Actelis Supplies EFM to Harzwasserwerke GmbH

Harzwasserwerke GmbH has selected Actelis Networks' high-performance Ethernet in the First Mile (EFM) solutions to replace legacy Plesiochronous Digital Hierarchy (PDH) and outdated E1 technology. The water utility has deployed Actelis’ ML600s Ethernet Access Devices (EADs), which deliver high-speed broadband services over the company’s existing copper and fiber networks. The compact, cost-effective EADs deliver up to 100Mbps of symmetrical bandwidth over the existing copper network.


Harzwasserwerke is one of the largest suppliers of water in Germany, delivering about90 billion litres of water annually over a system of more than 500km of pipeline. The distribution system consists of several substations and sophisticated sensors that are constantly monitoring the pipeline and communication with a centralized data center.


Partnering with Actelis on the project, 3M Services GmbH is responsible for delivering a complete end-to-end network solution.http://

Ciena Posts Revenue of $416.7M, Net Loss of $48M

Ciena reported revenue of $416.7 million for its fiscal first quarter 2012. Net loss for the fiscal first quarter 2012 was $(47.7) million, or $(0.49) per common share, which compares to a GAAP net loss of $(79.1) million, or $(0.84) per common share, for the fiscal first quarter 2011.


"Our first quarter revenue reflects the combined effects of seasonality and longer customer deployment and revenue recognition cycles as a result of our greater mix of international and solutions-oriented sales," said Gary Smith, president and CEO of Ciena. "However, our first quarter revenue does not reflect the underlying strength of the business and ongoing customer demand. We expect sequential revenue growth in the fiscal second quarter, and we anticipate that our operating results for the second half of fiscal 2012 will be stronger than the first half."http://

IBM Labs Develops "Holey" CMOS Optochip Hits Terabit Rates

Researchers at IBM Labs have achieved terabit data transfer speeds by fabricating tiny holes in a single quarter-inch parallel optochip. Potential applications include ultra-high interconnect bandwidth to power future supercomputer and data center applications.


The prototype optical chipset, dubbed "Holey Optochip", is the first parallel optical transceiver to hit the terabit mark.


"Reaching the one trillion bit per second mark with the Holey Optochip marks IBM's latest milestone to develop chip-scale transceivers that can handle the volume of traffic in the era of big data," said IBM Researcher Clint Schow, part of the team that built the prototype. "We have been actively pursuing higher levels of integration, power efficiency and performance for all the optical components through packaging and circuit innovations. We aim to improve on the technology for commercialization in the next decade with the collaboration of manufacturing partners."


According to IBM, the 48 holes which were fabricated through a standard silicon CMOS chip, allow optical access through the back of the chip to 24 receiver and 24 transmitter channels to produce an ultra-compact, high-performing and power-efficient optical module capable of record setting data transfer rates. The Holey Optochip achieves record speed at a power efficiency (the amount of power required to transmit a bit of information) that is among the best ever reported. The transceiver consumes less than five watts; the power consumed by a 100W light bulb could power 20 transceivers. This progress in power efficient interconnects is necessary to allow companies who adopt high-performance computing to manage their energy load while performing powerful applications such as analytics, data modeling and forecasting.


Specifically, a single 90-nanometer IBM CMOS transceiver IC with 24 receiver and 24 transmitter circuits becomes a Holey Optochip with the fabrication of forty-eight through-silicon holes, or "optical vias" – one for each transmitter and receiver channel. Twenty-four channel, industry-standard 850-nm VCSEL (vertical cavity surface emitting laser) and photodiode arrays are directly flip-chip soldered to the Optochip.

NTT Announces 10 Gbps Optical Amplification with 100km Reach

Nippon Telegraph and Telephone Corporation (NTT) announced a new optical amplification technology capable of delivering 10 Gbps at 100km reach. The technology was developed in collaboration with Japan's National Institute of Information and Communications Technology.


NTT Access Network Service Systems Laboratories said the new optical amplification technology provides inexpensive wide dynamic range optical amplifiers and can handle burst signals generated in Ethernet PON systems. The optical amplification technology includes an automatic level control (ALC) technology that can assess the input burst signals and, at high speed, adjust them to a constant level by controlling optical attenuators.


In a field trial carried out in Hokkaido prefecture, NTT East buildings in Sapporo, Toyohira, Eniwa and Chitose were connected by optical fibers with total length over 100km. Good results were reported.

Apple's New iPad Packs LTE

In what could be a major inflection point for adoption of LTE, Apple confirmed that its new iPad will offer LTE. In the United States, both AT&T and Verizon are offering LTE iPad connectivity, however the user must choose at the time of purchase as the devices are configured for each carrier's network.


Significantly, iPad users will be able to sign-up and leave the service on a monthly basis -- no long term contract. The new iPad also tracks your monthly data usage and alerts you to a coming threshold.


If the carrier supports it, the iPad can now be used as a personal Wi-Fi hotspot to connect up to five devices.


Among its other upgraded features, the new iPad also records in full 1080p. The huge video files will be uploaded via iCloud for offline storage and/or transfer to other devices.


iPad Wi-Fi + 4G for either AT&T or Verizon will be available for a suggested retail price of $629 (US) for the 16GB model, $729 (US) for the 32GB model and $829 (US) for the 64GB model.
