Indoor/Outdoor OM1 62.5/125 Multimode Fiber Optic Cable by the Foot

The Indoor/Outdoor OM1 62.5/125 Multimode Fiber Optic Cable offers a durable, versatile solution for short-distance, high-reliability fiber deployments. This plenum-rated, tight-buffered distribution cable is built with Corning® optical glass, a UV-resistant outer jacket, and water-blocking aramid yarn strength members. It’s suitable for both indoor and outdoor applications, making it ideal for installations that transition between building interiors and underground conduit or other exterior locations.

Because this cable is plenum rated, it can be safely installed in areas that require low-smoke, flame-retardant construction, including air-handling spaces and interior ventilation paths, eliminating the need to transition to different cables at the building entry point.

Built for Your Application

This fiber optic cable line simplifies your planning and installation process. Whether you’re linking multiple buildings through underground conduit, terminating at a fiber rack system, or building an intra-building backbone, these cables are ready to meet your needs. The dual-rated indoor/outdoor jacket provides flexibility and peace of mind for installations that span environmental zones, while the fiber-by-the-foot format gives you exactly the length you need—no more, no less.

For projects where exposure to blunt force or rodent activity is not a concern, this cable can even be left exposed in outdoor environments. With its plenum rating, it also meets stringent NFPA safety standards for indoor spaces.

FAQ

Can this cable be used both indoors and outdoors?

Yes. The cable is rated for both indoor and outdoor use, including direct exposure to the elements where rodent or blunt force damage is not a concern. The UV-resistant jacket and water-blocking aramid yarn make it suitable for underground or exposed outdoor environments.

Is this cable fire-rated for plenum spaces?

Yes. It includes a plenum-rated jacket, meaning it meets NFPA low-smoke and fire safety standards for air-handling and ventilation spaces inside buildings.

Does this cable come with connectors?

No, this product line is for bulk fiber only and does not come with connectors. If you need terminated cables, we offer pre-terminated assemblies on our site that are available with a variety of connector options.

Can I choose a specific length?

Absolutely. These cables are sold by the foot, so you can order the exact length you need—anywhere from 10 feet to 5000 feet. This helps reduce waste and cost.

Can I add pulling eyes to make installation easier?

Yes, you can choose to have pulling eyes factory-installed, which helps protect the cable during pulls through conduit or riser pathways.
