Coriant and Allied Fiber Announce Successful 1 Terabit Super-Channel Trial

Coriant and Allied Fiber today announced the successful completion of a 1 Terabit-per-second (Tbps) super-channel transmission trial over a 1,700 km fiber optic ring connecting West Palm Beach to Jacksonville, Florida, using Coriant's innovative FlexiGrid technology through Allied Fiber’s Technology Showcase located within Allied Fiber’s open access, integrated, network-neutral colocation and dark fiber superstructure. Allied Fiber’s Technology Showcase sits within its Southeast Florida segment that covers more than 360 miles throughout the state of Florida and is available to all third-party network operators. The Coriant hiT 7300 Multi-Haul Transport Platform live-trial has been established to show network operators how the Coriant solution works together with the Allied Fiber infrastructure to enable connections between access networks, including fiber and wireless, through to long-haul carrier, content and enterprise networks through points of interconnection within the Allied Fiber system.

The terabit field trial was conducted on Allied Fiber’s Southeast Florida segment using commercially available hardware and pre-commercial software, over Allied Fiber's new Corning fiber. The trial demonstrated 1 Tbps super-channel transmission in a 368.7 gigahertz (GHz) grid over 1,700 km. In addition, it showed a greater than 35 percent improvement in spectral efficiency which significantly increases the capacity of the system compared to conventional fixed grid technology.

The trial also demonstrated the flexible allocation of the 1 Tbps super-channel by placing it in three separate locations within the C-band, thus maximizing the usability of existing fiber resources. This capability comes with an improved spectral efficiency of 3.4 bits per second per Hertz (b/s/Hz) and provides a maximum fiber capacity of 13 Tbps over a distance of 1,700 km on field-installed fiber while using commercial-grade equipment.

"We are pleased to team with Allied Fiber to demonstrate the value that next-generation optical networking technologies can bring to broadband users," said Pat DiPietro, CEO, Coriant. "We are committed to helping our partners like Allied Fiber meet the capacity requirements of residential and business end-user services with systems capable of seamless and efficient scalability to 1 Terabit per channel and beyond."

"We are excited with the results of the trial with Coriant on our network-neutral infrastructure," said Hunter Newby, CEO of Allied Fiber. "It highlights how our new Corning SMF 28e+ fiber has performed carrying 1 Terabit transmission which should be encouraging news for all network operators looking to light their own transport route both for the capabilities of the technology and for the availability of the long-haul dark fiber to run it on."

The trial demonstrates Allied Fiber’s desire and ability to highlight the most efficient and scalable technology in the market. Coriant’s FlexiGrid technology is based on an adaptive channel grid with wavelengths dynamically selected based on the data rate. By increasing channel density, FlexiGrid technology enables network operators that utilize Allied Fiber’s neutral colocation and dark fiber infrastructure greater service agility and network flexibility.

Coriant is a strategic supplier of optical transmission equipment and management systems to Allied Fiber for their mutual customers. The company also provides specialized optical networking support services including design, logistics, installation, commissioning, local pre-deployment system testing and maintenance.
