InLine Fiber Optical Duplex Cable LC/LC 9/125µm OS2 20m

The InLine Fiber Optical Duplex Cable LC/LC 9/125µm OS2 20m is a single-mode duplex fiber cable designed for long-distance data transmission. It has a 9 µm core diameter and OS2-grade fiber construction to support low attenuation and stable signal integrity over extended runs. Both ends are terminated with LC connectors for compact, standardized connections in networking and telecommunications equipment.

Advantages

This fiber optical duplex cable offers low insertion loss and high return loss consistent with OS2 single-mode performance, making it suitable for backbone links and inter-building connections. The LC/LC termination provides a small form factor that fits dense patch panels and transceiver ports. The 20 m length provides flexibility for racks, cabinets and intermediate routing without excess slack, while the cable design minimizes bending loss and maintains consistent transmission characteristics.

Suitable for

• Backbone and campus fiber links
• Data center patching and interconnects
• Telecommunications equipment connections
• Fiber-to-the-building (FTTB) and long-distance LAN runs

Key specifications

• Fiber type: single-mode, OS2
• Core/cladding diameter: 9/125 µm
• Connector type: LC to LC, duplex
• Length: 20 m
• Polish and performance: typical single-mode low-loss characteristics suitable for long-distance transmission
• Compliance: standard fiber optic connector form factor and assembly suitable for networking equipment

How to use

Route the cable between devices or patch panels avoiding tight bends and kinks; maintain a bend radius consistent with single-mode fiber specifications to prevent increased attenuation. Insert LC connectors into compatible LC ports until the latch engages, ensuring clean ferrule endfaces before connection. When disconnecting, press the latch and pull straight out to avoid stress on the cable. For installations in racks or conduits, secure the cable with appropriate clips or ties to prevent strain at connector ends.

Recommendations

Inspect and, if necessary, clean connector endfaces with an optical-grade wipe or fiber cleaning tool before each connection. Store spare cable coils loosely to avoid permanent bends and keep the cable away from sources of excessive heat or mechanical abrasion. For critical links, verify optical loss and continuity with an appropriate test instrument after installation.
