High Capacity. Low Latency. Bandwidth to Spare.

Connect regionally, locally and nationally with our high-capacity reliable, fibre network.

CenturyLink® Optical Transport Services are designed for customers who prefer control over their data through private networking. Optical transport enables organizations to enjoy greater flexibility than other transport options because of the transparent characteristic of wavelengths, which means customers may transport a wide variety of protocols to meet their business needs.

Simple, Private, Secure
Businesses today run on data, so securing your sensitive data is a critical concern. CenturyLink optical transport solutions can help you send data with confidence, bypassing public networks. CenturyLink managed equipment and fibre is supported by network security professionals who monitor and surveil network activity to help ensure the integrity of customer connections.

Higher Performance
High-speed, low-latency connections support time-sensitive applications and provide reliable, predictable performance.

Greater Flexibility
Optical wavelengths provide transparency to higher-layer protocols, simplifying the need for multiple connections.

Proven expertise in managing network solutions, including account management, sales engineering, service delivery and network operations professionals that provide support to all aspects of your Optical Services.

Flexible Designs for High-Bandwidth Needs
Our solutions include options for multiple interfaces, network configuration and bandwidths up to 100 Gbps.

Optical Wavelength Service
Due to the rapid growth of the Internet, applications, centralized architecture and e-business, it seems you can never have enough bandwidth. Now you can get the capacity you need at a price you can afford with our highly reliable, private, point-to-point service delivered over a next-generation Converged Optical Service Platform (COSP). This solution delivers a dedicated transport network without a large capital outlay or the responsibility of owning and operating network infrastructure. Designed to support redundancy needs and diverse routing requirements, Optical Wavelength Service is an ideal solution for disaster recovery and business continuity applications.

For businesses who require more advanced ring configurations connecting multiple locations, GeoMax provides a custom solution to meet those needs. GeoMax offers multiple interfaces needed for customer connections between data centres, campus environments and branch offices. The GeoMax solution provides fully dedicated facilities including equipment and fibre to support customer networking needs. The service is supported by a full-time network operations centre dedicated specifically for GeoMax customers.

Designed with Flexibility to Meet Your Specific Connectivity Needs

Whether you need a custom data transport solution or massive bandwidth, you can get it with Optical Transport Service.

Optical Wavelength Service Network Coverage

Optical Wavelength Service
Optical Wavelength Service is a private, optical point-to-point circuit service with predictable, low-latency performance available in large bandwidth increments (1 Gbps to 100 Gbps). The service has optional interfaces of Ethernet, SONET or OTN and is transparent to higher protocols such as IP.

  • Security
    This optical solution is designed for the highest level of security and performance to meet business-critical applications. CenturyLink wavelength solutions do not use IP routing tables like other services, and are completely private networks, minimizing the risk of intrusion and Denial of Service attacks by others. With wavelength services, there is no sharring of resources, each customer has their own private connection.
  • Reliability
    Designed to perform at 99.9% and above availability, depending on configuration
  • Flexibility
    Optical wavelengths provide customer flexibility by supporting multiple Interfaces to meet their networking and business application needs. They include Ethernet, SONET, OTN and Storage Area Networking (SAN) protocols.

Ease of management
Monitored 24/7 network control centre includes fault management of network transport alarms, surveillance, dispatch and fix verification/tracking

Optional Features
Support custom routing requirements (for example, diverse routing needs that are subject to available network facilities) as well as protection switching
