Distribution optical cable and trunk optical cable
Distribution cable: refers to the cable between the optical handover box and the optical distribution box, and generally uses a general outdoor type cable. In the ODN, Optical Cable is the lowest level of optical signal transmission infrastructure, which is divided into trunk optical cable, distribution optical cable and household optical cable. Instead of running 12 separate cables between two cabinets, you can run one trunk cable with 12. OptoTrunk Cables optimize space, simplify system architecture, improve performance and support expansion in data center applications. They enable future-proofed optical network design and provide more efficient connectivity than multiple single cables that have separate connectors. Although both are pre-terminated assemblies used to accelerate deployment, they differ in fiber structure, termination format, fan-out design, and system positioning. Misunderstanding the. In hyperscale data centers and enterprise networks, MTP/MPO fiber optic solutions have become the backbone of high-speed connectivity.
