Ciena unveils WaveLogic 5: 800G and so much more
By Scott McFeely – Today is an exciting day at Ciena, as we have unveiled the next generation of our WaveLogic coherent technology – WaveLogic 5. Introducing the next member of our WaveLogic family is not something we take lightly, because as my friend and colleague Dino Diperna says, “If we aren’t pushing technology to the boundaries, then we’re not delivering the optimal solution for our customers.”
So it’s not surprising that Ciena is once again raising the bar in coherent optical technology by providing the scale, flexibility and intelligence that solidifies our position as a leader in optical networking and your trusted partner for building the Adaptive NetworkTM. And we aren’t just coasting on our past successes. With WaveLogic 5 we are introducing two new solutions that can deliver coherent technology however our customers need it – from integrated systems to pluggable form factors – addressing the complete set of technical and economic requirements they have across a range of network applications.
There is a lot to unpack in today’s announcement, so let’s start by addressing the 800-pound gorilla in the room…do network operators really need 800G?
The answer is a resounding YES.
Our customers are responsible for providing the foundation of society’s digital lifestyle, and that requires moving massive amounts of data around the world – at the speed of light. While these challenges are not new, they are becoming more acutely felt. The pressure to deliver new revenue opportunities while cost-effectively supporting increased traffic demands is forcing providers to evolve and transform their optical networks. more>

Earth observation for weather prediction – solving the interference problem
By ITU News – “Today, several dozen satellites contribute to the accumulation of critical knowledge about the Earth’s system, enabling scientists to describe specific links between a major natural disturbance in the upper atmosphere, and changes in the weather thousands of miles away,” says Mario Maniewicz, Director of the ITU Radiocommunication Bureau.
“As accurate weather predictions need to start from the best possible estimate of the current state of the atmosphere, it is crucial that meteorologists have real-time, accurate global observations about what is happening in the Earth’s atmosphere over land and oceans. And for this, they rely on space sensing.”
Space sensing relies on the deployment of sensors to obtain data critical for Earth observation from space. Active sensors are radar systems on spaceborne platforms. They obtain data through the transmission and reception of radiowaves. Passive sensors, meanwhile, are very sensitive receivers that measure the electromagnetic energy emitted and scattered by the Earth, and the chemical constituents in the Earth’s atmosphere. They require protection from radio-frequency interference.
Spaceborne sensors measure the background natural radiative emission floor, therefore any man-made signal (e.g. communications, radars) that rises above this natural emission floor will likely interfere with the measurements. This interference can be tolerated only if its energy is well below the sensor sensitivity. more>

Pluggables: Their role in coherent technology evolution
By Patricia Bower – In the optical networking industry, pluggable client optical modules are a dominant trend for very short links within buildings and campus networks. Market economics that have driven the proliferation of these pluggables include factors such as simplicity, interoperability and volume-driven cost. And in the domain of short-reach (sub-10km), point-to-point fiber optic connections, the advantages listed above for using small form-factor, pluggable modules shine through.
This is particularly so in the case where transport of high-speed Ethernet client signals is the primary requirement. Connectivity within and between data centers has grown at a very rapid rate over the last few years, both from the perspective of transmission speed and number of connections. The use of optical signaling to transport these high-speed Ethernet signals has proven to be very efficient.
The optical networking industry has a well-established and large ecosystem of vendors bringing small form-factor client modules to market. Many of these are supported by MSAs (Multi-Source Agreements) which can be one of two types; those that define optical transmission specifications and those that define mechanical forms.
More recently, the data rates supported by pluggable form factors have increased. The 100G Lambda MSA group, of which Ciena is a member, has exhibited live demonstrations of interoperable Ethernet modules from member companies. The 100G Lambda MSA specifies 100Gb/s over 2km and 10km of single-mode fiber (SMF), and 400 Gb/s links over 2km of SMF. These modules will be based on the use of PAM-4 coding to get to a data rate of 100Gbps per wavelength. more>

The implications behind service and content provider requirements for coherent optical solutions
By Helen Xenos – In 2007, I was asked to write a white paper about this really cool new “coherent technology” our team was working on and explain how the coherent receiver would completely revolutionize optical networks as we knew them. As I tried to get started, I quickly learned that the only source for content were the engineers actually working on the project – my efforts of scrolling through pages upon Google search pages netted zero information.
The evolving coherent optical networking landscape: a deep dive
In the end, I wrote the paper by transcribing what a dear co-worker and mentor, Michel Belanger, who was one of the designers, patiently explained to me (it took several hours). He made sure I understood the significance of coherent technology and how it would change the game in optical networks.
Fast forward a dozen years – there is no shortage of information pertaining to coherent technology, and there are about a dozen coherent module and system suppliers. Coherent optical systems have become the networking foundation that underpins the digital economy that we know today.
Network providers are ubiquitously deploying coherent to scale networks for capacity, reduce transport costs and provide a better end-user experience to their customers. In fact, they are now looking at expanding the role that coherent technology plays in the network and deploy it in space and power/optimized applications in addition to traditional infrastructure, submarine and data center interconnect (DCI) build-outs.
As coherent technology plays an increasingly critical role for successful network evolution, we must step back and ask ourselves:
- What do network providers need from their coherent solution partners to succeed?
- What are the implications of the divergent customer and networking requirements to the suppliers of the technology?

4 critical requirements for the next-gen photonic layer
By Paulina Gomez – Today’s market dynamics are making it harder for network providers to effectively compete in an environment where revenue per bit is declining, and network bandwidth requirements are exploding. In the face of these business challenges, network providers are realizing they must evolve and transform their networks towards a more programmable infrastructure that can scale and respond on demand, to meet changing customer expectations and unpredictable traffic requirements.
While coherent optics are a critical element in enabling a programmable optical infrastructure, alone they are not enough to fulfill operators’ requirements for successful network transformation.
So what else is needed?
The photonic layer is the foundation of this programmable infrastructure, leveraging the latest coherent optical technology to deliver maximum scale at the lowest cost per bit. When examining the requirements of metro and long-haul infrastructure applications, including global data center interconnect (DCI) networks, there is a growing need for an agile, resilient and intelligent photonic layer.
This Reconfigurable Add-Drop Multiplexer (ROADM)-based optical foundation leverages flexible, instrumented photonics and Layer 0 software control to scale the network for maximum capacity at the lowest space, power, and cost per bit. more>
