Optical Cable 11010001 Flash Interval decides the speed. Optical Power decides the distance. PHY (Physical) Protocol | Datalink • Standard Protocol – SONET/SDH | ATM + SONET/SDH – SONET/SDH | Ethernet + LAN PHY – LAN PHY | Ethernet

Long Distance Communication • SONET/SDH – 45M, 150M, 640M, 2.4G – ATM shaper • 1M,2M,,,,8M,,,, – Expensive • Ethernet (WAN PHY ‐ > LAN PHY) – 10M, 100M, 1G, 10G, 100G – Cheap 2001 ‐ 2012 • APII + α • JP ‐ KR APII R&E Network • 2002 – SG, TW, AU – 8M: ATM • JGN International (2006 ‐ ) » 8M << Audio Visual 2003 – JP ‐ TH, JP ‐ SG • 1G: Gigabit Ethernet – • TEIN (2006 ‐ ) 1G > DV (SD) » – China, India, Indonesia, • 2008 Japan, Korea, Malaysia, 10G: 10Gigabit Ethernet – Nepal, Pakistan, the 10G >> HD » Philippines, Singapore, Sri Lanka, Thailand, Vietnam, Australia, Bangladesh

Optical Cables in the World 7 Networks and Infrastructures after 2013 • Backbone: 100G Ethernet – Enough for Most Usual Applications • Cloud is one of important keyword for the future infrastructure. – High Speed Communication by Direct Connection to Backbone – No Physical Device – Cheap – Easy Operation • Human Resource
