HANOVER, Md. & PHILADELPHIA -- January 17, 2013

Ciena^® Corporation (NASDAQ: CIEN), the network specialist, today announced
that it is providing next-generation 100G coherent optical technology to
Comcast Cable for use in its core network. Ciena’s 6500 Packet-Optical
Platform equipped with third generation WaveLogic ^ coherent optical line
interfaces – the industry’s first software-programmable coherent technology
that scales to 400G – gives service providers like Comcast a cost-effective,
scalable way to further enhance their networks while supporting continued
broadband growth.

This deployment will help Comcast to continue satisfying growing customer
demand for high-speed, high-capacity services and applications, such as HD
video, mobile data and cloud computing. It also will help Comcast more easily
evolve its network and create energy efficiencies by reducing the number of
network components, including optical regenerators required in its network.

“Adding Ciena’s WaveLogic 3 to our already installed 6500 Packet-Optical
Platforms lets us leverage that investment to deliver more content, faster
Internet speeds and enable new cloud-based applications for our customers,
while also providing future core 400G scalability,” said Kevin McElearney,
senior vice president, Network Engineering, at Comcast Cable. “As we scale
beyond our 100G network, Ciena’s coherent optical technology will help us to
deliver on our ongoing commitment to maintain and operate a high-performance,
feature-rich advanced network.”

Ciena’s coherent optical technology, a critical component of the company’s
OP^n architecture, gives service providers advanced signal regeneration
capabilities and is programmable for capacity, reach and latency.

“Service providers are continuously looking for new ways to meet the needs of
their customers while extracting the most value out of their vast network
infrastructures,” said Francois Locoh-Donou, senior vice president, Global
Products Group at Ciena. “Through a combination of consultative customer
engagements based on network analytics and transformational planning, along
with state-of-the-art 100G technology, we are able to help customers like
Comcast transform network infrastructure so that they can meet escalating
bandwidth and service demands.”

Ciena is also providing Comcast with network management system capabilities
and a range of professional services via its Ciena Specialist Services
portfolio, including furnishing and installation.

Ciena and Comcast have a long-standing relationship. Comcast has been
deploying Ciena’s coherent 40G and 100G technologies across its national fiber
network since 2009. More recently, Comcast deployed Ciena’s packet networking
solutions to support its Metro Ethernet services offering. In addition,
Comcast Business Class, a division of Comcast Cable, is a Managed Service
Provider partner in Ciena’s BizConnect partner program.

Technology Background:

  *The industry’s first software-programmable coherent technology that scales
    to 400G, WaveLogic 3 coherent optical processors enable service providers
    to accelerate the move to dynamic, software-defined Terabit networking
    while improving network economics. WaveLogic-powered networks change the
    game in optical networking by making the optical layer more intelligent
    and responsive to application needs—an increasingly critical requirement
    in today’s dynamic and cloud-centric networks.
  *Ciena is the pioneer and market leader of coherent optical technology with
    20,000 coherent 40G/100G line interfaces shipped to over 100 customers
    across the globe, with more than 20 million coherent kilometers deployed.
  *OP^n is Ciena’s approach for building open, programmable next-generation
    networks that scale and automatically adapt to handle the changes created
    by cloud/data center migration, mobile broadband and the growing demand
    for high-bandwidth applications and services.
