Coriant and Allied Fiber Test 1 Terabit Super-Channel

Coriant and Allied Fiber successfully transmitted a 1 Terabit-per-second (Tbps) super-channel over a 1,700 km fiber optic ring connecting West Palm Beach to Jacksonville, Florida.

The terabit field trial was conducted on Allied Fiber’s Southeast Florida segment using the commercially available Coriant hiT 7300 Multi-Haul Transport Platform 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.

Coriant said 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."

Allied Fiber, which was founded in 2008, offers a combination of long-haul and multi-access point, short-haul fiber coupled with its own colocation facilities that provide control of the underlying physical assets to its network operator customers.
