Optical Fiber Cables

From single‑mode to multimode, indoor to outdoor – we provide every fiber type for your high‑speed, long‑distance connectivity needs.

SMF (Single‑Mode Fiber)

Single‑Mode Fiber features a small core (≈9 µm) that allows only one mode of light to propagate. It offers extremely low attenuation and high bandwidth over long distances, making it ideal for telecommunications, CATV, and long‑haul networks.

MMF (Multimode Fiber)

Multimode Fiber has a larger core (50 µm or 62.5 µm) that supports multiple light modes simultaneously. It is cost‑effective for shorter distances (up to 2 km) and commonly used in data centers, LANs, and premises cabling.

OM1, OM2, OM3, OM4, OM5

OM1 (62.5 µm): 200/500 MHz·km, supports up to 1 Gb over 275 m.
OM2 (50 µm): 500 MHz·km, supports 1 Gb up to 550 m.
OM3 (50 µm, laser‑optimized): 2000 MHz·km, supports 10 Gb up to 300 m.
OM4 (50 µm, enhanced): 4700 MHz·km, supports 10 Gb up to 550 m / 100 Gb up to 150 m.
OM5 (wideband): Supports short wavelength division multiplexing (SWDM) for 40/100 Gb over a single fiber pair.

Armored & Unarmored Fiber

Armored Fiber: Includes a metal or interlocking armor layer between the jacket and the strength members. It provides extra protection against rodents, crushing, and moisture – ideal for direct burial or harsh environments.

Unarmored Fiber: Lighter and more flexible, suitable for indoor conduit runs or protected pathways where mechanical protection is not critical.

Indoor & Outdoor Fiber

Indoor Fiber: Designed with flame‑retardant jackets (OFNR, OFNP) for use inside buildings. Often tight‑buffered for easy termination.

Outdoor Fiber: Built to withstand UV radiation, moisture, and temperature extremes. Typically loose‑tube construction with water‑blocking gels or tapes. Can be installed aerially, in ducts, or directly buried.

Fiber Construction Types

Loose Tube: Fibers are loosely placed in gel‑filled tubes, protecting them from moisture and stress. Ideal for outdoor and long‑distance applications.
Tight Buffered: Each fiber has a direct polymer coating, making it robust and easy to connectorize – perfect for indoor and patch cords.
Ribbon: Fibers are arranged in parallel ribbons, allowing high‑density splicing and mass fusion splicing.
Breakout: Multiple tight‑buffered fibers are bundled under a common jacket, each with its own strength members – very rugged and suitable for direct termination.
Distribution: Tight‑buffered fibers bundled together without individual strength members – compact and ideal for backbone cabling inside buildings.

Frequently Asked Questions

What is the main difference between SMF and MMF?

Single‑mode fiber has a smaller core and supports only one light path, enabling longer distances and higher bandwidth. Multimode fiber has a larger core, supporting multiple light paths, but is limited to shorter distances (up to a few kilometers).

When should I use OM5 fiber?

OM5 (wideband) is designed for short wavelength division multiplexing (SWDM), allowing 40/100 Gbps transmission over a single pair of fibers using multiple wavelengths. It’s ideal for data centers that need to scale without adding more fibers.

Can armored fiber be used indoors?

Yes, armored fiber can be used indoors, but its rigidity may make installation more difficult. It is often chosen for indoor runs that require extra protection against rodents or physical damage.

What does 'loose tube' construction protect against?

Loose tube fibers are isolated from external stress and moisture by gel‑filled tubes. This design allows the fibers to expand or contract with temperature changes and protects them from water ingress, making it ideal for outdoor and direct burial applications.
