Multimode indoor fiber optic cables, such as OM3, use a larger core and support high-bandwidth data, audio, and video links, including 10 Gbps transmission up to 1,000 feet in the listed cable options. Single-mode OS2 cables use a smaller core for longer-reach backbone and service-provider links, so choose the fiber type that matches your equipment, connector style, transmission distance, and installation requirements.

For pathways, ducts, and environmental air spaces, choose an indoor fiber optic cable with a plenum-rated jacket and an OFNP listing, such as duplex OS2 or OM3 construction. A zip-cord design can help separate the fiber strands during installation, but confirm the cable listing and installation method meet applicable code requirements.

Select the connector configuration by matching the port on each device: use LC-LC or SC-SC for like-to-like connections, or LC-SC when the equipment uses different connector types. Also match the cable to the fiber type, such as multimode OM3 or single mode OS2, and choose a duplex cable when the link requires separate transmit and receive paths for switches, optical devices, or cross-connects.

Use pre-terminated patch cords for shorter connections between active equipment, passive optical devices, and cross-connects when you want to reduce field termination work. Choose bulk indoor fiber optic cable for backbone or interbuilding runs that require custom lengths, routing, or termination on-site.
