Transform your network with fiber connectivity

Your business-critical data relies on network performance. Transform your network by upgrading to fiber connectivity, which can enhance productivity, customer satisfaction, security, and cost management. Fiber uses light waves instead of electrical signals to transmit data, allowing higher volumes of information to be sent over longer distances at faster speeds. Fiber also supports equal upload and download speeds and is faster than traditional cable internet connections. Propel your network and your business to new heights with fiber connectivity.

Reliable and resilient

Resistant to fire, electromagnetic interference, and radio signals—so you can be confident your network will stay connected.

Faster speeds, greater capacity

With upload speeds as fast as downloads, fiber enables faster file transfers, smooth online meetings, and lower lag across your operations. 

Security built-in

Transmits voice and data signals via pulses of light, which are difficult to intercept.

The benefits of fiber

Download speed
With download speeds up to 1Tbps, fiber optic internet can deliver the fastest speeds available.
Upload speed Fiber can provide equal upload and download speeds, which is important for apps like streaming and VoIP. 
Latency¹ Fiber internet has low latency to make cloud services and applications more responsive.
Reliability Fiber is not susceptible to disruption by flooding or electromagnetic interference making it highly reliable.²
Security Fiber doesn’t emit interceptable signals, making it highly secure.³
