What is fiber optic fusion splicing in box 86

The 86-box fiber optic outlet is a compact, wall-mounted solution designed for indoor fiber termination, splicing, and storage, supporting high-performance fusion splicing in FTTH, FTTB, and broadband networks.

Overview

The 86-type fiber optic outlet is a standard 86×86 mm enclosure intended for indoor wall-mounted or flush-mounted installations in homes, apartments, and offices . It is widely used in FTTH (Fiber to the Home), FTTB (Fiber to the Building), PON (Passive Optical Networks), and broadband networks for end-user fiber connections and splicing . Its compact design allows seamless integration with standard electrical wall plates, providing a discreet and organized fiber termination point.

Features and Compatibility

  • Material Options: Standard ABS for cost-effective performance or V0 flame-retardant ABS (UL 94 V-0 rated) for enhanced fire safety indoors. For outdoor applications, a PC/ABS blend ensures UV resistance, impact strength, and weatherproofing .
  • Fiber Management: The box supports termination, splicing, and storage of fiber optic cables, accommodating two SC adapters for flexible connectivity. It is compatible with G.657A1 and G.657B3 bend-insensitive fibers, ensuring minimal signal loss even in tight bends .
  • Splicing Integration: Designed to facilitate fusion splicing, the 86-box allows secure fiber routing while protecting the bend radius, maintaining signal integrity, and reducing insertion loss compared to mechanical splicing .
  • Compact Structure: Optimized for limited space, the internal layout ensures organized fiber management and easy access for splicing operations .

Installation and Use

  1. Mounting: Can be installed flush or surface-mounted on walls, aligning with standard electrical boxes.
  2. Fiber Preparation: Fibers should be stripped, cleaved, and cleaned according to standard fusion splicing procedures to ensure low-loss connections .
  3. Splicing: Using a fusion splicer, fibers are permanently joined inside the box. The enclosure protects the splice from environmental factors and mechanical stress .
  4. Adapter Connection: SC adapters allow easy connection to end-user devices or patch panels, supporting flexible network configurations .

Advantages

  • Low Insertion Loss: Fusion splicing within the 86-box provides a permanent, low-loss connection.
  • Space Efficiency: Compact design fits standard wall plates without compromising fiber management.
  • Durability: Flame-retardant and UV-resistant materials enhance safety and longevity.
  • Versatility: Suitable for both single-mode and bend-insensitive fibers, supporting modern high-speed networks. The 86-box fiber optic outlet is an ideal solution for efficient, reliable, and organized fiber splicing and termination, making it a key component in modern indoor fiber optic deployments .
