Infinera breaks record with 800G transmission over 950km in live network trial
Infinera Corp of Sunnyvale, CA, USA, a vertically integrated manufacturer of digital optical network systems incorporating its own indium phosphide (InP)-based photonic integrated circuits (PICs), has completed a live network trial of 800Gb/s single-wavelength transmission at 96Gbaud over 950km across a long-haul link in a major North American network operator’s production network.
Powered by Infinera’s sixth-generation dual-800G Infinite Capacity Engine (ICE6) technology, the achievement is claimed to signal an industry milestone in driving down the cost per bit of telecoms networks. The trial showcased the ability of Infinera’s 800G technology to enable network operators to rapidly and cost-effectively address the increasing capacity demands of new services such as 5G, enhanced broadband, and cloud-based business services.
Conducted over a third-party optical line system carrying live multi-vendor traffic, the production network trial was implemented using Infinera’s Groove (GX) Series, equipped with an ICE6-based sled over industry-standard G.652 fiber. The results of the trial demonstrated the performance value of Infinera’s vertically integrated ICE6 optical engine, which features second-generation Nyquist subcarriers, 64QAM with per-subcarrier long-codeword probabilistic constellation shaping, and per-subcarrier dynamic bandwidth allocation.
“The success of this trial proves our ability to transmit 800G high-baud-rate signals across significant distances, which will be instrumental in driving down network costs,” says chief technology officer Parthi Kandappan. “This marks another major accomplishment for Infinera’s Optical Innovation Center.”
