorized ODNs are especially suited for FTTH (Fiber to the Home) projects, enabling: Shorter installation time, Fewer skilled technicians, Lower labor and maintenance costs , Minimal field failures due to factory-tested terminations
Challenges in Traditional ODN Deployments
Despite widespread use, traditional ODN systems present multiple limitations:
High Failure Rate in Field Connections
Manual splicing and frequent exposure of connectors during installation or maintenance can lead to contamination, misalignment, and UV/moisture-induced degradation, increasing signal loss and downtime.
Low Deployment Efficiency
Conventional field splicing involves multiple fusion joints per fiber drop, making the process labor-intensive, slow, and error-prone. Parallel deployment is difficult.
High Technical Requirements
Fusion splicing demands expensive equipment and certified personnel. This adds training costs, complicates workforce management, and slows down large-scale rollouts.
Key Technologies in Pre-connectorized ODN
Factory Pre-terminated Fiber Cables
All drop and feeder cables are pre-assembled with SC/APC connectors in a controlled environment. This guarantees insertion loss ≤0.3dB and return loss ≥60dB. Common outer jackets are LSZH or HDPE, and connector ends include:
Waterproof Mini-SC (IP68)
Hardened SC/APC
MPO/MTP (up to 12 fibers)
Cable diameter options: 2.0mm, 2.0×3.0mm, 2.0×5.0mm, 4.0×7.0mm, flat drop, or round OSP cables. OEM customization is supported.
Unequal Ratio Splitters
Asymmetrical 1x2 splitters (e.g., 70/30) enable cascaded or tree-style topologies, simplifying the use of single-fiber links instead of bundles. These help extend ODN reach and minimize cabling bulk.
Fully Sealed Protection
All connectorized products meet IP67/IP68 standards, ensuring resistance against UV, dust, water, acid/alkali, and extreme temperatures. Durable housings and sealing rings ensure reliable operation in outdoor environments.
