InLine Fiber Optical Adapter Metal Duplex ST/ST MM Ceramic Sleeve with Flange

InLine Fiber Optical Adapter Metal Duplex ST/ST MM Ceramic Sleeve with Flange is a metal duplex adapter designed for ST-to-ST multimode fiber connections. The adapter uses a ceramic alignment sleeve to improve durability and optical performance and comes with a flange for straightforward panel or chassis installation. Its silver finish suits professional networking environments and helps provide stable, low-loss connections in multimode applications.

Advantages

The metal duplex construction ensures mechanical strength and grounding where required, while the ceramic sleeve maintains precise fiber alignment for consistent signal transmission. The included flange simplifies mounting in racks, panels or enclosures, and the ST/ST interface provides wide compatibility with standard multimode transceivers and patch cords.

Suitable for

• Multimode fiber optic patch panels and distribution frames
• Chassis or wall-mount enclosures requiring ST connections
• Network installations needing durable, panel-mounted duplex adapters

How to use

Mount the adapter to a compatible panel or chassis using the flange and appropriate screws. Insert ST multimode patch cords into each ST port until the bayonet latches engage. Ensure fiber ends are clean and inspected before mating to minimize insertion loss. For removal, depress the bayonet latch and withdraw the connector straight out.

Recommendations

Use with clean, inspected multimode ST patch cords and follow standard fiber handling procedures. Avoid excessive bending of connected fibers and secure cables to prevent strain on the adapter. For best performance, periodically clean the ceramic sleeve and connector endfaces with recommended fiber cleaning tools.
