Verizon cites week-over-week rise in traffic

Verizon reported the following week-over-week comparisons of peak hour usage traffic over its residential fiber and wireless consumer networks:

  • Gaming, up 75%
  • VPN, up 34%
  • Web traffic up close to 20%
  • Video, up more than 12%
  • Social media usage: 0%, flat

Verizon said usage is expected to fluctuate over time, especially as more people telecommute and more students are at home.

“As we see more and more individuals work from home and students engage in online learning, it is a natural byproduct that we would see an increase in web traffic and access to VPN.  And as more entertainment options are cancelled in communities across the US, an increase in video traffic and online gaming is not surprising,” said Kyle Malady, Chief Technology Officer for Verizon.  “We expect these peak hour percentages to fluctuate, so our engineers are continuing to closely monitor network usage patterns 24x7 and stand ready to adjust resources as changing demands arise.”

“We’re in an unprecedented situation,” said Malady. “We continually evaluate peak data usage times and build our networks to stay ahead of that demand.  “While it is not clear yet how having millions of additional people working from home will impact usage patterns, we remain ready to address changes in demand, if needed.”

Infinera carries 800G wavelength at 96 Gbaud over 950km

Infinera completed a live network trial of 800G single-wavelength transmission at 96 Gbaud over 950 kilometers (km) across a long-haul link in a major North American network operator’s production network.

The production network trial, which was conducted over a third-party optical line system carrying live multi-vendor traffic, leveraged Infinera’s Groove (GX) Series, equipped with its sixth-generation dual-800G Infinite Capacity Engine (ICE6) technology.  The trial demonstrated 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 operator's network used G.652 fiber.

Infinera said the achievement signals a major industry milestone in driving down the cost per bit of telecommunications networks.

“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,” said Parthi Kandappan, Chief Technology Officer at Infinera. “This marks another major accomplishment for Infinera’s Optical Innovation Center, adding to its long history of pioneering innovations in optical networking.”

Infinera and Corning carry 800G wavelength over 800km

Infinera has demonstrated the ability to carry an 800 Gbps wavelength across 800km on Corning’s TXF optical fiber.

The achievement leveraged Infinera’s sixth-generation Infinite Capacity Engine (ICE6) technology in a Groove (GX) Series platform transmitting 800G using 64QAM with probabilistic constellation shaping (PCS). ICE6 combines Infinera’s sixth-generation photonic integrated circuit with its in-house-developed 7-nanometer dual-channel 800G per-wave FlexCoherent digital signal processor.

Corning’s state-of-the-art TXF fiber is an ITU-T G.654.E compliant, ultra-low-loss, silica-core fiber with large effective area.

The companies said the success of the 800G trial highlighted the advanced features of Infinera’s vertically integrated ICE6 technology, including Nyquist subcarriers, per-subcarrier long-codeword PCS, and per-subcarrier dynamic bandwidth allocation, along with superior fiber designed to help meet growing bandwidth demands for network operators from metro to subsea network applications.

NeoPhotonics intros 64 GBaud L-band coherent optical components

NeoPhotonics introduced an L-Band suite of coherent optical components, including its 64 GBaud L-Band High Bandwidth Coherent Driver Modulator (HB-CDM), 64 GBaud L-Band Intradyne Coherent Receiver (ICR) and ultra-narrow linewidth L-Band tunable laser Micro-ITLA. NeoPhotonics already supplies standard C-Band coherent components.

NeoPhotonics notes that the L-Band uses wavelengths centered around 1590 nm and is primarily used to complement the C-Band (1550 nm) to increase data capacity, especially in long-haul networks. By adding channels in the L-Band, operators can double the capacity of an optical fiber. NeoPhotonics 64 Gbaud coherent components and tunable lasers enable single channel 600G data transmission over short haul data center interconnect (DCI) links using 64 QAM. These components also support 400G over metro distances of 400-600 km using 64 GBaud and 16 QAM or 200G over long-haul distances of greater than 1000 km using 64 GBaud and QPSK.

The NeoPhotonics L-Band External Cavity (ECL) micro-ITLA incorporates the same laser architecture as its C-Band laser for a pure optical signal with an ultra-narrow linewidth and very low phase noise. In coherent systems, any error in the phase of the signal and reference lasers, due to the laser’s linewidth, can cause data errors, thereby making narrow linewidth critical in systems using higher order modulation.

The NeoPhotonics 64 Gbaud L-Band HB-CDM co-packages an Indium Phosphide based Mach-Zehnder (MZ) quadrature modulator chip with a linear, quad-channel, differential 64 GBaud driver. Both the C-Band and L-Band versions of the HB-CDM are designed to be compliant to the Optical Internetworking Forum (OIF) Implementation Agreement OIF-HB-CDM-01.0 “High Bandwidth Coherent Driver Modulator”.

NeoPhotonics 64 Gbaud L-Band Micro-ICR incorporates an integrated comixer chip and four balanced photodiodes with four differential linear amplifiers to provide four output channels at 64 GBaud. The form factor of the High Bandwidth Coherent Receiver is designed to be compliant with the OIF Implementation Agreement for Micro Integrated Intradyne Coherent Receivers; IA # OIF-DPC-MRX-02.0.

For applications that require more capacity than provided by the standard C-Band, but do not require the full L-Band, each of these components is available in a “C++” version, which supports tuning across the full “Super C-band” covering 6.0 THz of spectrum or up to 50 percent more than standard systems. These C++ components can support 80 channels at 75 GHz channel spacing, which effectively increases the capacity of an optical fiber by as much as 50 percent over standard C-Band only systems at comparable distances.

"We are pleased to add L-Band versions to our existing suite of coherent components, thus providing customers with a complete solution to their fiber capacity requirements, whether C-Band, C++ Band or L-Band," said Tim Jenks, Chairman and CEO of NeoPhotonics. "Our ultra-pure tunable laser design and our high performance coherent modulator and receiver designs are very flexible and excel in different spectral regimes to provide the highest speed over distance performance," concluded Mr. Jenks.

Nutanix tunes for Big Data and Analytics

Nutanix has added new capabilities for big data and analytics applications, as well as unstructured data storage.

Nutanix Objects 2.0 includes the ability to manage object data across multiple Nutanix clusters for achieving massive scale, increased object storage capacity per node, and formal Splunk SmartStore certification. The enhancements add to a cloud platform that is already optimized for big data applications, to deliver performance and incredible scale, while also reducing cost by maximizing existing, unused resources.

"Digital transformation requires web-scale storage for enterprise workloads. Object storage is rapidly becoming the storage of choice for next gen and big data applications. As object storage makes the leap from the cloud to the datacenter and mission critical workloads, economics must be balanced with performance," said Amita Potnis, research director in IDC's Storage team. "Nutanix is known for flexibility and simplicity. Multi-cluster support and certification with Splunk SmartStore with Nutanix Objects will allow for massive scale at the right price and performance that these workloads require."

New features for running big data workloads, include:


  • Increased scale-out object storage -  multi-cluster support to deliver massive scale object stores. Breaking down cluster boundaries enables teams to leverage a single namespace across multiple Nutanix clusters, managed from a single console. It also allows IT teams to take advantage of unused storage capacity anywhere in their Nutanix environment to improve storage economics.
  • Deeper storage nodes -  In addition to new scale-out capabilities, Nutanix Objects 2.0 now supports deeper, high-capacity nodes with up to 240TB of storage. This enables multi-petabyte objects stores with a single Nutanix cluster.
