Fiber optic splice closure Doerr PUH-FC-CASE — compact protective case for fiber splices

PUH-FC-CASE is a compact fiber optic splice closure from Doerr designed to protect and organize fiber splices in telecom and data networks. The case provides a sealed environment for either fusion or mechanical splices and accepts splice trays and cable entries while enabling neat routing and secure retention of fibres. It is intended for indoor use or in protected outdoor locations where a small, robust protective enclosure is required.

Advantages

The closure combines a compact footprint with straightforward internal organization to simplify splice management and reduce space requirements in cabinets, enclosures, or sheltered junction points. Its sealed construction protects splices from dust and moisture while allowing access for installation and maintenance. The design supports both fusion and mechanical splices and accommodates multiple cable entries for flexible network configurations.

Suitable for

• Indoor splice points in telecom closets and data cabinets
• Protected outdoor enclosures and sheltered street cabinets
• Small distribution nodes, branch connections, and premises wiring
• Temporary or permanent installations where space is limited

Key specifications

• Compact protective enclosure for fiber splices
• Supports fusion and mechanical splice types
• Holds splice trays and secures fiber routing
• Sealed against dust and moisture for protected environments
• Multiple cable entry points for flexible cabling layouts

How to use

Open the closure and place the required number of splice trays inside, positioning incoming and outgoing cables through the designated entry points. Perform fusion or mechanical splicing according to standard optical fibre procedures, secure the splices in the trays and route excess fibre into the storage area to avoid sharp bends. Close and seal the case to restore environmental protection. Ensure cable retention features are engaged to prevent strain on the splices.

Usage recommendations

For reliable performance, install the closure in a dry, sheltered location and follow fibre handling best practices: use proper cleaning, correct splice protectors, and maintain minimum bend radii for the fibres. Verify sealing after installation and recheck access points during routine maintenance.
