Fiber optic splice boxes are protective enclosures used in fiber optic networks to house and consolidate optical fiber splices and connections. Properly installed splice boxes are critical components that allow fiber optic networks to be efficiently expanded and maintained. This article provides an in-depth overview of fiber optic splice boxes, with a focus on products from the leading manufacturer Fibermint. We will examine what splice boxes are, types of Fibermint boxes, key selection criteria, installation best practices, and maintenance.
What are Fiber Optic Splice Boxes?
A fiber optic splice box, also called a fiber splice closure or splice case, is a container used to protect optical fiber splices and connections. It organizes and stores fiber slack and splices in a central, accessible location.
The main functions of fiber optic splice boxes include:
- Protecting splices - The enclosure seals out contaminants and mechanical damage that can degrade fiber signals. common protection ratings used are IP54 and IP68.
- Accessibility - Technicians can safely access the interior to perform maintenance like reconfiguring or troubleshooting splices.
- Organization - Internal trays, anchors and guides organize incoming/outgoing cables and individual fibers neatly.
- Managing slack - Fiber coils allow for rearrangements and repairs without pulling new cable.
- Strength member anchoring - The box secures the fibers' Kevlar strength members to prevent cable movement from stressing the glass fibers.
- Consolidation - Multiple distribution or drop cables can be spliced together in one location.
Overall, splice boxes create stable splice points and flexibility for modifying fiber connections as needed. This beats risky handling of unprotected splices in the field.
Types of Fibermint Splice Boxes
Fibermint manufactures a comprehensive range of high-quality fiber optic splice boxes to meet different network requirements:

Fibermint can also design fully customized splice box solutions where needed.
Key Splice Box Selection Considerations
Choosing the right fiber optic splice box depends on factors like the deployment environment, space and capacity needs. Considerations include:
Installation Environment
Where will the splice box be placed - outdoors, direct buried, indoors, aerial, or underground? Environmental sealing and temperature tolerance are important.
Space and Capacity
Evaluate the dimensions, number of splices, and cable entry ports needed now and for future growth. This determines the required box size.
Accessibility
How will technicians access the box? Removable domes and doors allow easy re-entry. Underground handholes require confined space procedures.
Cable and Fiber Management
Review internal cable routing paths and anchor points. Fiber organize trays should be removable and reconfigurable.
Security
Outdoor boxes need tamper-resistant, lockable covers. Monitoring may be needed for remote boxes.
Sealing and Protection
Will the box be submerged or directly buried? IP68 rating or better is recommended.
Budget
Higher quality boxes cost more but offer extended lifetimes. Prioritize critical links.
By balancing these criteria, the ideal fiber optic splice box can be matched to the network's specific demands.

Splice Box Installation Best Practices
Following careful installation procedures ensures fiber optic splice boxes achieve their maximum reliability and lifetime:
- Thoroughly clean and prepare cables using alcohol wipes.
- Leave plenty of fiber slack when routing and splicing within the box.
- Securely anchor the cable Kevlar strength members to prevent movement.
- Organize fibers neatly into labeled splice trays for easy maintenance.
- Tighten all cable glands and seals to prevent moisture ingress.
- Avoid sharp cable bends which stress glass fiber. Maintain bend radius.
- Test all fibers to ensure low insertion loss before closing the box.
- Backfill underground boxes with clean sand or grit to prevent housing cracks.
- Seal any unused cable ports with plugs to keep the enclosure protective class.
Proper training on box installation best practices is highly recommended. This maximizes the box's cable management capabilities while providing a clean and accessible interior for splice work.
Ongoing Splice Box Maintenance
Regular inspection and maintenance keeps splice boxes performing optimally:
- Establish a preventative maintenance schedule based on environmental factors and box criticality.
- Check sealed for cracks or gaps where moisture or contaminants could enter. Re-seal as necessary.
- Confirm cable glands are snug and all unused ports are plugged.
- Test fiber splices for insertion loss changes indicating degrading splices. Re-splice if needed.
- Verify anchor strength member ties are secure and not degrading.
- Inspect for any signs of water intrusion, rodent damage, or pulled fibers.
- Update labeling and organization if modifications were made.
- Lubricate and exercise box seals and doors to prevent seizing up over time.
Following the manufacturer's maintenance guidelines for regular inspection, testing, and re-sealing preserves long-term splice box integrity.
