Logix Fiber Networks has deployed multiple 400G wavelength services to one of the nation’s largest wireless carriers in Texas, a growing market for wireless and data centers.

The deployment on an 800G backbone provides the carrier with scalable and diverse backbone connectivity to support its growing wireless traffic demands.

This agreement represents the largest wavelength backbone deal Logix has delivered to a wireless carrier to date.

Jim Hintze, chief revenue officer at Logix Fiber Networks, said he expects wireless operators’ wavelength demands to accelerate. “This is the first 400G deployment for our wireless wholesale customers, with more to come,” he said.

Focus on diversity

Logix’s new backbone connections establish inter-market diversity throughout Texas, connecting the state’s major metro areas.

Designed with survivability in mind, the deployment ensures that cellular traffic remains online and uninterrupted, even in the event of a fiber cut or network disruption.

The service provider’s network design provides redundancy and low-latency performance to support 5G growth and next-generation wireless services across the region.

“By investing in expanded backbone capacity and diverse long-haul routes between Texas’s largest markets, Logix continues to strengthen the reliability and resiliency of the state’s communications infrastructure,” Hintze said.

A growing network

Logix’s statewide fiber network spans more than 300,000 fiber miles, with more than 3,000 on-net buildings, data centers and connections to more than 80 data centers across Texas.

Network upgrades continue to be a priority for Logix to serve not only wireless operators, but also data centers.

Earlier this year, the service provider made upgrades to data centers in Austin and Dallas.

In Austin, Logix expanded its fiber network to support data centers in various communities, including Round Rock and Pflugerville. This expansion enables connectivity for key data centers such as Switch Round Rock, Sabey Round Rock, and Skybox Pflugerville.

Over in Dallas, Logix expanded its network capacity to 400G at two DataBank data centers in the Dallas metro area. The timing of the DataBank upgrade was key as the data center provider secured a $2 billion investment to accelerate expansion across its footprint of more than 65 data centers in 27 markets.

DataBank will use the funding will finance growth, including three new data center campuses announced over the past year: a 480MW hyperscale campus in South Dallas and two additional large-scale campuses in Virginia and Georgia.
