Solution Brief
Open ROADM
Introduction
Since the initial deployments in the early 2000s, ROADM networks have
generally consisted of individual sets of tightly coupled, proprietary
hardware and software supplied by a single vendor. Consequently,
devloping the design, functionality and architecture of ROADM networks
has been in the hands of individual vendors rather than as a result of
industry collaboration and mutually agreed standards.
Disadvantages of Proprietary ROADM Architectures for Operators
ROADM networks vary considerably from one vendor to another, so
introducing a new vendor into an existing network requires significant
cost and effort. Network operators become “locked-in” to specific
vendors, which quickly reduces flexibility and interoperability that
competition from additional vendors would have brought to the table.
An additional limiting factor is that service providers are “tied” to their
chosen vendor’s innovation velocity. Promising new technologies may
be introduced only to be “held captive” by propriety systems that lack
the agility or interoperability to benefit from them.
Disadvantages of Proprietary ROADM Architectures for Customers
The widespread vendor lock-in phenomenon has significant
consequences for customers as well as service providers. Because
innovation is inhibited in proprietary networks, customers lose out in
terms of missed opportunities for gains such as higher quality, greater
reliability, higher bandwidth, reduced costs or flexible service offerings.
Other “missed” innovations might speed service activation, improve
responsiveness to outages, or offer subscribers the ability to self-select
and configure their own services.
Multivendor Networks and their Challenges
What might seem like the obvious remedy—multivendor networks—
brings its own operational challenges. Getting closed networks to “talk”
to each other and reliably exchange traffic is inherently tricky and
expensive. End-to-end services must be addressed by the vendor
segment of the network and manually “stitched” together. A patchwork
arrangement of this nature requires multiple vendor-specific
management systems and, all too often, results in “swivel chair”
operations, provisioning and management. What’s needed is a different
strategy focused on open standards and open interfaces, with much less
reliance on closed, proprietary technologies and systems.

Solution Brief Open ROADM
The Open ROADM Project: a Collaborative Initiative
The Open ROADM initiative and Multi-Source Agreement (MSA) brought
together multiple vendors and network operators to solve these issues
and create an agreed approach to building networks that are scalable,
cost-effective and flexible. Fujitsu has been a key contributing member
since the project’s inception. You can find more information at the Open
ROADM project website, openroadm.org.
The Open ROADM MSA defines interoperability specifications for ROADM
networks, including control and management. Through collaboration
and co-creation, the MSA community developed a set of specifications
to enable the industry’s first multivendor optical network
demonstration.
Areas Addressed in Open ROADM MSA 1.2
Release 1.2 of the Open ROADM MSA addressed three key areas:
API specifications for management and control
CD-ROADM specification for how the ROADM components interact
Multi-wave specification for transponders, including mapping and
error control
The following interoperability aspects are also addressed:
Disaggregated core architecture for photonics, transponder, and
pluggable optical modules
Optical interoperability among photonics, transponders and
pluggable optics
Abstraction of network complexity with integrated YANG models at
device, network and service layers
Best of-breed hardware and software solutions
Simplified vendor integration through standardized YANG models
Predefined interface specifications for increased interoperability
Multivendor network solutions
Open ROADM Devices
The Open ROADM MSA does not specify the physical design of Open
ROADM devices, but it does define the following functional design:
A ROADM capable of providing colorless and directionless
add/drop functionality
A transponder capable of mapping a single 100 GbE or OTU4 client
signal into a 100G OTU4 DWDM signal for transport across Open
ROADM infrastructure
Common NETCONF/YANG APIs and single/multiwave optical interfaces
on both transponder and ROADM
Standards-based pluggable optics for the transponder
YANG data model for abstracting the management, control and
provisioning of multivendor ROADM and transponder devices
An Open ROADM controller that controls the ROADM and provides device,
network and service APIs to northbound OSS systems
Open interfaces that define the optical specifications between
ROADMs and transponders to enable interoperability
The Fujitsu Open ROADM Solution
The Fujitsu Open ROADM solution is specifically developed to meet the
standards set forth by the MSA community. The solution brings together
the 1FINITY™ disaggregated optical networking platforms; the Virtuora®
suite of SDN/NFV software tools and applications; and expert
multivendor integration services. The integrated solution was used to
demonstrate the industry’s first Open ROADM multivendor
interoperability in collaboration with another vendor.
1FINITY Hardware
Fujitsu 1FINITY optical networking blades offer an architecturally
flexible, disaggregated design together with APIs and software based
on open-source standards. These platforms seamlessly deploy into an
open environment
For CD ROADM functionality up to four degrees, the 1FINITY L100 Series
blades provide a twin 1 × 9 WSS ROADM-on-a-blade and an optical
muxponder with dual 4 × 16 add/drop plug-in units. The ROADM
interfaces with the 1FINITY T300 Transport blade, a 10 × 100 GbE/OTU4
client transponder optimized for 100G/200G metro applications.
Management is via 1FINITY C201 and C202 Communications Integrator
blades with the Fujitsu Rack Manager software tool, which provides a
single management interface for the multiple blades in an Open
ROADM node. Our open APIs extend management to a third-party
optical Time-Domain Reflectometer (OTDR) supplied by EXFO, Inc.

Virtuora Software
Using Virtuora Network Controller (NC), Fujitsu Open ROADM solutions
support a multivendor environment for service activation, alarm
management, performance monitoring, and topology discovery.
Virtuora NC is an SDN network controller that combines open RESTFUL
APIs with standard NETCONF interfaces, and uses YANG-based data
models to deliver 100G services over the Open ROADM network.
Fujitsu Integration Services
The Fujitsu Integration Services team works as a trusted partner to help
operators meet the challenges of deploying an Open ROADM network.
Our expert project managers and engineers ensure efficient, timely
communication and coordination with vendors, ensure the project is
planned and executed on time, help minimize financial and other risks,
and resolve issues that arise.
Network integration services include:
Consulting
Design and planning
Systems integration

Maintenance and support
Determining the Best Implementation Plan
Network providers can introduce a fully Open ROADM network, or
variations tailored to their network, using the hardware and SDN
controller from the Fujitsu solution. Our approach combines industry
compliance with flexibility to define the level of open solution desired.
By combining the blades needed to meet network requirements,
including equipment from different vendors, and by leveraging the
commonality of the APIs and management functions, it is possible to
realize the operational efficiencies of provisioning across multiple
vendors in an Open ROADM environment.
With the modular disaggregated approach in building networks and the
elimination of vendor lock-in you can implement equipment at least one
generation more advanced than traditional converged deployments.
Conclusion
Service providers need solutions for modular, scalable networks that
offer both freedom of choice and pay-as-you-grow financial flexibility.
These goals can be achieved via the Open ROADM MSA’s vision of an
open architecture and multivendor environment. This environment lets
operators select the best product for their requirements while ensuring
operational efficiency when combining equipment and software from
multiple vendors.
The goal of the Fujitsu Open ROADM solution is to drive innovation,
multivendor capabilities, and increased flexibility in metro networks.
The solution provides a field-proven implementation of optical layer
flexibility with software control that is fully-compliant with the Open
ROADM MSA specification. The open, modular functionality of the
Fujitsu 1FINITY and Virtuora platforms enable network operators to be
more interoperable, innovative and ultimately, more competitive.
