Cost-Effective Short Wavelength Division Multiplexing (SWDM)

Applications Presently Using SWDM

Factoring that fiber infrastructure costs, parallel multimode MPO cabling is largely more costly than LC-duplex fiber patch cords. For direct port-to-port connections, it’s more desirable to use a single fiber pair instead of MPO trunk to keep costs down.

For supporting smooth migration from 10G to 40G Ethernet, Cisco released a proprietary 40G bi-directional (BiDi) transceiver solution that allows reuse of the duplex multimode fiber pair for 40G connection. The BiDi transceiver utilizes two wavelengths (850nm and 900nm) transmitting in the same fiber on opposite directions, with an actual bit rate of 20 Gbps. It supports 40G data transmission up to 150m in OM4 multimode fiber.

Arista’s 40G universal transceiver is another solution that supports LC-duplex fiber pair instead of MPO. The 40GBASE-UNIV supports a reach of 500m singlemode fiber and 150m reach in OM4. Similar solutions are also available from Juniper (40G-LX4) and Finisar (40G-LM4).

In short-reach datacom applications, BiDi and Universal transceiver solutions have proven to be market successes.

New SWDM Applications in WBMMF

Historically, compared to singlemode transceivers, multimode transceivers cost less and are more efficient in power consumption. The introduction of wideband multimode fiber will maintain the appeal of multimode fiber cabling systems for next-generation Ethernet speed implementation with SWDM technology.

Since 40G Ethernet was introduced, QSFP has become the most popular form factor for 40G and 100G Ethernet physical interfaces. Recently, new SWDM-based QSFP multimode transceivers, including 40G-SWDM4, 100G-SWDM4 and 100G-SWDM2, have been demonstrated by a few vendors.

In regard to standardization, the SWDM4 consortium built a consensus that 4-wavelength is a viable solution, and it’s possible to support up to eight wavelengths in the single MMF. In the IEEE 802.3 working group, WBMMF was already taken into consideration for new standards development.

If you opt for SWDM transceivers in your next data center deployment, we recommend taking a close look at OM5 to support desired reach and link performance.

What is Layer 0?

Beneath your IT infrastructure lies a foundation: layer 0. It’s the one we often don’t talk about. It’s constantly overlooked but is so critical. Installed behind walls and above the ceiling, behind closed doors and in dark rooms, your cabling – although hidden, and seldom the topic of conversation among IT professionals – is, in my opinion, the most important layer of your information communication technology (ICT) infrastructure.

What is Layer 0?

Basically, layer 0 is made up of your infrastructure cabling and connectivity. It allows data to be reliably transmitted from one place to another at high speeds – whether users/devices are in the same room, in different buildings or separated by thousands of kilometers.

Making Ethernet a Viable Option to Control Stage Lighting

Imagine what it would be like attending a concert or a live theater performance without a coordinated light show. How would that impact the experience? With the amazing effects that can be achieved thanks to advancements in lighting over the past decade, it would not be nearly the same.

Years ago, most lighting systems communicated using proprietary serial protocols. This made interoperability between different OEM’s equipment problematic and often impossible. To rectify this situation, the lighting industry got together and agreed that one common standard digital protocol must be created.

The Road to Standardization in Theater and Stage Lighting – DMX512 & DM512-A

DMX512 is a standard for digital communication networks commonly used to control stage lighting and effects; it was originally intended as a standardized method for controlling light dimmers. Developed by the United States Institute for Theatre Technology (USITT) Engineering Commission, the DMX512 standard (for “digital multiplex with 512 pieces of information”) was created in 1986, with subsequent revisions in 1990 leading to USITT DMX512/1990.

DMX512-A – In 1998, the Entertainment Services and Technology Association (ESTA) began a revision process to develop DMX512 as an ANSI standard. The resulting revised standard, known officially as “Entertainment Technology – USITT DMX512-A – Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories,” was approved by the American National Standards Institute (ANSI) in November 2004. It was revised again in 2008, and is the current standard known today as “E1.11 – 2008, USITT DMX512-A” (or just “DMX512-A”).

Ethernet is expanding as a means to communicate control signals that vary the intensity, color, timing and position of elements in theater and stage lighting systems. 

The ways that Ethernet can support theater and stage lighting

Flexible Data Centres Are Like Lego Blocks

Standardization can assist your data centre deliver constant high-quality performance on time and in a safe environment. In the world of data centres, “standardization” means that processes follow the same steps, in the same sequence, while using a set of products and systems with predefined characteristics. If data centres lack standardization, then “improvisation” (executing a task without preparing or knowing what’s ahead) often takes over. This eats up valuable time, leads to mistakes caused by human error and produces inconsistent results and unexpected delays.

While the word “standardization” seems restrictive, it actually can lead to the opposite: flexible data centers that make the most of capital investments, improve space utilization and prevent unplanned downtime. Which is more important: standardized or flexible data centers? Or can you have both? It’s vital to standardize where you can – but it shouldn’t come at the loss of flexibility to meet your unique (and changing) goals.

When combined appropriately, standardized, flexible data centers offer numerous benefits. Because it can be hard to describe, we’re going to use Lego blocks as an example. While Lego blocks are standardized, they also provide a world of flexibility:

  1. The Ability to Scale Quickly
  2. Easy “Maintenance”
  3. Ramp Up Easily for Fast Deployment
  4. Pieces Designed to Work Together

An Elephant in the Industrial Control Room?

There is an elephant in industrial infrastructure control room. Most of the equipment within the US infrastructure sectors is at risk of aging out, currently requiring replacement and upgrades, yet still in production use.

Which means industrial networks, endpoints, control systems and other types of specialized systems and production equipment across many industries are in drastic need of replacement or upgrade.  For water and wastewater treatment facilities, the useful life of system components is estimated to be 15-95 years old according to the American Society of Civil Engineers (ASCE) and their report “Failure to Act – The Economic Impact of Current Investment Trends in Water and Wastewater Treatment Infrastructure”

Many of the components were installed in the 1950s for most major cities, years before today’s modern networks, technical advances, application architecture, industrial protocols, cyber security risks, compliance requirements, safety regulations and other factors applied.

Subsequently, It was no surprise when, in 2012, a large, growing California metropolis proposed funding for a new power generation and water treatment plant to increase capacity and replace its aging infrastructure

F1 Racing Details a Real-Life Example of the IIoT

During an F1 race sensors in the car constantly communicate with the track, the pit crew, a team of engineers and the onsite broadcast crew. The immense volume of real-time data is put into predictive intelligence models and used for race strategy and car servicing. Data analysis and two-way communication happen simultaneously to create a competitive edge that can turn a losing car into a winner.

In many ways, the factory floor or industrial facility is like an F1 race car. Hundreds of sensors and machines generate more and more data. If you could input this data to the right decision-makers in a timely and easily decipherable way, how could your business be transformed? Could you improve reliability, efficiency, safety and production?

Some F1 teams are already transferring their knowledge to other industries. For example, Conoco Philips is testing this approach on oil rigs with assistance from the British automaker McLaren.

Five Ways to Move Forward on the IIoT

The Industrial Internet of Things (IIoT) enables the connectivity that allows businesses to gather greater insights and make data-driven decisions to achieve greater results. Though we don’t know all the applications that our businesses will build on the IIoT, there are two things we do know for certain:

  • More and more devices will connect to our industrial networks.
