How to Choose the Right Expanded Beam (EB) Connector for Outdoor FTTX Applications
As FTTX networks continue to expand into outdoor, harsh, and hard-to-access environments, the demand for rugged, low-maintenance fiber optic connectors has never been higher. Traditional physical-contact fiber connectors often struggle with dust, moisture, frequent mating, and field installation challenges.
The TBE Expanded Beam (EB) Connector Series is specifically designed to address these challenges. With multiple product options—EB-11 Series, EB-13 Series, and EB-15 Series—selecting the right connector depends on your application environment, fiber count, and mechanical requirements.
This guide explains how to choose the right EB connector for your outdoor FTTX deployment.
Why Choose Expanded Beam Connectors for FTTX?
Expanded Beam (EB) technology uses precision optical lenses to expand and collimate the light beam, enabling non-contact optical transmission. This provides major advantages for outdoor FTTX networks:
-
Resistant to dust, dirt, and moisture
-
Stable optical performance under vibration and temperature variation
-
Reduced cleaning and maintenance requirements
-
High mating durability for repeated connect/disconnect operations
-
Ideal for outdoor, aerial, underground, and pole-mounted installations
The TBE Expanded Beam Series delivers these benefits in a waterproof, field-proven connector design.
Key Factors When Selecting an EB Connector
1. Installation Environment
Consider whether the connector will be used in:
-
Outdoor cabinets or closures
-
Aerial or pole-mounted FTTX systems
-
Underground or roadside infrastructure
-
High-humidity, dusty, or coastal environments
All TBE Expanded Beam connectors are designed for outdoor waterproof performance, but mechanical size and robustness vary by series.
2. Connector Size & Mechanical Robustness

3. Waterproof & Environmental Protection
All TBE Expanded Beam connectors support outdoor waterproof performance, with sealing designs suitable for rain, humidity, dust, and temperature extremes. This makes EB-11 Series, EB-13 Series, and EB-15 Series ideal for long-term FTTX network reliability.
4. Maintenance & Lifecycle Cost
Expanded Beam connectors significantly reduce cleaning frequency compared to physical-contact connectors. For large-scale outdoor FTTX networks, this translates to:
-
Lower operational cost
-
Faster installation and maintenance
-
Reduced risk of network downtime
Typical FTTX Applications
-
Outdoor fiber distribution points
-
Pole-mounted and aerial FTTX networks
-
FTTA / access network infrastructure
-
Remote and rural broadband deployments
-
Industrial and utility communication networks
Choosing the Right TBE Expanded Beam Connector
| Application Requirement | Recommended Series |
|---|---|
| Compact outdoor enclosures | EB-11 Series |
| General outdoor FTTX use | EB-13 Series |
| Harsh or heavy-duty environments | EB-15 Series |
Conclusion
Selecting the right Expanded Beam connector is essential for ensuring long-term reliability and performance in outdoor FTTX networks. The TBE Expanded Beam Series, including EB-11 Series, EB-13 Series, and EB-15 Series, provides scalable solutions to match different installation environments and durability requirements.
By choosing the appropriate EB connector, network operators can reduce maintenance costs, improve network uptime, and ensure stable optical performance in even the toughest outdoor conditions.
