There are several models and specifications of fiber optic welding trays

Fiber optic welding trays are designed to organize, protect, and manage spliced fibers, with capacities ranging from 12 to 48 fibers, varying dimensions, and compatibility with multiple closure and connector types.

Capacity and Fiber Management

Fiber optic splice trays are available in different capacities depending on the model:

• 12-fiber trays: Standard trays can hold up to 12 fibers, with each fiber protected by thermofits and organized in dedicated holders (length 180mm × width 100mm × height 10mm) suitable for closures like SC-209A and SC-302 .
• 16-fiber trays: Designed to accommodate up to 16 fibers, terminated with pigtails to 8× SC or 16× LC connectors, with built-in holders for 4 splices and additional PLC splitter capacity .
• 48-fiber trays: High-capacity trays allow welding and branching of up to 48 fibers, with stackable disks to expand capacity and facilitate installation in junction boxes .

Materials and Construction

• Plastic trays: Injection-molded trays provide lightweight, safe handling with no sharp edges, ensuring precise fiber winding and protection .
• Metal trays: Aluminum-based trays offer ruggedness, strain relief via crimpable tabs, and black powder coating for fiber identification and protection. They are suitable for both indoor and outdoor use and compatible with loose tube and tight-buffered cables .

Features

• Fiber protection: Splice points are protected using thermofits, heat-shrink tubes, or RTV sealing, depending on the tray type .
• Strain relief: Trays include multiple points for securing buffer tubes or pigtails using cable ties or crimpable tabs .
• Compatibility: Trays are designed to fit specific closures and boxes, such as SC-209A, SC-302, TB-002, or Corning interconnection hardware .
• Expandable design: Some trays allow stacking or modular expansion to increase fiber capacity without compromising organization .
• Connector support: Certain trays support SC, LC, or PLC splitter connections, enabling integration with various network configurations .

Dimensions

• Typical small trays: 180mm × 100mm × 10mm for 12-fiber models .
• Larger trays vary depending on fiber count and design, with stackable or modular options for higher capacities like 48 fibers .

Applications

Fiber optic welding trays are used in:

• Indoor and outdoor splice closures
• Junction boxes
• Network distribution panels
• Systems requiring organized, protected, and high-density fiber splicing These trays ensure efficient fiber management, protection against bending and stress, and compatibility with multiple splicing methods, making them essential components in fiber optic network installations .
