POPULARITY OF GIGE VISION

Nearly every modern computing platform has a Gigabit Ethernet port: Built-in “frame grabber”

Costs driven down by use of GigE in consumer and IT markets : Cisco, Intel, Apple, Marvell, Broadcom, etc.

Simple and long-distance copper cabling with fiber option

Good fit for a variety of formats: VGA, NTSC/PAL, thermal, 720p/60, 1080p/25, anything used by USB 2.0

Standard scales to 100 Mbps, 10 GigE, 802.11

Distributed processing capabilities for advanced systems

CHALLENGES FOR GIGE VISION

• Sensor data rates are becoming faster • 1080p/60 (color), faster frame rates, greater pixel

depths

• 10 GigE adoption has been limited to high-end systems • Expensive cabling infrastructure (SFP+ modules) • Power and heat concerns

• Majority of demand for data rates above 1 Gbps is for rates below 2.5 Gbps • Which transport technologies can be used for

these data rates?

HIGH-SPEED WIRELESS

Consumer and IT devices using IEEE 802.11ad in late 2016 or early 2017 • Mini PCIe WiFi modules for laptops, PCIe cards, routers

Uses 60 GHz band • Avoids interference from IEEE 802.11a/b/g/n networks, cellular communications, cordless telephones, microwave ovens

• Allows for setup of multiple non-overlapping (non-interfering) wireless networks

Short range • About 20 meter maximum • Within the same room – 60 GHz doesn’t penetrate walls very well

Should achieve 2-3 Gbps sustained data rate • 2x–3x the speeds of wired GigE Vision

• About the same speed as USB3 Vision

FASTER THAN GIGE WIRED ETHERNET

• Broadcom introduces 2.5 Gbps “Ethernet” links in 2007 • Need Broadcom PHYs at both ends of the cable

• No IT/consumer support for this, resulting in no products developed using that PHY

• MGBASE-T • Consortium of companies led by Broadcom, Alcatel, and others

• Missing some of the bigger networking players in the business

NBASE-T

• New standard for adopting 2.5 GigE and 5 GigE solutions over 100m Cat 5e cabling • Happy mediums between 1 GigE and 10 GigE

• Supports PoE

• Consortium includes Cisco, Intel, Freescale, Xilinx, Altera, Marvell, Vitesse, and others

• Born out of the need to put 802.11ac onto enterprise networks • 10 GigE overkill

• Leverage the 70 billion meters of Cat 5e / 6 cabling laid between 2003 and 2014 • Inexpensive, long-distance, flexible, field-terminatable…

NBASE-T

• IEEE 802.3 standardization process ongoing • Intel and Cisco products starting to appear on the market now

• First plugfest completed to demonstrate cross-vendor interoperability • NIC vendors preparing for market launch

• Standard can negotiate 1, 2.5, 5, 10 Gbps • 1, 2.5, 5 Gbps over Cat 5e • 10 Gbps over Cat 6

• GigE Vision standard is agnostic to physical layer • Compliant software should need no change

CONCLUSION

• Adoption of 1 Gbps data rate strong & shows little sign of slowing

• Demand for sensors exceeding 1 Gbps is new reality

• Best way to handle these speeds is through continued adoption of technologies born in the IT and consumer markets • Leverage economies of scale

• Larger markets solve technical and distribution challenges

• New speeds on Ethernet roadmap require no changes to the GigE Vision specification • 2.5 and 5 Gbps should be readily adopted by the market
