A splice board (more commonly called a splice tray) is a small, flat component used to organize and protect fiber optic cable connections inside an enclosure.

Definition, Capacity & Selection Guide ■ What Is a Fiber Optic Splice Tray? With the growth of FTTH, FTTx, and telecom fiber networks, the. Splice trays are internal fiber management structures used to organize, protect, and separate optical fiber splices inside closures, terminal boxes, and distribution enclosures. Their primary function is mechanical rather than optical. It holds individual fibers in place after they've been joined together, keeping the delicate splice points secure and preventing signal loss. Optical fiber termination by fusion splicing or mechanical splicing is very common now with the increasing development of fiber optic network. As optical fibers are sensitive to pulling, bending and crushing forces, fiber splice tray is used to provide a safe routing and easy-to-manage environment.
