Updates from Ciena

By John Hawkins – 100G. One hundred billion bits per second. Let that sink in for a minute.

You may have seen broadband offers from your local phone, cable, or wireless operator for 1 Gb/s services. But 100 Gb/s? Nice as it sounds, who needs it? Well, you’d be surprised.

As it turns out, 100GbE service is in demand for several reasons. Not in your residential context, mind you, but in a growing number of enterprise and operator scenarios – and it’s starting to get noticed. Current industry projections estimate that almost $7B (US) worth of 100G Ethernet services will sell this year, and will approach $20B by 2020.

We have been experiencing continued growth in bandwidth consumption for years. No surprise there. Shipments for 1GbE ports are still the sweet spot and the volume leader, while 10GbE ports are gaining ground according to Ovum. The trend is driven primarily by the growth in enterprise/residential service aggregation, mobile network buildouts, and data center interconnect. more>

Optic Zoo Networks Keeps Vancouver’s Data Traveling at Blistering Speeds with Ciena

By Tony Ross – Optic Zoo Networks is a recognized brand throughout metro Vancouver due to our extensive carrier grade dark fiber network and infrastructure. Based on demand and to further accelerate our growth and better serve Tier 1 service providers, we knew it was time to take our offerings to the next level.

Our customers need to support bandwidth-hogging applications like virtual and augmented reality, as well as Internet of Things (IoT). However, in order for data to continue to flow with ease, we needed to ensure that Optic Zoo Networks was ready to support that growth. That meant offering new Carrier Ethernet Services (CES), and in turn, required that we build a Carrier Ethernet Network (CEN).

To continue to support top-echelon service providers, however, we needed to build a CEN that could scale instantaneously and meet the needs of organizations in a range of industries – from finance, healthcare, education, and more.

For example, customers that previously wanted to upgrade to higher levels of bandwidth had to go through inefficient processes, such as having to order a network loop that could take weeks. With our CEN, today’s 1G customers can easily upgrade to 10G tomorrow with a simple software upgrade. more> https://goo.gl/fh54t3

#Ciena25: The Story Behind the Founding of Ciena

By Bruce Watson – The company that would eventually become Ciena began its life as an inspiration inside the head of David Huber.  The former General Instruments engineer had an idea for how to help cable companies squeeze more television channels through their lines to end consumers.  In 1992, he set out to turn those ideas into a reality, and on November 8, 1992, the paperwork was officially filed in Delaware for the new company.

Huber immediately began searching for venture capital funding.  In late 1993, Huber was introduced to Pat Nettles, a veteran leader of several telecom companies.  By early 1994, Nettles was brought on-board to run the business side of things and was soon the company’s first CEO (though owning a doctorate in particle physics, Nettles was no stranger to the technology side of things himself).

Nettles quickly convinced Huber that it was the long-distance phone companies, not the cable TV industry, that would be the best target for Huber’s invention.

The introduction between the two was orchestrated by Jon Bayless, a venture capitalist who’s firm Sevin Rosen Funds provided $3 million in start-up funding for the business in February 1994. more> https://goo.gl/ZdVzLE

Coherent optical turns 5

Ciena's 40G WaveLogic 2 line card, 2008 (Ciena)By Bo Gowan – To fully appreciate the impact that coherent optical technology has had on the telecom industry, you need to understand the barriers that optical vendors ran into as they looked to develop the next step in transport past 10G ‘e2’80ldblquote and that story begins back in the go-go dot.com days of the late 1990s.par
par
A team of engineers at Nortel had spent many weeks putting the finishing touches on a new optical transport demo unveiled on the company’e2’80’99s booth at Telecom 99.’c2~ The demo was an industry-first ‘e2’80ldblquote transmitting 80 Gbps of data over a single wavelength of light across a span of 480 kilometers from Geneva to Paris ‘e2’80ldblquote and it caught the attention of the entire industry.par
par
In 2001, the huge optical boom came to a crashing end. Network operators had drastically overbuilt global fiber capacity during the dot.com bubble, and it would be years before spending on optical transport equipment would fully rebound. The demands coming from network operators changed in an instant for optical equipment vendors.par
par
With new network builds no longer on the horizon, Dino DiPerna and his team knew that a completely new direction was needed.par
par
What the team produced was not so much of a single change in optical transmission but an entire series of new optical transport concepts and inventions that together enabled what we know today as coherent optical transport.par
par
‘e2’80’9cThat first chip was the birth of what we now call WaveLogic, it was the first generation of DSP-assisted electro-optics,’e2’80’9d said DiPerna. ‘e2’80’9cTransmit digital compensation allowed the use of a traditional receiver design without the need for the customer to worry about dispersion. We knew we were on a path that represented the future of optical transport.’e2’80’9dpar
par
But to achieve coherent 40G required a revolutionary set of new technologies and innovations that could all fit together in perfect compliment.par
par
‘e2’80’9cThat 40G coherent project was a great example of a diverse team coming together to solve a problem from all angles,’e2’80’9d said DiPerna. ‘e2’80’9cIndividually, each technology advancement was impressive ‘e2’80ldblquote whether it be the advanced DSP, the coherent receiver using DP QPSK, the analog-to-digital converter development, or a dozen other parts to the puzzle.’e2’80’9d more> http://tinyurl.com/bleymmcpar

Made in IBM Labs

IBM – IBM (NYSE: IBM) scientists developed a prototype optical chipset, dubbed “Holey Optochip”, that is the first parallel optical transceiver to transfer one trillion bits – one terabit – of information per second, the equivalent of downloading 500 high definition movies.

With the ability to move information at blazing speeds – eight times faster than parallel optical components available today – the breakthrough could transform how data is accessed, shared and used for a new era of communications, computing and entertainment. The raw speed of one transceiver is equivalent to the bandwidth consumed by 100,000 users at today’s typical 10 Mb/s high-speed internet access.

“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.”

Using a novel approach, scientists in IBM labs developed the Holey Optochip by fabricating 48 holes through a standard silicon CMOS chip. The holes 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. more> http://is.gd/KXDPxY
