Gigabit Optical Ethernet ECE 4006 C Spring 2002
Gigabit Optical Ethernet ECE 4006 C – Spring 2002 – G 1 Team Ryan Baldwin David Gewertz Geoffrey Sizemore Presented : February 5, 2002
Gigabit Optical Ethernet Synopsis l Ethernet’s History l Ethernet Details l Fiberoptic Ethernet l Cabling Overview l Fiberoptic Technologies l Project Goals and Conclusion
Gigabit Optical Ethernet invention in Xerox Palo Alto Research Center by Dr Metcalf – Coincided with the introduction of personal computers l Initially 3 Mbps, standardized at 10 Mbps l 1 and 10 Gbps on the horizon
Gigabit Optical Ethernet l Bandwidth – 80 -20 rule – Ethernet vs. ATM or FDDI l Backbone, desktop l Backwards compatibility – OSI stack – Physical layer l Connectors and cabling
Fiberoptic Gigabit Ethernet l Fiber is replacing UTP cable l Why? – Better performance characteristics over longer distances For Gb data rates: UTP < 100 meters Fiber < 260 meters – Higher bandwidth capabilities – Integration with fiber backbone
Cabling Overview l Four mediums: 2 Fiber-based, 2 Copperbased (1000 Base. SX, 1000 Base. LX, 1000 Base. T, 1000 Base. CX) l Fiber allows greater distances, Copper offers greater flexibility
Cabling Technologies
Fiberoptic Market Charts from KMI Research Corp.
Project Goals l Maintain current testbeds l Evaluate testbeds using MAXIM kits l Design alternative solution l Conclusion – Fiberoptic technology beats copper – The challenge is making it cheaper
