Mitsubishi Electric Develops 1Tbps Multi-subcarrier Optical Transceiver

Mitsubishi Electric Corporation has developed a multi-carrier optical transceiver capable of one Terabit per second (1 Tbps) rates -- a 10-fold improvement over current mainstream commercial transceivers, which operate at up to 100 Gbs) per optical receiver.

Mitsubishi Electric said it achieved the 1Tbps transmission rate with existing optical fibers by using a multi-subcarrier technology that transmits 11 light waves (subcarriers) simultaneously in a single channel by using an optical comb, a device that creates a series of discrete, synchronized optical waves equally and densely spaced in the channel. While conventional methods would require 11 receivers for the same number of subcarriers, this new technology only requires a single receiver due to the use of densely spaced, synchronized subcarriers in a single channel and novel multi-subcarrier signal processing algorithms. No major changes are required to the existing optical network infrastructure, keeping the cost of deploying this new technology quite low.

Usually, when using subcarriers for optical communication, each subcarrier undergoes different signal distortions, which results in damaged data like video distortion on the receiving end. To avoid this problem, Mitsubishi Electric used pilot signals to accurately realign the subcarriers at the receiver. Known pilot symbols are periodically inserted into the transmitted signal, which serves as a landmark for correct orientation of all subcarriers and prevents data damage.

The experiment also achieved a spectral efficiency of 9.2b/s/Hz, which as of January 2016, was the highest in the world in a 1Tbps transmission using a single optical receiver.

IBM Positions Latest Mainframe for Encrypted Hybrid Clouds

IBM unveiled a new mainframe is enabled and optimized for hybrid cloud environments for mid-sized organizations.

Some highlights of the new system:

  • Security embedded into hardware – The new z13s has advanced cryptography features built into the hardware that allow it to encrypt and decrypt data twice as fast as previous generations, protecting information without compromising performance.
  • Intelligent security capabilities – IBM is integrating mainframe technology with IBM Security software solutions to create a more secure foundation for a hybrid cloud infrastructure. IBM also is offering a new Cyber Security Analytics service to z Systems customers that can help identify malicious activity by learning user behavior over time.
  • Expanded partner ecosystem – IBM is working with leaders in the cyber security industry through the "Ready for IBM Security Intelligence" partner program to help deliver enterprise-wide solutions and offerings tailored to specific client needs. The new partners for z Systems are BlackRidge Technology, Forcepoint (a joint venture of Raytheon and Vista Equity Partners) and RSM Partners.
IBM estimates that he typical enterprise can face an average of 81 million security incidents annually. The z13s includes an updated cryptographic and tamper-resistant hardware-accelerated cryptographic coprocessor cards with faster processors and more memory, providing encryption at twice the speed as previous mid-range systems. A new z Systems Cyber Security Analytics offering delivers an advanced level of threat monitoring based on behavior analytics. The solution, being developed by IBM Research, learns user behaviors and is then able to detect anomalous patterns on the platform, alerting administrators to potential malicious activity.

"Fast and secure transaction processing is core to the IBM mainframe, helping clients grow their digital business in a hybrid cloud environment," said Tom Rosamilia, senior vice president, IBM Systems. "With the new IBM z13s, clients no longer have to choose between security and performance. This speed of secure transactions, coupled with new analytics technology helping to detect malicious activity and integrated IBM Security offerings, will help mid-sized clients grow their organization with peace of mind."

Amdocs: VoLTE Call Drops Are 4-5 Times Higher Than 2G/3G

VoLTE call drops can be four to five times higher than calls on 2G or 3G networks, according to newly published research from Amdocs that analyzed more than 25 million voice and data connections from 80 different network operators around the world in the past 12 months.

"The Amdocs State of the RAN research reinforces the sheer strain mobile networks are under,” said Ann Hatchell, head of network marketing at Amdocs.

Some highlights:

  • VoLTE call drops can be four to five times higher than calls on 2G or 3G networks: VoLTE is an important and strategic service for operators as it offers operating expense (OPEX) and capital expense (CAPEX) reductions through the promise of repurposing 2G and 3G services. However, this study suggests that the quality of experience VoLTE provides initially, post-deployment, can be less stable than the traditional voice service it replaces, requiring aggressive tuning by the operator.
  • Network data demand is increasing every year: Research suggests that the volume of mobile data usage is growing across the world at approximately 60 percent year-on-year, particularly with increased demand for video on devices providing better entertainment opportunities to mobile users. However, with only 5 to 15 per cent of Wi-Fi traffic going through mobile devices that is able to be accurately described as Wi-Fi offload, the study highlights that service providers need to offload more traffic from cellular networks to Wi-Fi networks, in order to realize greater cost and operational efficiencies.
  • Seventy-five percent of network traffic in cities is in-building: In times of network congestion, indoor users face up to a 25 percent increase in network issues compared to outdoors users. By understanding and visualizing the real-world patterns of demand, coverage and congestion, operators could effectively target network optimization efforts at these problem areas to deliver a consistent, quality of network experience.
  • Music and sport events create their own mobile ecosystems: SMS is still the killer app with an average of 70 percent of attendees at a concert or sporting event sending at least one text message during it, which causes spikes in network usage. Therefore, there is a need to manage network capacity during an event, with network cells around an event’s location carrying approximately 50 percent more traffic than the cells inside a stadium for example. This indicates there is considerable communication with fellow event attendees while going to the venue through email, text and social media. Meanwhile, it was also seen that international roamers upload almost 50 percent more data while at events than non-roamers.
  • International roamers suffer poorer network experience: Despite the fact that international roamers can offer operators greater revenues than a corresponding locally-based subscriber, their network experience can be up to 25 percent worse. There is an opportunity for operators to realize greater monetization of services by isolating profitable international roamers, understanding their distinct usage patterns, and optimizing the network to better target them.
