Fiber Optic Splice Kit
Fiber Optic Splice Kit for Specialty Applications
The fiber optic splice kit enclosure family of products are designed to fill a specialized application need. They were originally created to help close the digital divide that rural communities face by splicing together miles of high-speed fiber-based broadband cables underwater.
Product Description
All fiber optic splice kits are designed for ease of installation anywhere along the cable to create a highly reliable, full ocean depth splice with multiple levels of sealing protection.
The splice kit contains:
- Room-temperature cure polyurethane
- Splice tray
- Precision precast compression dams
- EVERFLEXTM Bending Strain Relief or Armor Rods
- Split marine-grade, stainless steel enclosure (Titanium, stainless steel, and Delrin® enclosures available upon request)

Applications
Standard and customizable fiber optic splice for a variety of applications in any body of water (ocean, rivers, lakes, etc.)
Features and Benefits
- Standard and customizable fiber optic splice for a variety of applications.
- Paired with EVERFLEXTM Bending Strain Relief or Armor Rods for the perfect, optical/mechanical termination and to provide tailored bending and strain relief protection.
- Compression dams prevent leak water penetration along non-bondable surfaces.
- Fiber optics are spliced and set in 12-, 24-, or 48-capacity trays. (Other variations available upon request.).
- Polyurethane fill encapsulates the entire interior of the enclosure.
- Isostatic nature of the seal (same pressure exists on all sides of the seal) prevents water migration.
- Note: Special designs including cables with conductors are also available upon request.
