Business need

Your future revenue growth relies on hot applications like VOD, HDTV, tiered data services, video telephony and gaming—but you may be running out of available fiber just at the time when you need to expand capacity.

Challenges

Over the years, cable operators have deployed and consumed many fiber strands between the headend and d-hubs as well as between headends in a region. This has occurred primarily because each new DVB-ASI, SONET, ATM or POS ring built to increase network capacity required its own dedicated fiber or fiber pair. As optical rings run out of fiber, you need an alternative method to add capacity without the lengthy and expensive process of laying new fiber.

Solution

You can now implement Ciena’s sub-wavelength add-drop and SONET/SDH Wraparound technologies to reclaim fiber assets and postpone or avoid the need to deploy new fiber—so you can reach residential and commercial customers faster and more efficiently with the high-bandwidth services they want today.

Ciena's offerings

Ciena offers the most flexible sub-wavelength ROADM together with a low-cost, high-quality Optical Add-Drop Multiplexing (OADM) system that that reduces the number of wavelengths required for a typical metro network by up to 78 percent while adding up to 40 DWDM wavelengths to currently-lit fiber. With FlexiPort technology to allow any port to be software provisioned for any protocol (OC-3/12/48, STM-1/4/16, GbE, 10/100baseT, Fibre Channel and more) Ciena’s solution provides fiber efficiency at half the cost of traditional DWDM solutions.

Benefits

• Reach subscribers ASAP with a greater choice of high-value services
• Delay or avoid time-consuming and costly fiber buildouts
• Add up to 400 Gb/s of capacity to already-lit fiber in modular increments
• Increase capacity without disrupting existing services
• Realize a four-fold gain in effective capacity versus traditional DWDM systems
