In the case of building network connectivity between two structures, within a large building, or connecting networks from the cabinet of the third-party Internet service provider (ISP) to your home, optical fiber cable is used in order to meet the requirements of bandwidth,Marker Ties distance and noise. Outdoor fiber optic cable is good for outdoor cabling but not suitable for indoor applications. At the meantime, ordinary indoor fiber optic cable is not designed for outdoor cabling. Only indoor/outdoor fiber cables can be used for connecting networks of two buildings, inside the building and in the entrance facilities as well. Pulling-eye pre-terminated fiber optic cable assemblies are designed for such environments.
Pulling Eye Pre-terminated Indoor/Outdoor Multifiber Cable

As its name indicates, this pre-terminated fiber optic cable is suitable for both indoor and outdoor cabling. Such multifiber pre-terminated fiber cable assemblies are designed with pulling eyes, which can be used with 2 to 24 fiber cables. The outer jackets of pulling eye pre-terminated indoor/outdoor multifiber cables are typically indoor/outdoor plenum (OFNP), polyolefine flame retardant (LSZH) or polyethylene (PE).

There are several key features of the pulling eye pre-terminated fiber cables that make them preferable for indoor/outdoor installations.

The first feature is that these cables are pre-terminated, which means the procedures of stripping the cables, preparing the epoxy, applying the connector, scribe and polishing, inspecting and testing are all done on the manufacturer’s side. One of the main advantages for specifying pre-terminated fiber optic cables is that the controlled factory processes with pre-termination results in superior performance. Consistent, high quality connector end-face geometry results in lower insertion loss and better end-to-end attenuation in the system.

The second characteristic of these pre-terminated cables is the pulling eye. It further speeds up the installation process compared with filed termination. Pre-terminated fiber optic cable has omitted the time needed for termination, and the pulling eye saves time during installation of conduits, ducts or risers. In addition, the pulling eye protects the connectors of the indoor/outdoor fiber optic cables and prevents the cables from twisting during the installation process. Since the pulling eye is strain relived directly onto the outer jacket, it ensures that the pulling stress and strain do not act on the core or the terminations. It allows a tension up to 245N.
