Fiber Fusion Splicing Services

What Is Fiber Fusion Splicing?

 

Fiber fusion splicing is a process that permanently joins two fiber optic strands by precisely aligning and fusing them together using controlled heat. This method creates a continuous optical path with minimal signal loss and reflectance.

​

Fusion splicing is the preferred splicing method for single-mode and multimode fiber in commercial and enterprise networks due to its reliability, durability, and performance characteristics.

​

​

When Fusion Splicing Is Used

 

Fusion splicing is used in a wide range of fiber optic applications where permanent, low-loss connections are required.

​

Fusion splicing is commonly performed for:

• Fiber optic backbone installations

• Building-to-building fiber connections

• MDF to IDF fiber links

• Fiber cable repairs and restorations

• Network expansions and relocations

• High-count and high-density fiber systems

Fusion splicing provides long-term stability and is ideal for critical network infrastructure.

​

​

Single-Mode & Multimode Fiber Fusion Splicing

 

FIS performs fusion splicing for both single-mode and multimode fiber, selecting splicing procedures based on fiber type, application, and performance requirements.

 

Supported fiber types include:

• Single-mode fiber (OS2)

• Multimode fiber (OM3 and OM4)

• Indoor and outdoor fiber cable

• Backbone and distribution fiber

• Armored and loose-tube fiber

Each splice is completed using calibrated fusion splicing equipment to ensure accuracy and consistency.

​

​

Fusion Splicing for Fiber Backbone & Distribution Networks

 

Fusion splicing plays a critical role in fiber backbone and distribution network construction. Properly executed splices ensure signal integrity across long distances and high-capacity fiber pathways.

 

Our backbone fusion splicing services include:

• Splicing for MDF and IDF connections

• Vertical riser fiber splicing

• Campus and building-to-building fiber splicing

• High-fiber-count backbone systems

• Splice enclosure and tray installation

All splices are organized, protected, and documented to support long-term network maintenance.

​

​

Fusion Splicing for Fiber Repair & Restoration

 

Fusion splicing is the standard method for repairing damaged or cut fiber optic cables. Accurate splicing minimizes loss and restores service quickly.

 

Our fiber repair splicing services include:

• Emergency fiber restoration

• Fiber break and damage repair

• Splicing for outdoor and underground fiber

• Temporary and permanent fiber repairs

• Support for troubleshooting and testing

Fusion splicing allows damaged fiber to be restored with minimal impact on network performance.

​

​

Fusion Splice Protection & Enclosures

 

Proper splice protection is essential to maintain fiber integrity after splicing.

 

FIS installs:

• Heat-shrink splice protection sleeves

• Splice trays and organizers

• Fiber splice closures and enclosures

• Indoor and outdoor rated splice housings

Splice protection prevents mechanical stress, moisture intrusion, and long-term degradation.

​

​

Fusion Splicing Quality Control & Testing

 

All fusion splicing work is performed with quality control and verification procedures.

​

Our quality assurance process includes:

• Visual inspection of splice quality

• Splice loss estimation during fusion

• OTDR testing and verification when required

• Documentation of splice locations and counts

Testing confirms that splices meet performance expectations before the network is placed into service.

​

​
