Which type of melt fiber tray is recommended

For fusion splicing applications, a standard or mass fusion splice tray with heat-shrink splice protectors is recommended, ensuring proper fiber protection and organization.

Key Considerations for Melt Fiber Trays

1. Tray Type:

• Standard Splice Trays: Suitable for general applications, accommodating a moderate number of splices. They are flexible and can be used in various network setups .
• Mass Fusion Splice Trays: Ideal for high-density installations where multiple fibers are spliced simultaneously, such as ribbon cables. These trays maintain the minimum fiber bending radius and reduce handling complexity .
• Single Fiber or Ribbon Trays: Single fiber trays are used for careful management of individual fibers, while ribbon trays are designed for multiple fibers joined in ribbons, simplifying high-density splicing . 2. Splice Protection:
• Use heat-shrink (3A) splice protectors to secure fusion splices. These protectors provide mechanical strength and prevent fiber damage during handling .
• Trays should accommodate double-stacked heat-shrink protectors up to 60mm long for optimal protection . 3. Material and Design:
• Trays are typically made from ABS plastic with rounded edges and radius tabs to prevent microbends or fiber snagging .
• Integrated routing features help organize fibers and maintain proper bend radius, which is critical for minimizing signal loss . 4. Capacity and Compatibility:
• Choose a tray based on the number of fibers and type of splices. For example, C and D size trays can handle up to 36 single fiber splices or 216 mass fusion fibers for C trays, and up to 96 single fiber splices or 288 mass fusion fibers for D trays .
• Ensure the tray is compatible with the closure or enclosure system being used. 5. Installation Tips:
• Position the tray close to splicing equipment to reduce the risk of fiber breakage .
• Bundle pigtails with vinyl tape and secure with cable ties to maintain organization and prevent stress on the fibers .

Recommendation

For most fusion splicing applications, a mass fusion splice tray with heat-shrink splice protectors is recommended. This type of tray provides:

• High-density fiber management
• Protection against mechanical strain
• Compatibility with ribbon and single fibers
• Ease of installation and maintenance For smaller installations or single fiber splicing, a standard or single fiber tray may be sufficient, but always ensure the tray supports heat-shrink splice protectors and maintains proper fiber bend radius.
