1. Plc Oxford & Cambridge Club 21 May 2014 CSS INVESTOR PRESENTATION “To become the world leader in supplying optical chips to the active optical networking market”

2. From Copper to the New Order

3. The Future is Optical The world is moving to optical communications that is replacing electrical communication because copper lines are limited in transmitting high speed signals, over medium to long distances. Optical communication will dominate the line communication market in the near and far future. The problem companies are facing is how to make the translation between electrical and optical signals a low cost solution. OTX breakthrough solution: “Optical Chips” The translators (TOSA and ROSA) are made in a “silicon chip production” fashion, making it: Low cost Easy to assemble Widely spread With OTX optical “chips” manufacturers can make low cost: HDMI active optical cables USB3.0 active optical cables Any other fast communication line connection OTX provides low-cost optical solutions for mass market

4. Optical Communications OTX makes “translation” units available to mass market High speed cable Electrical signals Electronic equipment (PC, TV, etc.) Standard interface (PCI-X, USB3, HDMI etc.) Electronic equipment (PC, Server etc.) Standard interface (PCI-X, USB3, HDMI etc.) “Higher Speed and longer distances” High speed cable Electronic equipment (PC, TV, etc.) Standard interface (PCI-X, USB3, HDMI etc.) Electronic equipment (PC, Server etc.) Standard interface (PCI-X, USB3, HDMI etc.) Optical signals Electrical to Optical (TOSA) and Optical to Electrical (ROSA) translation unit

5. OTX was founded in March 2007. Its mission to create a new Production Platform for the assembly and manufacture of integrated Optical Circuits used in implementing active optical networks. To use this Production Platform to make smaller, simpler and cheaper “optical chips” consisting of lasers and photodetectors for active optical applications. The R&D phase lasted five years. The OTX Production Platform technology was completed and the optical chips it made passed all the tests for telecoms application. In 2014 we started integration process by engaging with Chinese optical cable manufacturers to refine OTX translators to facilitate their production process. Background to the Company

6. Accomplishments to Date 1.OTX has validated the proper functioning optical chips produced by its proprietary platform. Chips have been subjected to conventional heat, stress, vibration tests and passed them all with no exceptions (2011-12). Even qualifying for use in telecom infrastructure. 2. OTX has completed its R&D Production Platform line in Israel (2012-13). Consists of two automated machines that make the laser-emitter chips and photodetector chips respectively, operated by one PC. – Theoretical upper limit for one machine is 3,600 chips per hour – 1 machine operating 10 hours/day for 30 days can manufacture 1 million chips per month – Cost of one machine < US$ 5,000 dollars – No limit on scalability, just add add 1 PC every 4 machines 3. Throughout OTX has maintained IP policy of patenting the uTOSA/uROSA specific geometries and layout (one patent awarded on chip design in 2012); combined with a strict trade secrecy policy over the OTX Production Platform designs, its methods and construction. 4. In 2013 OTX market approach focused on singlemode Active Optical Cables and we have integrated our two chips in a stand alone “translator” component for ease of assembly by HDMI and USB cable manufacturers. The so called OTX micro-OTR (or uOTR).

14. USB 3.0 Future Until recently Ethernet cables dominated the Local Area Networks (LANs) and USB cables is dominating the peripherals interconnect for many years. Started with USB 1.0-10Mbps, USB 2.0-480Mbps, USB 3.0-5000Mbps, USB 3.1- 10,000Mbps. USB deliver both Power and Communication on the same cable. USB is supported by all Electronics products in the market. USB 1.0 and 2.0 where limited to few meters. But USB 3.0 standard is no longer distance limited which makes it superior over Ethernet. Therefore position the USB as the dominating interface in the years to come. Conclusion USB 3.0 and it successors will dominate the interconnect. 5Gbps and higher bandwidth require optical fibers for distances more then few meters. (Optical Fiber are cheaper then Copper for more then few meters applications) Current Optical cables are using multimode fibers which are more easy to assemble but suffer from poor performance when bandwidth/distance increase.
