Dynamic Wavelength Routing: The Sensible Approach to ROADM (UK English/A4) (pdf)
ROADM systems add an all-optical switching capability to the network that can be extremely valuable to carriers. The agility to switch, drop, and add traffic at the optical layer becomes more important as service bandwidth profiles approach the 10 or 40 Gb/s data rates of a wavelength. Ciena's CN 4200 ROADM saves immediate capital expense and provides the scalability to defer the cost of adding bandwidth on the network.

Wholesale Optical Services (pdf)
Today’s wholesale optical services market is driven by two fundamental factors. First, IXCs with long-haul WDM infrastructure that offer Metro-to-Metro connectivity but do not have direct access to all customer buildings. Second, LECs—particularly competitive service providers and even cable MSOs—that offer managed optical services within their Metro networks but cannot attract large enterprise accounts because they are unable to offer services between Metro regions. Ciena’s Wholesale Optical Services solution breaks both the cost and bandwidth barriers of traditional solutions with high-speed, highly scalable, carrier-grade optical Ethernet. Based on the CN 4200™ FlexSelect™ Advanced Services Platform, ITU G.709 compliant OTU Digital Wrapper technology allows the Ciena solution to transparently manage other protocols across the network on a single wavelength.

Ethernet Compression (pdf)
Enterprises IP networks that connect multiple locations across long distances often use Ethernet as the protocol of choice, because it provides high throughput to key data center applications. This demand for inter-data center connectivity continues to grow as enterprises support more remote applications, and they must do so with limited budgets and without allowing IP congestion issues to affect application performance. Ciena’s CN 2000™ Storage Extension Platform is a powerful solution for IP congestion issues at the edge of the data center, because it maximizes WAN efficiency and provides increased throughput, while leveraging existing assets without requiring additional WAN bandwidth.

Fiber Relief (pdf)
Over the years, cable operators have deployed and consumed many fiber strands between the headend and hubs as well as between headends in a region. This capacity problem has not been solved and today, bandwidth demand is growing faster than ever due to VOD, HDTV and new high speed data applications. Deploying new fiber is an lengthy, expensive process that delays service roll out. Ciena solutions can provide the added capacity to existing fiber that MSOs require for new service applications.

Wireless Backhaul (pdf)
Wireless Operators spend over $3B accounting for approximately 50% of their operational expense on the leasing of T1/E1 lines for connecting the wireless base stations back to their Mobile Switching Centers (MSC). To reduce this cost, wireless operators desire an alternative to the Local Exchange Carriers that charge approximately $450 per month per T1 in the US. Cable operators, due to the proximity of their HFC plant to the base station locations, are well-positioned to compete for this revenue stream. However, to offer a competitive service requires reliable transport of T1/E1 traffic over the metro area - including sub 50 millisecond protection switching - based on more cost-effective technology than the SONET/SDH systems that the incumbents utilize.

Video On Demand (pdf)
Video On Demand (VOD) has become an effective tool for reducing churn and competing against satellite providers. As it continues to expand from “Movies On Demand” to “Everything On Demand”, it also becomes an important revenue stream. The growing significance of VOD means that it must be a reliable, high-quality service with low latency and jitter and no packet loss -- even as tens of thousands of video streams are transported from the headend to distribution hubs. Ciena solutions ensure a cost-effective build out that minimizes the use of fiber assets and enables switching of content from any server at the headend to any service group QAM resource at any hub.

Supporting Triple Play Services on a Converged Network (pdf)
Operators are bundling voice services along with their existing digital video and high-speed data services on the same broadband connection. Because all of these services are packet-based, it makes sense to transport all of them on a common network infrastructure. Cable operators can use an Optical Ethernet solution from Ciena to create a highly scalable, yet cost-effective “triple play” network that provides the service availability and QoS necessary to support all three service types.
