Fiber Optical Duplex Cable InLine ST/ST 50/125µm OM3 15m

The InLine Fiber Optical Duplex Cable InLine ST/ST 50/125µm OM3 15m is a multimode duplex fiber patch cable designed for high-speed network links. With OM3 grade 50/125 µm glass fiber and ST connectors on both ends, the cable supports full-duplex data transmission over a 15 meter length. The construction is intended for use in structured cabling, server rooms, backbone runs, and equipment patching where low-loss, predictable multimode performance is required.

Advantages

This duplex fiber cable offers OM3 multimode performance optimized for 10 Gigabit Ethernet and parallel optics applications at moderate distances. The 50/125 µm core/cladding geometry provides consistent modal bandwidth and low attenuation. ST bayonet-style connectors ensure secure, repeatable mating in legacy and mixed-connector environments, while the duplex assembly maintains polarity for simultaneous transmit and receive channels. The 15 m length balances reach and manageability for rack-to-rack or rack-to-equipment connections.

Suitable for

• 10 Gigabit Ethernet links in data centers and LANs
• Multimode optical backbones and patch panels
• Connecting switches, servers, SAN equipment, and transceivers with ST interfaces
• Short to medium length fiber runs within telecom rooms or between cabinets

Key specifications

• Fiber type: Multimode OM3
• Core/cladding diameter: 50/125 µm
• Connector type: ST to ST duplex (bayonet)
• Length: 15 meters
• Polarity: Duplex (separate transmit and receive fibers)
• Typical applications: 10 GBASE-SR, multimode short-reach links
• Outer jacket: flexible cable jacket suitable for indoor use

How to use

Inspect connector endfaces for cleanliness before installation and clean with appropriate fiber cleaning tools if necessary. Verify the port type on your networking equipment is compatible with ST connectors or use adapters/converters where required. Connect each ST plug by aligning the bayonet and twisting to lock; maintain correct duplex orientation so the transmit fiber on one end connects to the receive fiber on the other end. Route the cable to avoid sharp bends that exceed the fiber's minimum bend radius and secure it with cable management hardware to prevent strain.

Usage recommendations

For optimal performance, use this OM3 duplex cable within its intended multimode reach limits (typical 10 Gigabit distances) and keep connector endfaces clean. Avoid tight bends and mechanical stress, and store the cable coiled without kinks when not in use. Where ST ports are not available, use suitable adapter modules or convert to the required connector type using a compatible patch panel.
