What is an Active Optical Cable?• Parallel optic transceiver in a standard MSA shell but… integrates

the fibers directly into the MSA• No optical connectors• Changes the game!

3 Fundamental Particles in Communications

3)Moneyatron

Moneyatron – is the God Particle!


What Makes an AOC Special?• Less expensive - to make an interconnection than using transceivers and

connectorized fiber

• Fiber attach: Interfacing fibers to lasers & detectors is difficult & expensive– Can represent 15% of transceiver cost

• Testing: Optical testing of transceivers >40% of the cost of manufacturing: AOCs aretested with electrical testing

• Fast time-to-market: 10+ AOC vendors 4x10G QSFP 9-12 months later only 4-5 paralleloptic transceiver vendors

• Interoperability: Designs do not have to be interoperable

Engineers are free to design with any technology

Interoperability:Designs donot have tobeinteroperable

AOC Technology PlaygroundUnintended Consequences

• 10G Parallel Optics typically employs standard 850nm VCSELs, and TIA,Laser Drivers, with MMF at ~100m

• AOC became a playground for new technologies to come to marketwithout having to deal with interoperability issues and industrystandards

• Wavelengths: 850, 1060, 1490, 1550nm• VCSELS & externally modulated CW lasers up to 25G………40G?• MMF, SMF and Polymer fibers• Reaches from 200mm to 4Km• Parallel, Serial …..CWDM, DWDM• Aggregate data rates: 10G, 14G 40G, 56G, 100G, 120G, 150G, ....400G• Protocols: InfiniBand, Ethernet, SAS, PCIe, HDMI, ThunderBolt, MIPI

1 Core AOC TechnologyCreates Multiple Products

• Multiple types– 1x10G SFP+ - 4x5G CX-4– 4x10G QSFP - 4x14G QSFP– 12x10G CXP - 12x12.5G CXP– 8 x 8G iPass

• Breakout AOCs: 4-SFP/QSFP and 3-QSFP/CXP• Embedded Optical Module (EOM) replacing SNAP12

– For inside chassis applications (no MSAs yet)

• Parallel Optical Transceivers• AOC/Transceiver: AOC with connectorized fibers• Use same parts & change the protocol: DisplayPort Optical, USB

optical, HDMI optical

8-Inch AOCs?Ultra-Short Reach

• Most high-speed interconnects use 40nm CMOS which can support 10Gbps SerDes to serializeparallel connections into a single wire – parallel cables becomes serial

• Video: Digital cameras, Tablets, Cell Phones are transitioning from 5M pixels to 12M, 16M, 20Mpixels; 2 cameras per device

– Use high Mpixels chips instead of optical zooms

• Radios: Number of radios and data rates are increasing from 2G to 3G/4G LTE, WEDGE, etc –promise 10-15X increase in data rates

• Wifi: 802.11N going to MIMO and WiGig @ 7GHz

• All of this is pushing internal interconnects of video and subsystems past 5.6Gbps

• Creating a very high RFI environment in an already high RF environment from the 4-10 radios

• Video displays – LVDS standard is running out of bandwidth beyond 1080p

8-Inch AOCs?Ultra-Short Reach

• iPad4, iPhone 6, 2014 class notebooks will haveserious RFI - EMI issues

• HDTVs, high-end video cameras, and othercommercial and consumer electronics will have thesame problem

OLD LVDS Low-Speed Parallel Interconnect Schemes

MEW MIPI/USB Serial Optical Interconnect Scheme


New Entrants + M&As Running Wild!• Cabling companies realizing the beginning of end of copper

for high speeds >10G

• TE Connectivity (Tyco) bought Zarlink• FCI bought MergeOptics• Molex bought Luxtera's AOC business• Samtec bought AlpenIO

• Big change: $XXB cabling companies selling transceiverscompeting against traditional transceiver cos

• New AOC vendors: Delta Electronics, GigaLight, Samtec• GigOptix & GigaLight selling AOC component kits

10/2/2011 36


Summary• The new AOC technologies coupled with the M&A activities and new

markets will change the much of the interconnect and transceiverlandscape going forward.

• 10G sound barrier is why the cabling companies bought AOCcompanies and got into the transceiver business

• Low cost AOCs spread outside InfiniBand HPCs to datacenters withEthernet, Fibre Channel, SAS, PCI Express

• AOC technologies spread inside the systems chassis.

• Spreading into consumer and commercial areas HDMI, USB, HDTV,Smartphones, Tablets, Notebooks, etc
