2 Supplier of Mixed Signal Products Supplier of Mixed Signal Communication Semiconductors, public $230M Medical Communications Wired Communications Wireless Technology for Medical Telemetry Systems Timing and Voice Enhancement Products for Access, Residential and Enterprise Markets Optical Interconnect Modules, IC & Components for Data Centers Optical Communications [Page 2]

3 Scope Embedded Optical Micro-Cables Active Optical Cables (AOC) Receptacle Optical Transceiver Modules Ultra-short reach Intra-board/chassis connection OEM only (not end-user) Nascent market Sub-100m, Point to Point, EOE, powered electrical receptacle Multiple users: Switch, server, peripheral, VAR, end-user Market first in HDMI, now taking off in Data Centre Sub-300m, Point to Point or Structured, optical receptacle Well established market To date: 850nm VCSEL based, hybrid-packaged Zarlink supplies: AOCs, transceiver modules, array-vcsel, array-pmd ICs [Page 3]

4 Market Pain: I/O Bandwidth Tremendous growth in processing and storage capacity I/O density/capacity cannot keep up Bottleneck today and in the future will be Interconnects Processing Power Storage Capacity I/O Capacity bottleneck [Page 4]

5 Customer Pain in the Data Center Problem: copper cables limited to maximum radius of 10 meters Problem: Signal loss and noise over copper wire limit the reach of server clusters Problem: Equipment density increases cooling requirements and power concerns Problem: Increasing bandwidth requirements results in cabling congestion Solution: Active Optical Cable Extends reach, weight and flexibility benefits simplify cable management [Page 5]

6 Active Optical Cable is the Solution Extended reach up to 100 meters Reduces installation times, improves airflow management and eliminates weight-related layout concerns Bend radius of 25 mm, a 60% improvement compared to 24-gauge copper cable 80% lighter than copper solution On the market < 12-months already in excess of 20k active optical cables shipped [Page 6]

10 The Optical Advantage: Copper vs AOC New metrics describe the AOC value proposition Reach-bandwidth (Gb/m) Power (Gb/W) Linear Density (Gb/cm of bezel/faceplate) Size (Gb/cm2) Weight Parallel fiber ribbon will be the #1 interconnect medium in the data center, bounded by copper at very short reach and CWDM for up to 10 km reach Data center interconnect implementation Today Future Comment System-System Parallel optical Parallel optical 100GE Rack-Rack Parallel optical Parallel optical Proprietary Shelf-Shelf Board-Board Chip-Chip Copper/Parallel optical Copper Copper Parallel optical Copper/Parallel optical Copper/Parallel optical Fiber ribbon to support GB Not standards driven Open for innovation Courtesy: Cray [Page 10]

11 Receptacle Transceivers vs. AOCs Fiber receptacles & terminations are expensive Optical Receptacle Transceiver Modules Specs require: fiber insertion/loss, cleanliness, eye safety, multiple grades of fiber, source spectral, flux Manufacturers have to meet receptacle transmitter & receiver standards Standards require 100s of meters of reach Different modules for data rates & standards Active Optical Cables Plug-and-play for customer, a light pipe with I/O electrical No optical standards to meet for manufacturer Sweet spot for cables in 10G + applications is around 20-40m Cables that operate at higher data rates will work at lower rates [Page 11]

12 AOC NOT limited to Pt-Pt application AOC currently deployed in point to point HPC Cluster and Display applications Transition to powered patch panels - driven by Power over Ethernet (PoE) and Embedded Media Converter applications is expected to propel AOCs into the structured cabling environment [Page 12]

13 AOC Technology Classes Lens-based coupling Solutions PCB-based SMT solution or wafer Separate VCSEL and PMD ICs Can use direct attach to PCB or via wafer-scale manufacturing carrier Commercial bulk-optic lens solution Established volume technology Fiber-Based coupling Solutions Carrier for ICs and photonics Use of fiber-based lens-less coupling e.g. Use of Si v-groove Reduced BoM Silicon Photonics Carrier & Waveguides Partially monolithic: ICs, photonic carrier and passive guiding in Si Non-VCSEL based, SMF Flip-chip of high-performance DFB Additional fiber structure for coupling General trend to wafer-scale sub-assembly
