Drivers for DWDM and Tunable Optics
Growing applications – cloud computing, video, driverless car,
IoT drive the need for higher bandwidth and more connections
Global IP traffic is growing 22% annually
Connections are increasing 10% annually (source: Cisco VNI)
Network densification in Metro-Access, Wireless, Cable networks
Increasing fiber constraints and high fiber costs
Burying new fiber cost ~$500K per 10km
Leasing and maintenance costs $250~$2000 per fiber annually
New standards defined Tunable Bidirectional DWDM networks
G.metro: 20~40 bidirectional Point-to-Point links
NGPON2: 4 channels TWDM-PON and 6~16 P2P WDM links
