Fiber Optic Splice Enclosures

Fiber Optic Splice Enclosures and Splice Case

INTRODUCTION

A Fiber Optic Splice Enclosure—often called a FOSC or Fiber Joint Closure—is designed to join and protect fiber cables from underground moisture, extreme temperatures, and other environmental factors. These robust enclosures are critical in CATV, telecommunications, and fiber-optic networks, offering watertight protection and flexible cable routing for aerial, duct, or direct-buried setups.

TYPES

1. Dome Fiber Splice Case
   • Cable inputs at both ends.
   • Includes advanced sealing, commonly known as a “3-in 3-out dome enclosure for FTTH applications.”
2. Inline (Horizontal) Opticube Enclosures
   • Cable inlets at the bottom.
   • Suitable for splicing or branching multiple optical cables in harsh environments.
3. IP68 Outdoor Splice Enclosure
   • Rated for challenging conditions, making it a “high-capacity fiber splice closure for underground cable networks.”
   • Perfect for -40°C to +65°C environments (or -40°F to +149°F).

KEY FEATURES

• Waterproof Fiber Optic Closure design with reliable sealing technology, often tested to IP68 standards.
• Protective splice cassettes inside each Cable Joint Box, ensuring safe and organized splicing.
• Able to accommodate multiple cable ports, large splice capacities (e.g., 96 to 192 cores), and even house a fiber splitter to distribute optical signals.
• Engineered from high-grade plastics for durability, lightweight handling, and lower maintenance costs.

APPLICATIONS

• Essential for aerial, underground, and duct-mounted installations where cables require secure branching or splicing.
• Ideal for telecom, FTTH, FTTB, and broadband expansions, ensuring long-term reliability.
• Some models integrate a splitter to facilitate multi-endpoint connectivity in CATV or fiber-optic networks.
• Perfect for “critical network infrastructure” where downtime prevention and speedy repairs are paramount.
