Infinera trial transmits 800G over 950km
Infinera has completed a live network trial of 800Gb/s single-wavelength transmission at 96GBd over 950km across a long-haul link in a major North American network operator’s production network.
The trial featured the company’s sixth-generation dual-800G Infinite Capacity Engine (ICE6) technology, and the company says that the achievement is a milestone in driving down the cost-per-bit of telecommunications networks.
The network trial demonstrated the ability of the 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. These services could prove essential in ensuing business continuity during difficult operating conditions such as those currently experienced globally.
The production network trial was conducted over a third-party optical line system carrying live multi-vendor traffic. It was implemented using Infinera’s Groove (GX) Series disaggregated platform, equipped with an ICE6-based sled over industry-standard G.652 fibre. The results demonstrated the performance value of the 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.
Parthi Kandappan, chief technology officer at Infinera explained: ‘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.’
Earlier this month, Infinera teamed up with Corning to achieve an 800G single wavelength using the former's sixth-generation Infinite Capacity Engine (ICE6) technology across 800km on the latter's TXF optical fibre.
