During the “telecom bubble” era of the late 1990s early 2000s, there were high hopes and speculation that all-optical networks would quickly become prevalent. Many envisioned a relatively simple backbone networks where client signals were Read more »
The Optical Transport Network (OTN) defined in ITU-T G.709 is the default protocol that underpins today’s DWDM packet optical transport networks. Two generations of OTN have already been widely deployed: OTN1.0, which was based on 10G WDM transport; and OTN2.0, which enabled the transition Read more »
The security of communication lines is a top priority of service providers and data center operators. DIGI OTN processors can enable secured and low-latency WDM transport with the industry’s most flexible and comprehensive OTN payload encryption at wire-speed for protocol-agnostic datacenter interconnect Read more »
Transponders and muxponders are important elements in an optical transport network. Transponders are used to enable point-to-point connections over long distances when the client rate matches the optical wavelength. In cases where the client rates Read more »
100G WDM ports in metro networks are growing rapidly, with a 45% CAGR (according to the 2016 IHS Technology Report on 100G+ Coherent Optical Equipment Ports Market Report). As many of the service rates are 10G and below, this drives a need for OTN switching Read more »
An OTN-switched network core, as shown in the following illustration, offers significant advantages to network operators with multiple customers and service types. It allows traffic to be groomed Read more »

In my last post, I wrote about how operators are considering a C-RAN architecture enabled by an OTN-based fronthaul network to deploy costly new spectrum in a way that achieves the
highest capacity and lowest cost.

Ever since 1987, players from the winning Super Bowl team have been asked the question, “You’ve just won the Super Bowl, what are you going to do next?” They respond, “I’m going to Disney World!” This led me to wonder how the U.S. Treasury would answer the same question after the conclusion of the latest AWS-3 auctio
n in which Mobile Network Operators bid almost $45B to secure new licenses – a number that easily surpassed analysts’ estimates of between $10B and $20B.

Mobile operators worldwide are investigating new architectures in the Radio Access Network to increase capacity and reduce costs. The C-RAN architecture is the leading solution to this challenge. With C-RAN, baseband processing is moved out of the cell site and into a central location, which creates a new challenge: how to cost-effectively extend the Common Public Radio Interface (CPRI) to the centralized baseband location – a function the industry has named Fronthaul.

With bandwidth demand growing continuously, optical communications must assume an even more central role in carrier, enterprise, and data center networks alike. Yet merely addressing capacity requirements isn’t enough
to meet the needs of the network manager. Optical technology must become less expensive, less power hungry, more efficient, more flexible, and more economical to deploy. That means innovation in fiber optics – and in the electronics that support optical transmission – is more important than ever.
To explore where this innovation is needed, what it must look like, and when we might see it, Lightwave has created the Lightwave Optical Innovation Summit, which will take place this July 14-16 in Austin, TX.

We’re constantly hearing about the phenomenal growth in big data and the resulting increase in traffic on carrier networks worldwide. For example. this interesting infographic by Qmee captures 60 seconds of online traffic in 2013, and the stats are amazing: 350GB of data uploaded to Facebook, two million Google searches, 204 million emails sent, 278,000 tweets—and a whole lot more—every single minute.
Optical network operators have the tremendous challenge of re-architecting their networks to 100G to keep up with this massive traffic growth and doing so profitably.Read more »

As the optical industry gathers to talk about the future of optical networking at OFC 2014 this week, Acacia Communications and PMC announced a major milestone for the 100G OTN ecosystem.
We’ve achieved successful interoperability between our DIGI 120G OTN Processor and Acacia’s AC100 100G Coherent module, which is important step to show that the ecosystem is ready for the 100G transition.
According to Cisco, big data continues to fuel traffic growth of more than 60% per year in metro networks. As a result, service providers are looking for ways to cost effectively increase optical network capacity. 100G Coherent technology allows transmission of 100Gb/s per lambda over existing fiber plant previously installed for 10G, unlocking a ten-fold increase in fiber capacity and eliminating the need for new fiber.
