Nistica unveils FLEXBOX grid-flexible, disaggregated ROADM

Nistica, a Fujikura subsidiary and supplier agile optical networking solutions, has unveiled FLEXBOX, a disaggregated ROADM node designed for next-generation software defined networks (SDN), and plans to work with existing system vendor customers to deliver the product to carriers and webscale end customers.

Offered in single rack unit (1 RU) form-factors, Nistica's products are designed to enable broadcast-and-select and route-and-select architectures by integrating its grid-flexible single and dual C-band and L-band wavelength selective switches (WSS).

For the new solution, Nistica has leveraged gain-controlled optical amplification derived from its expertise in ROADM blade optical signal control loops that is incorporated with the WSS technology to enable an automated optical layer for carriers seeking hands-free operation via software control.

Nistica is introducing a customised black-box model whereby OEMs can specify optical layer differentiators, as well as tailor the software layer to offer advanced optical capabilities to end customers. Based on standardised SDN support of NetConf and RestConf network management interfaces through Yang models, FLEXBOX is designed to be compatible with emerging standards within collaborative platforms such as OpenROADM and Telecom Infrastructure Project (TIP).

Nistica is demonstrating the functionality of the FLEXBOX solution at OFC 2017 in Los Angeles.

AT&T Activates First Open ROADMs with Ciena and Fujitsu

AT&T recently activated a 100 Gbps wavelength in its production network in the Dallas area that uses Open ROADM-compliant technology. Specifically, AT&T connected 2 high capacity IP/MPLS routers with transponders and ROADMs provided by Ciena and Fujitsu.

Open ROADM project is a project underway with the backing of AT&T and a goal of driving faster innovation and open software control for the Reconfigurable Optical Add/Drop Multiplexers (ROADMs) used in optical transport networks. An Open ROADM Multi-Source Agreement (MSA) defines interoperability specifications for Reconfigurable Optical Add/Drop Multiplexers (ROADM). Included are the ROADM switch as well as transponders and pluggable optics. Specifications consist of both Optical interoperability as well as YANG data models.

In a blog posting, Andre Fuetsch, President of AT&T Labs and CTO, said the newly installed ROADMs support full software control according to the published Open ROADM specification. NetConf/YANG APIs are used for controlling and managing the optical network. The 100G wavelength was provisioned using an SDN ROADM Controller developed by Fujitsu and integrated into the AT&T ECOMP architecture.

Infinera Validates Optical Line Systems with Lumentum's White Box

Infinera and Lumentum have validated Infinera’s portfolio of DWDM platforms over Lumentum’s white box optical line system.

The interoperability testing included Infinera’s XTM Series, Cloud Xpress Family and DTN-X Family (including XTC and XT Series) platforms. In addition, the companies successfully conducted interoperability testing of Infinera’s next generation Infinite Capacity Engine pilot hardware.

Specifically, the Infinera platforms interoperated with the Lumentum white box open line system including the 20 port Transport ROADM. The test cases covered point-to-point metro fiber links carrying multiple modulations including QPSK (quadrature phase shift keying), 8QAM (quadrature amplitude modulation) and 16QAM with PIC based super-channels over the Lumentum open line system. The test was able to fill the fiber to full capacity at QPSK, 8QAM and 16QAM data rates via 19 super-channels injected into a single rack unit 20 port ROADM. A fully loaded solution achieves up to 24 terabits of fiber capacity using the Infinite Capacity Engine at 16QAM. The testing successfully validated standard optical parameters including optical signal to noise ratio (OSNR) for seamless performance over metro distances.

The companies described the interoperability testing as the first multi-vendor driven demonstration of, and commitment to supporting, an open, interoperable and agile approach to the construction of transport networks, including for data center interconnect (DCI) and metro/edge WDM transport.

Infinera and Lumentum also noted that they are collaborating on open packet optical transport in the Telecom Infra Project (TIP), an industry initiative co-founded by Facebook.

“By validating the industry’s first white box open line system interoperability with Lumentum, Infinera has demonstrated our commitment to delivering the innovative and open optical solutions that our customers need,” said Tom Fallon, Infinera CEO. “Infinera’s leadership in technology innovation with large-scale photonic integration is changing telecom networks. This announcement is yet another step in the path to delivering on our vision of enabling an infinite pool of intelligent bandwidth that the next communications infrastructure is built upon.”

“Lumentum’s award-winning optical white boxes are designed for simplicity and scalability, with open interfaces to enable Software Defined Networking (SDN),” said Alan Lowe, Lumentum CEO. “The demonstration of successful interoperability with Infinera validates the open system approach that should deliver the simplicity and service innovation many network operators desire.”

Infonetics: WDM ROADM Sales Rose 10% Last Year

The global WDM ROADM equipment market (not components) reached $4 billion in 2012, up 10% year-over-year, according to a new report from Infonetics that tracks the reconfigurable optical add/drop multiplexer (ROADM) optical network equipment market and the wavelength selective switch (WSS) components within it, measured by spacing technology and degree count.

Some highlights of the report:

  • ROADM WSS component revenue declined more than a quarter in 2012
  • In the 2nd half of 2012, sales of ROADM WSS components stabilized while recording healthy unit growth
  • The leading vendors in the WDM ROADM optical hardware market in 2012 include Alcatel-Lucent, Huawei, Ciena, and Fujitsu.

"It’s been a tough road for WSS components these past couple of years, with quarterly revenue down nearly 50% from the highs two years ago," notes Andrew Schmitt, principal analyst for optical at Infonetics Research. “But we believe there’s some modest growth ahead tied to the deployment of new 100G coherent systems and the rollout of colorless, directionless and contentionless (CDC) ROADMs. While the level of interest in CDC ROADMs is very high from vendors, the current pricing premium given to this architecture by equipment vendors will slow adoption."

ADTRAN Adds Four-Degree ROADM

ADTRAN introduced a new four-degree, scalable, compact Reconfigurable Optical Add/Drop Multiplexer (mini-ROADM) system-on-a-blade enables greater flexibility for service providers to respond to shifts in traffic and capacity demands in their residential, business, wholesale and mobile backhaul networks. ADTRAN's Optical Networking Edge (ONE) blade solution integrates into its flagship Total Access 5000/5006 platform.

ADTRAN said the flexibility of the four-degree, gridless mini-ROADM design reduces complexity in the network compared to alternative ROADM architectures that typically require a multi-blade implementation and a separate service delivery platform. The mini-ROADM design also simplifies agile optical network deployments by uniquely integrating into a single card the typical distributed and over-sized ROADM sub-elements, such as the amplifiers required to adjust for optical losses. These new features allow service providers to rapidly respond to customer requirements in dynamic markets like residential broadband, carrier Ethernet and 4G backhaul.

In addition, ADTRAN has doubled the transmission capacity of its ONE portfolio for up to 88 wavelengths of 10 Gbps. Future upgrade to 100Gbps networking and services will also be supported.

"ADTRAN has been working closely with customers to deliver a solution that allows them to merge multi-service access, aggregation and packet optical transport for increased network flexibility and scalability,” said Mano Nachum, packet optical networking product line manager, ADTRAN’s Carrier Networks Division. "The new ONE capabilities allow service providers to take full advantage of the benefits of agile photonics in response to the ever growing traffic and capacity demands on their metro, middle-mile and access edge networks."
