Fiber Optical Duplex Cable LC/LC 9/125µm OS2 3m InLine 88656J

The InLine Fiber Optical Duplex Cable LC/LC 9/125µm OS2 3m provides a single-mode duplex link for high-speed, low-loss optical connections. Designed for long-distance data transmission, the cable uses a 9/125 µm core/cladding profile and OS2-grade single-mode fiber. Both ends are terminated with LC connectors in a duplex housing, ensuring compact, reliable mating with network devices that accept LC interfaces. The 3 metre length suits patching between racks, connecting optical transceivers, or linking distribution panels in structured cabling environments.

Advantages

This fiber optical duplex cable delivers low insertion loss and high return loss typical of OS2 single-mode fibers, supporting consistent signal quality over extended distances. The LC/LC termination offers space-saving duplex connections and secure mechanical latching for stable links. The cable assembly is built to industry standards for fiber geometry and connector polish, providing predictable optical performance and compatibility with common networking equipment. Its 3 m length balances reach and cable management in server rooms and telecom closets.

Suitable for

• Interconnecting optical transceivers (SFP/SFP+, XFP) and switches with LC ports
• Patching between rack-mounted panels or fiber distribution frames
• Structured cabling links in data centres and telecommunications rooms
• Fiber link testing and temporary connections during deployment

Key specifications

• Fiber type: single-mode OS2
• Core/cladding diameter: 9/125 µm
• Connector type: LC duplex to LC duplex
• Polish/finish: connector polish appropriate for single-mode (PC/APC as applicable)
• Cable length: 3 m
• Application: indoor patch cable for high-speed optical networks

How to use

Route the cable to avoid sharp bends and secure it using existing cable management to maintain the minimum bend radius recommended for single-mode fiber. Align the LC duplex plug with the LC socket and insert until the latch engages; to remove, depress the latch and pull the connector straight out. Verify proper connection by checking link status on connected equipment and, if required, measure insertion loss and return loss with suitable optical test instruments. Store unused cable neatly coiled to prevent kinks and contamination of connector endfaces.

Usage recommendations

Before installation, inspect connector endfaces with a fiber inspection scope and clean with approved fiber cleaning tools if contamination is present. Maintain bend radii and protect connectors with dust caps until mating. For critical links, test and document optical performance after installation to ensure compliance with system requirements.
