Duplex LC–LC Optical Patch Cable 9/125 µm Singlemode OS2, 7 m

Duplex LC–LC Optical Patch Cable 9/125 µm Singlemode OS2, 7 m is a factory-terminated fibre patch cord designed for duplex singlemode links. It features two LC connectors on each end and a 9/125 µm singlemode OS2 fibre construction for low attenuation and stable signal transmission over longer distances. The 7 m length makes it suitable for intra-rack, inter-rack and equipment-to-equipment connections in telecom rooms and data centers.

Advantages

The cable provides low insertion loss and high return loss consistent with OS2 singlemode performance. Duplex LC connectors offer compact form factor and secure latch for high-density installations. The standardized 9/125 µm core/cladding ratio ensures compatibility with common singlemode transceivers and patch panels. The 7 m length reduces the need for additional splices or extensions while keeping cable routing simple.

Suitable for

• Patch panels and fibre distribution frames in data centers
• Connections between switches, routers and optical transceivers
• Telecommunication room fibre trunking and intra-building backbone links
• Lab and test setups requiring duplex singlemode links

Key specifications

• Fibre type: Singlemode OS2
• Core/cladding diameter: 9/125 µm
• Connector type: Duplex LC to Duplex LC
• Polish type: Typically UPC or APC depending on variant (confirm before installation)
• Length: 7 meters
• Configuration: Duplex (two fibres)
• Typical insertion loss: Low (meets industry singlemode patch cord standards)

How to use

Route the patch cable avoiding tight bends and mechanical stress; maintain the minimum bend radius specified for singlemode fibre (check component documentation). Insert LC connectors into corresponding duplex LC ports until the latch clicks. When connecting to equipment, ensure transceiver and port types match the cable polish and fibre mode. Label or document both ends to simplify future maintenance and avoid accidental disconnection.

Usage recommendations

Store and handle the cable in a clean environment; avoid contaminating connector endfaces. Clean connectors with approved fibre cleaning tools before mating. For long-term installations, secure the cable to prevent strain on connectors and maintain required bend radii to preserve optical performance.
