ACT LC-LC quad fibre optic adapter singlemode OS2

The ACT Fiber optic LC-LC quad adapter EA1020 is designed for single-mode OS2 fiber networks and provides a compact interface with LC duplex-style ports arranged in a quad configuration. The adapter uses LC connectors with blue color coding to indicate single-mode operation and supports fiber-to-fiber mating with low insertion loss and consistent optical performance. Its compact footprint makes it suitable for high-density patch panels and fiber distribution frames where stable, low-loss connections are required.

Advantages

The adapter offers precise alignment and polished ferrule contact to minimize return loss and insertion loss in single-mode links. Its quad LC layout increases port density while maintaining accessibility, and the blue color coding simplifies identification during installation and maintenance. The durable housing protects fiber endfaces and ensures reliable mating cycles for routine network operations.

Suitable for

• Single-mode OS2 backbone and campus fiber links
• High-density data center patch panels and fiber enclosures
• Telecommunications distribution frames and network racks
• Fiber testing and temporary fiber-to-fiber connections

Key specifications

• Connector type: LC to LC, quad configuration
• Mode: Single-mode (OS2)
• Color coding: Blue (single-mode identification)
• Typical insertion loss: low (manufacturer-grade polished ferrules)
• Return loss: high performance suitable for single-mode applications
• Housing: compact, suitable for high-density mounting
• Durability: designed for multiple mating cycles

How to use

Install the LC-LC quad adapter into the compatible panel or enclosure by aligning it with the mounting slot and securing it according to the panel design. Clean connector endfaces before mating using appropriate fiber cleaning tools to avoid contamination-related loss. Insert LC patch cords into each LC port until they click into place, ensuring correct polarity for transmit/receive pairs. For removal, depress the LC latch and gently withdraw the connector to avoid stress on the ferrule and fiber.

Recommendations

Regularly inspect and clean connector endfaces before each mating, use dust caps when ports are unused, and follow standard single-mode handling practices to maintain low insertion loss and reliable long-term performance.
