Fibre Optic Adapter LC/LC Tecline 90780 Blue

The Tecline 90780 fibre optic adapter LC/LC in blue is designed for single-mode fibre connections and provides a compact coupling solution for LC-terminated cables. It connects two LC-style plugs with physical alignment to maintain signal integrity and low insertion loss, suitable for patch panels, wall outlets and inline splices where single-mode transmission is required. The blue housing offers quick visual identification for single-mode links according to common colour conventions.

Advantages

This LC/LC fibre optic adapter delivers precise ferrule alignment for consistent low insertion loss and return loss in single-mode networks. Its compact footprint enables high-density installations in racks and patch panels while the sturdy blue housing resists mechanical stress and repeated mating cycles. The adapter is compatible with standard LC connectors and is intended to support stable, low-latency data transmission in telecommunications and data centre environments.

Suitable for

• Single-mode fibre patch panels and shelf installations
• Connecting LC-terminated pigtails and jumpers in fibre distribution frames
• Wall outlets and communication cabinets where space-saving LC duplex connections are required
• Testing and temporary links during fibre maintenance or commissioning

Key specifications

• Connector type: LC to LC duplex coupling
• Fibre type: single-mode compatibility
• Housing colour: blue for single-mode identification
• Form factor: compact duplex adapter for high-density panels
• Typical performance: engineered for low insertion loss and reliable return loss (values depend on connector polish and mating)

How to use

Install the adapter into the panel or bracket designed for LC duplex couplers, ensuring the mounting aperture and retention clips match the adapter's form factor. Insert LC connector plugs into each side until a positive click is felt; inspect connectors and clean ferrule end-faces before mating to minimise insertion loss and prevent contamination. For temporary connections, fully seat both LC plugs and avoid lateral stress on the cable. When removing, depress the LC latch and pull straight out to prevent damage to the ferrule or housing.

Usage recommendations

Use fibre cleaning tools and inspection microscopes to verify end-face quality before connection, and follow standard single-mode handling practices: avoid tight bends, protect connectors with dust caps when not in use, and limit mating cycles to the manufacturer's recommended number to preserve performance.
