Vodafone and Huawei Test 2 Tbps WDM


Vodafone and Huawei have successfully tested 2 Terabit per second optical transmission over a 3,325km span on Vodafone's live network. The field trial achieved a capacity 20-times higher than current commercially deployed 100 Gbps systems.

Specifically, Huawei reported a test achieving 2 Tbps with transmission distance of 1500 km using a super-channel PDM-16QAM-based high spectral efficiency solution.

A second test achieved a transmission distance of 3325 km using a super-channel Nyquist PDM-QPSK-based ultra-long-haul solution. Both transmissions were on a link with G.652 fibers and erbium-doped fiber amplifiers (EDFAs) without electrical regeneration. The link used in the trial was on Vodafone's backbone network, passing through a few cities in Germany.

"We are at the forefront of global 100G deployments, and have taken the lead in delivering key breakthroughs in technologies beyond 100G. Through collaboration with Vodafone and other leading international operators and customer-centric R&D, Huawei is always ready to build advanced optical networks for customers," said Jack Wang, president of Huawei's transport network product line.

  • In July 2012, Huawei announced a prototype WDM platform capable of delivering 2 Tbps per-channel -- a 20–fold increase over the 100G channels available today. Huawei has previously demonstrated 400 Gbps technology at trade shows earlier this year.
  • The 2 Tbps channel rate is achieved by using intelligent digital signal processing and high performance adaptive-SD FEC technologies. Huawei claims that the 2T signals with 300GHz spectral width can transmit over a distance of 1,000 km without electrical regeneration when using G.652 fiber and common EDFAs.
  • The use of 2 Tbps channels expands the prototype WDM system capacity to 56 Tbps when utilizing wavelengths in both the C and L bands.
  • At the time, Huawei said it was also planning to use flex transceiver technology on this prototype WDM platform. This will enable software-defined OTN, allowing a programmable network controller to configure parameters such as the number of subcarriers, subcarrier spacing, modulation codes and FEC modes, thereby achieving flexible adjustments in areas including line rates, transmission distances and transmission capacity. Huawei describes this as programmable "resilient tunnels".

Akamai State of the Internet Report: Global Average Connection at 2.8 Mbps

The global average connection speed decreased by approximately seven percent between the second and third quarters of 2012 to 2.8 Mbps, according to Akamai's newly released Third Quarter, 2012 State of the Internet report.

The Akamai report, which uses data collected from its platforms deployed worldwide, provides insight into key global statistics including connection speeds, attack traffic, and network connectivity and availability, among many others.  This edition provides additional analysis on the Operation Ababil DDoS attacks against the banking industry in the United States and an examination of mobile browser usage by network connection type.

Some highlights:

  • Akamai connected with more than 680 million IPv4 addresses from 243 countries/regions during Q3 2012, up 11 percent increase year over year.
  • Akamai estimates that over one billion unique web users connected to its platform during the quarter.
  • China remained the single largest volume source of observed attack traffic at 33%, followed by United States at 13%, and Russia at 4.7%.
  • "Operation Ababil", the DDoS attack against U.S. banks that occurred in September 2012, generated up to 65 Gbps of total attack traffic that varied in target and technique. A significant portion (nearly 23 Gbps) of the attack traffic was aimed at the Domain Name System (DNS) servers that are used for Akamai's Enhanced DNS services.
  • Akamai observed global broadband (>4 Mbps) and high broadband (>10 Mbps) adoption showing solid gains in the quarter. The global high broadband adoption rate grew by 8.8 percent quarter over quarter, reaching 11 percent, while the global broadband adoption rate increased 4.8 percent, growing to 41 percent.

The full report is available online.
