Fibre Optic Adapter ST MetzConnect 150900D1-I Steel

The MetzConnect 150900D1-I Steel fibre optic adapter with ST connector type provides a compact, metal-bodied coupling for single-mode optical links. Designed with uncoated contacts and a robust steel housing, this adapter supports physical ST-style plug-and-socket connections and is intended for applications that require durable, repeatable mating of ST connectors. The product is sold as a single unit and complies with applicable RoHS restrictions.

Advantages

The steel construction offers mechanical strength and improved resistance to deformation compared with plastic housings, while the ST connector interface ensures straightforward push-and-turn mating compatible with legacy and current ST-equipped equipment. Uncoated contacts reduce concerns about coating compatibility and can be used where ceramic or metal ferrule interfaces are required. Compliance with RoHS confirms restricted use of hazardous substances in the adapter's materials.

Suitable for

• Single-mode fibre connections using ST connectors
• Patch panels, wall plates, and bulkhead installations requiring a durable metal adapter
• Laboratory and field testing setups where repeatable ST mating cycles are needed
• Environments where RoHS-compliant components are required

When it may not be suitable

This adapter is intended for ST connector interfaces only and is not compatible with other connector types such as LC, SC, or FC without additional conversion hardware. It is specified with uncoated contacts; applications that require specific coated ferrules or specialized low-reflectance treatments should verify compatibility before use. For multimode networks, confirm that single-mode design fits the system requirements.

Key specifications

• Connector type: ST-style coupling
• Housing material: steel
• Contact finish: uncoated ferrule interface
• Application: single-mode fibre optical connections
• Compliance: RoHS-restricted substances compliant

How to use

Mount the adapter into the panel, wall plate, or bulkhead aperture designed for ST couplings, ensuring secure mechanical fixation. Insert the ST connector plug into the adapter and engage the bayonet-style push-and-turn motion until seated. For removal, depress and rotate as required by the ST mechanism and withdraw the connector. Maintain clean ferrule endfaces using appropriate fibre cleaning tools before mating to minimise insertion loss and back-reflection.

What to consider before purchase

• Confirm the system uses ST connectors and that single-mode optical performance is suitable.
• Verify required housing material—steel for increased durability versus plastic alternatives.
• Check whether uncoated contact ferrules meet your connector finish requirements.
• Ensure required panel or bulkhead cutouts match the adapter's mechanical profile.

Usage recommendations

Regularly clean fibre endfaces and inspect the adapter for mechanical damage. Use appropriate strain relief and cable management to prevent undue stress on connectors and the steel housing. Store unused adapters in protective packaging to avoid contamination.
