STFiber Optic Adapter — Bayonet Mount, Metal & Plastic
ST fiber optic adapter with bayonet-style coupling for connecting two ST-terminated fibers. Available in metal and plastic body options. Zirconia ceramic sleeve for precise 2.5mm ferrule alignment. Widely used in legacy Ethernet, industrial control, and military fiber networks.
Technical Specifications
Engineered For Performance
Bayonet Twist-Lock Coupling
Quarter-turn bayonet mechanism provides secure, vibration-resistant connections with quick connect/disconnect — faster than threaded FC while more secure than push-pull designs.
Dual Sleeve Options
Zirconia ceramic sleeve for single mode applications requiring maximum precision, and phosphor bronze sleeve for cost-effective multimode installations.
Metal and Plastic Housing
Metal housing for industrial and military applications requiring durability and EMI shielding; plastic housing for cost-sensitive enterprise and campus network deployments.
Legacy Network Compatibility
Maintains interoperability with existing ST-based 10BASE-FL, 100BASE-FX Ethernet, and FDDI networks, supporting brownfield upgrades without full re-termination.
Typical Applications
Legacy Ethernet Networks
ST adapters in 10BASE-FL and 100BASE-FX multimode fiber Ethernet switches, media converters, and patch panels in campus and building backbone networks.
Industrial Control Systems
Bayonet-lock ST connections in factory automation, SCADA, and process control networks where vibration resistance and rugged construction are essential.
Military & Defense
ST adapters in military communication systems, shipboard networks, and field-deployable fiber equipment where reliable, quick-connect fiber coupling is required.
