Ethernet History

• Developed by Xerox in 1973

• Standard approved as IEEE 802.3 in 1985

• 1 Mbit/sec

• 10BASE-T (1990)

• 100BASE-T (1995)

• 1000BASE-T (1998)

• 10GBASE-T (2006)

• How has a technology which has been around for 45 years remained relevant?



Ethernet Advantages• Reliable

• Packetized data enables error correction and retransmission

• Fast

• Versatile

• Long cable lengths

• Multiple implementations

• Protocol enhancements

• Established

• Large install base

• Widely available

• Easy to use

• Standard is managed well by IEEE



Adoption of Ethernet

• Ethernet’s many advantages have contributed to its majority share of the Machine Vision market

From AIA 2016 Market Study



10GigE builds on GigE 10x more speed

• 10GigE provides a great balance of speed and cable length



10GigE supports the latest CMOS sensors

• 10GigE is supports popular Sony Pregius sensors at full resolution, frame rate and bit depth

• Bandwidth is available for the next generation of faster and higher resolution sensors



10 Gigabit Ethernet is lower latency than GigE

• 10GigE is lower latency than Gigabit Ethernet

• Low latency is key for real-time applications like closed hatch driving

• Lower latency can yield increased throughput on high speed processes



10 Gigabit Ethernet comes in different flavors

• Several 10GigE implementations are available

• XFP, SFP, SFP+ transceivers using optical and copper cables

• 10GBASE-T uses RJ45 connectors on twisted-pair copper cables

• 10GBASE-T has a rapidly growing install base



10 Gigabit Ethernet is going mainstream

• Apple iMac Pro

• Synology Network Attached Storage

• Asus Switches, Mainboards, NICs

• Singapore and UK trialing 10Gigabit home

10 Gigabit Ethernet



10 Gigabit Ethernet is Ready for Industry

• Rugged, industry ready 10GigE products are available

• This includes multi-port systems

• Two ports are common and systems with four ports coming



10GigE Machine Vision cameras

• 10GigE cameras are available from several hardware manufacturers now

• The FLIR Oryx is about 30% smaller than competing products

• Does not rely on active cooling or heatsinks making it compact, maintenance-free and easy to integrate

• 10GigE is faster than 2nd Generation Sony Pregius

• 5MP at 163 fps, 12.3 MP at 168 fps

• The Oryx is GigE Vision compatible

• Ensures third-party software support



Power over Ethernet

• GigE Power over Ethernet (PoE) hardware is widely available

• FLIR (formerly Point Grey Research) was the first to ship a 29mm x 29mm GigE PoE camera

• IEEE 802.3at used by GigE does not support PoE over 10 gigabit links

• IEEE 802.3bt enables PoE over 10 gigabit links

• Standard approved mid-2016

• Hardware is not widely available



NBASE-T

• The NBASE-T standard offers 2.5 and 5 Gbit/sec transfer speeds over CAT5e

• The cost of upgrading is similar, yet the performance gain is only ¼ to ½

• Much less favorable price to performance ratio

• 10GigE is more well established, and is being adopted faster than NBASE-T



10GigE System Configuration

• 5th Gen or newer Intel Core i7 CPU

• Standard i7 is OK

• Dual channel memory is key

• FLIR Oryx uses less than 1% CPU for a simple grab loop

• Recommended system specifications come from memory bandwidth requirements

• 10GBASE-T Network Interface Card

• Check to ensure PCIe slot does not share bandwidth with other slots or devices



Cabling requirements

• CAT6A cables are recommended

• Designed to reduce crosstalk at frequencies over 500MHz

• Shielded and pairs are more tightly twisted than CAT5e

• CAT5e is OK for distances less than 30 meters

• CAT6A is required for distances greater than 30 meters



Easily combine GigE and 10GigE hardware

• GigE cameras can be plugged into a 10GigE switch

• Enables designers and integrators to seamlessly mix resolutions and speeds within a system

• Simplify cabling requirements between cameras and host with a 10GigE switch

+



Network infrastructure

• FLIR Oryx and Blackfly S cameras use 9K packets

• This reduces packetization overhead to make for more efficient transmission

• Many, but not all switches and NICs support Jumbo Frames, so check first



Embedded Systems

• 10 gigabit Ethernet is not recommended for compact single board computers (yet)

• Memory bandwidth requirements are too high for most systems

• The Nvidia Jetson TX2 is a notable exception to this

• Custom filter drivers required for ARM Linux

• ARM Drivers for NICs are likely to cause additional issues



IEEE 1588 Precision Time Protocol

• Ethernet devices can support the IEEE 1588 Precision Time Protocol (PTP)

• PTP enabled Ethernet devices can synchronize their clocks to a common time base

• A Grandmaster clock is a high precision PTP master synchronized to the GPS time signal

• No user oversight needed

• Can be combined with scheduled software triggers



What’s next for 10GigE?

• Lower power Physical Layer (PHY) chips as lithography technology advances

• This is expected to yield further increases in power efficiency and smaller cameras



Oryx 10 Gigabit Ethernet Cameras
