Pigtail type round to round type

Pigtail type cables have a connector on one end and a bare fiber or wire on the other for splicing, while round-to-round type (circular) connectors have connectors on both ends for direct plug-and-play connections.

Pigtail Type

A pigtail is a short cable segment with a factory-terminated connector on one end and a bare fiber or wire on the other. In fiber optics, the bare end is designed for fusion or mechanical splicing to an incoming cable, while the connector end plugs into equipment, patch panels, or splice trays. This design ensures low-loss, permanent connections and is commonly used in structured cabling, data centers, and FTTH (fiber-to-the-home) installations.

Pigtails are ideal when you need custom-length splicing and precise factory-quality connectors.

Round-to-

Round Type (Circular Connectors)Round-to-round connectors, also called circular connectors, have connectors on both ends and are designed for direct connection between devices or cables. They are widely used in industrial, medical, automotive, and military applications due to their durability, vibration resistance, and secure locking mechanisms. Circular connectors can transmit power, signal, or data, and are available in multiple sizes, pin configurations, and sealing options for harsh environments.

They are plug-and-play, making them suitable for quick installation and maintenance.

Round-to-round (circular) connectors are used for robust, direct connections in industrial or electrical applications where plug-and-play convenience and environmental protection are important. Choosing between them depends on whether the installation requires splicing flexibility or immediate connectivity.
