Verizon Carries 21.7 Terabits per second over Single Fiber with NEC

In a trial performed earlier this year on 1,503 kilometers (934 miles) of standard single mode field fiber in the Dallas area, Verizon successfully transmitted 21.7 terabits per second (Tbps) -- the highest capacity to date under field conditions.


NEC was the equipment supplier for the trial, which was described in a post-deadline paper presented at the recent OFC/NFOEC Conference and Expo in Los Angeles.


NEC said the terabit capacity was achieved by increasing modulation levels and reducing optical carrier spacing using superchannels. This trial also used a novel approach that allowed for different modulation formats to be used to help ensure signal performance while carrying the highest total capacity. The two companies also specifically focused on transmission performance over a significant fiber distance since other experiments in this area have only been performed in a lab environment.


In 2011, Verizon and NEC Corporation of America completed an industry first by successfully transmitting high bit-rate technologies, including 100G, 450G and 1T, coexisting on the same fiber in a joint field trial.


"Verizon continues its research to find the scientific limits of high-capacity optical technology as we strive to offer the most advanced network technology that adds long-term value to our customers and is capable of sustaining the tremendous growth potential," said Ihab Tarazi, vice president of global IP and transport planning and technology for Verizon. "This joint effort moves the industry toward a better understanding of the technology's challenges, differentiators and viability because the future will be shaped by what we learn now."http://www.verizon.nethttp://www.nec.com

OKI Develops Adaptive GE-PON + 10 GE-PON System

OKI announced an adaptive network configuration technology for channel-switching between current GE-PON systems and next generation 10 GE-PON systems. The goal is a flexible, low-cost optical access system for subscription-based 100-km broadband optical networks.


OKI said its adaptive networking builds network infrastructure in a ring or cascade form by using centralized control node and passive OHF for the PON system, which was conventionally branched by power splitters. This enables broadband technology with lowed loss resulting from branching. Centralized control nodes switch WDM and OCDM channel allocating, realizing virtual technology in a logical star form without depending on physical connection of OLT and ONU.


This experiment demonstrates the transmission of WDM and OCDM hybrid optical signals, restoration via passive routing, and service provisioning from GE-PON to 10G-EPON without obstacles to other users.


Moving forward, OKI will continue to develop multi-channel control and OLT driving control technologies to offer more efficiency and build virtualized access system technology by combining this adaptive networking technology for an early practical realization for virtual PON system.


"The adaptive network configuration technology developed by OKI combines OKI's unique optical hybrid filtering (OHF3) and adaptive networking technologies for flexible connections between OLT and ONU," says Takeshi Kamijoh, General Manager of Research and Development Center at OKI. "In addition to wavelength-division multiplexing (WDM) used for metro-core networks, OHF realizes multiple expansion technology that enables 'add/drop' from 160ch multiple signals by adding optical code division multiplexing (OCDM) technology, achieving filters with low transmission loss."http://www.oki.com

Fujitsu Develops DSP Algorithm for 100G Long-haul Optical Distortion

Researchers at Fujitsu have developed a digital signal processing algorithm to compensate for waveform distortion in long-haul transmission systems operating over several hundred kilometers. The method is aimed at 100 Gbps transmissions, which tend to suffer from waveform distortion caused by nonlinear optical effects over distance.


Fujitsu said a key advantage of its new technology is that it does not require signal regenerators. The nonlinear compensation technology can restore the signal received with distortion to a clean waveform.


The company claims roughly a twenty-fold improvement in the compensation ability per circuit size compared to typical existing technology. The design also cuts the energy consumption of compensation circuits by two-thirds.


The receiving-side digital signal processing LSI used to measure and verify the effectiveness of the developed technology was developed under a project sponsored by Japan's Ministry of Internal Affairs and Communications.


The new technology takes a new approach in that it transmits additional inverse distortion in order to "clean up" distorted waves. Unlike receiver-end compensation circuits, waveforms from compensation circuits located on the transmission end do not contain noise or distortion, thereby enabling simpler computation. Fujitsu has narrowed its focus on DP-QPSK modulation.


Fujitsu reported that in a transmission test at 112 Gbps, the new technology was shown to achieve, using a one-stage circuit, even higher signal quality than that obtained using a 20-stage compensation circuit in conventional technology.

Narus Cyber Survey: Increase in Volume and Sophistication of Attacks

Network security professionals are expressing concern at the increase in volume and sophistication of attacks, according to a newly published annual cyber security survey sponsored jointly by Narus, Converge! Network Digest and GSN: Government Security News. The annual survey queries a focus group comprising security professionals in a variety of industries.

Some key findings:

  • More than 55 percent of respondents are concerned that their company is not equipped to protect its networks from cyber attacks; approximately 85 percent think the government is not equipped to protect its networks.


  • The overwhelming majority of respondents (93.8 percent) believe cyber attacks are on the rise.


  • Inability to protect sensitive and confidential data (64.6 percent), viruses and malware (62.5 percent), social media attacks (52.1 percent), being able to analyze threats in real time (50 percent) and zero-day attacks (47.9) all ranked high as significant threats to organizations today.


  • More than 79 percent of the respondents believe the best way to protect against cyber attacks is with a solution that detects, analyzes and mitigates unwanted, unwarranted or malicious traffic in real time.


  • The respondents believe that the following three factors are most important when evaluating a cyber security solution: detection and remediation of advanced persistent threats, detection of bots and real-time threat analysis.
    Government networks left vulnerable.


  • Once again, the majority of respondents this year feel cyber attacks are showing no signs of slowing; in fact, the actual percentage held steady at 93.8 percent of respondents (as compared with 93 percent in 2010). Inability to protect sensitive data, viruses, malware and inability to analyze threats in real time present the biggest threats, according to respondents. The increasing sophistication of attacks is also worrying 91.7 percent of respondents, no doubt due to the onslaught of advanced persistent threats (APTs) like non-signature attacks.


  • The survey indicates that companies are bolstering their cyber security efforts, and therefore the confidence of their employees. Indeed, the number of respondents concerned that their company is not well-equipped to protect against cyber attacks has slipped over the past year (55 percent in 2011 vs. 71 percent in 2010), suggesting that companies are now at least beginning to implement technology that stands up to sophisticated threats. Additionally, 42.6 percent of respondents indicated that their companies have increased their respective cyber security budgets since 2010. But the same respondents were not so confident in the government's ability to protect its networks. Eighty-five percent of respondents believe government networks remain vulnerable to cyber attacks.


  • The survey also supports the view that there is a pressing need for real-time detection, analysis, and mitigation of cyber threats. Almost 80 percent of this year's survey respondents agree, citing a solution that provides real-time detection, analysis and mitigation of sophisticated attacks as the best choice for cyber protection. The detection and remediation of APTs emerged as a top criterion for such a solution, followed by real-time threat analysis and detection and remediation of bots.


"Each year, the cyber security survey yields results that consistently underscore the importance of real-time detection and analysis of network traffic,�? said Greg Oslan, CEO and president of Narus. “We look forward to working with our customers and partners to help them better manage and protect their networks against the increased volume and sophistication of cyber threats with NarusInsight."
