Fibre optic duplex cable LC/SC 9/125µm OS2 2m InLine 88656D

The InLine Fiber Optical Duplex Cable LC/SC 9/125µm OS2 2m is a single-mode duplex fiber patch cable engineered for reliable high-speed data transmission. With a 9 µm core and OS2-grade fiber, the cable supports long-distance links with low attenuation and is terminated with LC connector on one end and SC connector on the other, enabling flexible connectivity between transceivers, switches, media converters and patch panels. The 2 m length suits rack-to-rack, equipment-to-equipment and desktop connections where full duplex communication is required.

Advantages

This duplex cable offers low insertion loss and controlled return loss consistent with OS2 single-mode specifications, helping to preserve signal integrity across extended runs. The LC and SC connectors provide secure mating and dense port compatibility: LC for compact transceiver ports and SC for common patch panel interfaces. The 9/125 µm core/cladding geometry is standard for single-mode networks and minimizes modal dispersion, while the simple 2 m form factor reduces excess slack in short links.

Suitable for (tasks / use cases)

• Connecting single-mode transceivers in data center and telecom equipment
• Linking switches, routers and media converters over short to medium distances
• Patch panel to network device connections in server rooms and wiring closets
• Laboratory and testbed setups requiring LC-to-SC duplex connections

Key specifications

• Fiber type: single-mode (OS2)
• Core/cladding diameter: 9/125 µm
• Connector A: LC duplex
• Connector B: SC duplex
• Length: 2 m
• Polarity: duplex (full duplex support)
• Typical attenuation: compatible with OS2 single-mode performance (low loss)

How to use

Inspect connector endfaces for contamination before installation and clean if necessary with appropriate fiber cleaning tools. Align and insert the LC connector into the LC transceiver or adapter and the SC connector into the corresponding SC adapter or port until both connectors click securely. Route the cable to avoid sharp bends—maintain bend radii recommended for single-mode fiber—and secure with cable management accessories to prevent strain on connector terminations. Verify link operation using network diagnostics or optical power testing to confirm expected performance.

Recommendations

Store the cable coiled without tight loops and keep connector dust caps in place when not connected. For best results in critical links, perform insertion loss and return loss measurements after installation and follow standard single-mode fiber handling procedures to maintain long-term reliability.
