The Open ROADM MSA adds new capabilities in Release 2.0

The Multi-Source Agreement (MSA) for open reconfigurable add-drop multiplexers (ROADM) group expects to publish its second release in the coming months. The latest MSA specifications extend optical reach by including line amplification and adds support for flexible grid and lower-speed tributaries with OTN switching.

Xavier PougnardThe Open ROADM MSA, set up by AT&T, Ciena, Fujitsu and Nokia, is promoting interoperability between vendors’ ROADMs by specifying open interfaces for their control using software-defined networking (SDN) technology. Now, one year on, the MSA has 10 members, equally split between operators and systems vendors.

Orange joined the Open ROADM MSA last July and says it shares AT&T’s view that optical networks lack openness given the proprietary features of the vendors’ systems.

TIP seeks to shake up the telecom marketplace 

The telecom industry has long recognised the benefits of the Internet content providers' data-centre work practices. It has led to the operators starting to embrace software-defined networking (SDN) and network function virtualisation (NFV) technology whereby telecom functions that previously required custom hardware are executed as software on servers.

 Niall Robinson

Now, ten telcos, systems vendors, component and other players have joined Facebook as part of the Telecom Infra Project, or TIP, to bring the benefits of open-source design and white-box platforms to telecoms. TIP has over 300 members and has seven ongoing projects across three network segments of focus: access, backhaul, and core and management.

NeoPhotonics samples its first CFP-DCO products

NeoPhotonics has entered the fray as a supplier of long-distance CFP pluggable modules that integrate the coherent DSP-ASIC chip with the optics. 

The company has announced two such CFP Digital Coherent Optics (CFP-DCO) modules: a 100 gigabit-per-second (Gbps) module and a dual-rate 100Gbps and 200Gbps one.

“Our rationale [for entering the CFP-DCO market] is we have all the optical components and the [merchant coherent] DSPs are now becoming available,” says Ferris Lipscomb (pictured), vice president of marketing at NeoPhotonics. “It is possible to make this product without developing your own custom DSP, with all the expense that entails.”

Infinera unveils first platforms using its latest PIC & DSP  

  • The Cloud Xpress 2 platform for data centre interconnects packs 1.2 terabits in a 1 rack unit (1RU) box.  
  • Infinera has also unveiled two DTN-X XT 'meshponder' platforms that aggregate client signals and offer sliceable transponder functionality that delivers wavelengths to multiple destinations. 
  • The company also announced an open flexible grid line system that supports the C and L bands 
  • Three of the top four US internet content providers are Infinera customers.

Infinera has started to unveil its platform portfolio based on its Infinite Capacity Engine that combines the company's latest-generation photonic integrated circuit (PIC) and coherent DSP-ASIC technology.

The first platform using the technology is the Cloud Xpress 2, Infinera second-generation data centre interconnect platform, was unveiled in September. More recently, it has added two DTN-X meshponder platforms - the XT-3300 and the XT-3600 - as well as upgrading two of its existing DTN-X platforms.
