What is the fiber optic splice tray called

A fiber optic splice tray is also commonly called a splice board or splice cassette.

A fiber optic splice tray is a component used to organize, protect, and manage fiber optic splices inside enclosures, cabinets, or distribution frames, ensuring that delicate fiber connections are secure and properly routed . In telecommunications and networking, it is often referred to as a splice board, which emphasizes its role as a flat platform for holding individual fiber splices in place . Another term used is splice cassette, particularly in high-density or modular systems where trays can be inserted or removed from enclosures for easier maintenance . These trays are designed to maintain the minimum bend radius of fibers, prevent mechanical stress, and provide organized routing channels for both fusion and mechanical splices . They are typically compact, lightweight, and configured to hold 12, 24, or more fiber splices, depending on network requirements . Fiber splice trays are often installed inside fiber optic splice closures, distribution boxes, or patch panels, and may include features like hinged or stackable designs for easier access and higher density management . In summary, the terms splice tray, splice board, and splice cassette are used interchangeably in fiber optic networking to describe the same essential component that organizes and protects fiber splices while maintaining network reliability and performance .
