Fiber optic connector CBO SFA21BK13 LC male, BlueOptics SFA21BK13

BlueOptics SFA21BK13 LC male is an LC male fiber optic connector designed for single-fiber termination and high-density patching. The compact LC form factor provides a small footprint suitable for crowded patch panels, transceiver interfaces and professional cabling environments. This LC male variant is intended to deliver consistent optical alignment and reliable mechanical mating for single-mode fiber installations where space efficiency and repeatable performance are required.

Advantages

The LC male connector offers a compact design that reduces panel space and supports high-density layouts. It is engineered for repeatable insertion and removal with stable optical alignment, helping to maintain low insertion loss and consistent connection quality. The standardized LC interface ensures compatibility with widely used transceivers and housings, facilitating integration into existing fiber-optic infrastructures.

Suitable for

• High-density rack and patch panel installations
• Fiber-to-the-desk and structured cabling in data centers
• Connection to fiber transceivers and active networking equipment
• Single-mode fiber terminations and splicing interfaces

Key specifications

• Connector type: LC male (compact duplex-style footprint adapted for single-fiber use)
• Fiber compatibility: single-mode fiber applications
• Form factor: small-form-factor LC for high-density deployment
• Color: blue (industry color coding for single-mode/grade identification where applicable)
• Mechanical mating: designed for repeatable, secure insertion and retention

How to use

Prepare the fiber according to standard single-mode termination procedures, ensuring the fiber endface is properly cleaved and cleaned. Insert the fiber into the LC male connector following the manufacturer's termination method or the cabling kit instructions for this connector family. After termination, verify the physical connection by mating with a compatible LC female adapter or transceiver port and check optical performance with appropriate test equipment such as an optical power meter or OTDR to confirm acceptable insertion loss and continuity.

Recommendations

Handle the LC male connector with care to keep the ferrule and endface free of dust and contamination. Use dust caps when connectors are not mated and perform endface inspection and cleaning prior to connection. For best results in high-density environments, plan routing to minimize bend radius and mechanical stress on terminated fibers.
