Early Adoption• High capacity backbone networks• Not widely used by consumers• Too expensive for desktop use• GbE could not be utilized (PCs too slow)• 20% - 30% network utilization• 200Mbps actual throughput• Unreliable over Cat5 cables

Market Growth• Prices have dropped dramatically• Implementation over Cat5e cabling• Faster PCs

Increased Productivity
• Through a multitude of technological advances, GbE has provided great advances in data
transfer rates.

Uses for GbE• Digital photography • Satellite imaging• Faster database access• Streaming video• Real-time file transfers• Back-ups

Media Types• 1000BASE-SX and 1000BASE-LX over fiber.• 1000BASE-T over copper. (1000BASE-CX)• Switched full-duplex only.

GbE over Cat5e• Older standards (10BASE-T and 100BASE-
TX) did not use all four pairs of wires.• 5-level pulse amplitude modulation (PAM-5)
allows multiple
signals to be sent.
125 megapulses
per second.

Optical• Optical wiring uses fibers of glass or plastic• Total internal reflection allows rays of light to
travel through the core, reflecting off the cladding.

Beyond GbE• Seven different media types• 10GBASE-T over Cat5e, Cat6, and Cat7• All other media types rely on fiber-optic
transmission.

10 GbE and 40 GbE• By using multiplexers with optical wiring,
speeds up 40 GbE may be obtained.• With wavelength division multiplexing,
separate colors are multiplexed, sent together, and de-multiplexed at the receiving end.

100 GbE• Recent technologies have broken the 100
GbE barrier.
