The IU-CEN-ODF-12-TRAY-V3 is a 12-core fiber optic splice tray designed for efficient fiber management, storage, and fusion protection, making it an ideal choice for various installations. This tray ensures organized, secure, and easy-to-operate management of fiber optic cables. It provides a secure location for fiber splicing, allowing for easy installation and movement while expanding splice capabilities. The tray features a widely used welding plate that supports light welding, adapter pigtail installation, and a small number of asylums, commonly found in high-density wiring boxes and outdoor optical cable transfer boxes. Each of the 12-core units accommodates pigtails, cables, and beam tubes, providing effective hierarchical management while offering excellent protection from damage. The tray is designed with a three-tier structure that includes a bottom plate for wiring, a middle plate for welding, and a top cover for integration, making the operation process seamless and efficient. It ensures that the bend radius of optical fibers at any position is always greater than 40mm, which is critical for maintaining fiber integrity. The adapters are positioned at a 30-degree angle, ensuring the proper bend radius and preventing laser eye injuries. The tray also simplifies the welding and wiring process by providing clear instructions and records. It is compatible with SC, FC, LC, and ST adapters, and supports both ribbon and bunchy optical fibers. The tray is designed for installation in ODF and terminal boxes, offering flexibility in various application scenarios. With installation dimensions of 304mm x 182mm x 25mm, the tray features a disk mode design to ensure proper fiber bending radius and redundancy. Made from durable ABS material, it guarantees long-lasting performance and protection for fiber optic cables.
