Fibre Optic Adapter ST/ST Tecline 90701

The Tecline 90701 Fibre Optic Adapter ST/ST is a precision connector designed for reliable multi-mode fiber connections. Its metallic finish provides mechanical strength and stable alignment between ST male connectors, ensuring consistent optical signal transmission in networking and telecommunications setups. The adapter supports quick coupling and uncoupling of fiber patch cords while maintaining low insertion loss typical for well-made ST/ST mating sleeves.

Advantages

The metal body increases durability and resistance to mechanical wear compared with plastic housings, while the standard ST interface ensures broad compatibility with equipment that uses bayonet-style ST connectors. Construction with precision-aligned ferrules helps minimize insertion loss and back-reflection, supporting stable data transmission in local networks and short-range multimode links.

Suitable for

• Connecting multi-mode fiber patch cords in LAN and data center environments
• Telecommunications equipment and terminal boxes with ST connectors
• Field installations and repairs where quick connector mating is needed
• Test setups and temporary fiber links for diagnostics

Key specifications

• Connector type: ST to ST mating adapter for multi-mode fiber
• Housing material: metallic finish for enhanced durability
• Fiber mode: multimode compatibility
• Coupling mechanism: bayonet-style ST coupling
• Application: indoor networking, telecommunications, patch panels

How to use

Align the bayonet key of the ST connector with the adapter sleeve and insert the connector until it seats; rotate the connector slightly if needed to engage the bayonet locking mechanism. Repeat the process for the opposing connector end. Verify secure mechanical coupling and inspect fiber endfaces for cleanliness before connecting to minimize insertion loss. Use appropriate dust caps when the adapter is not in use to protect ferrules from contamination.

Usage recommendations

Prior to connection, clean fiber endfaces with approved fiber cleaning tools and visually inspect for scratches or contamination. Avoid excessive bending of fiber cables near the adapter and secure cables to prevent stress on the connection. For environments with high vibration or outdoor exposure, consider additional protective enclosures; this adapter is intended primarily for indoor and controlled environments.
