2. What is the REVOL(TM) PRIZM® LightTurn® Connector • Miniature multi-fiber connector interface for parallel optic VCSEL / PD arrays • Monolithic ferrule accepts up to 12-fibers • Incorporates a molded photonic turn TIR lens array • Simple, low-cost fiber termination with no polishing required • Integrated posts provide passive alignment to the optical module • Precision connector housing latches provide multiple re-matings into the board level optical module • Hardware options are available for terminating bare ribbon fiber and jacketed cable

3. The Value of PRIZM® LightTurn® Technology • Small form factor enables increased board component densities • Facilitates increased card edge densities • Lowers termination cost • TIR lenses redirect the light path at approximately 90° to the fiber axis improving board level optical cable routing • Housing accommodates stacked ribbons for dense tiling of optical modules • Reliable, consistent, and repeatable mating interface to the optical module

4. Ferrule & Termination

5. Low Cost Termination Process • A low-cost no-polish termination • Cleave only fiber array inserted into PRIZM® LightTurn® ferrule • UV or Thermal cure epoxy added • One piece connector housing installed • Assembly complete and ready for testing

6. PC Board Configuration PRIZM® LT Housing provides protection for the ferrule lenses and multiple matings into the MOI PRIZM® LT ferrule for fiber termination and light coupling between the fiber and MOI (one part for Tx & Rx operation) Mechanical Optical Interface (MOI) provides the mechanical coupling of the PRIZM to the VCSEL/PD array and facilitates light transfer between the PRIZM ferrule and VCSEL/PD array (one part for Tx & Rx operation) Side View

7. Multiple Applications Use of common TxRx components allow for one optical engine to be employed in numerous applications Embedded TxRx AOC Pluggable TxRx

8. Lensed Ferrule Technology • Same outer footprint as traditional MT ferrule • Compatible with MTP® connectors and other MT based connector platforms • Connectors using PRIZM MT™ are backwards compatible to use traditional ferrules for low-loss applications • Lower mating force required ~2.5N vs. 10-20N • Rows up 16F wide – collimating lenses & microholesfor precision alignment • Row count up to 4F • Hermaphroditic, molded ~550 micron alignment posts • No polishing required – laser cleave only (same equipment as PRIZM® LightTurn®) • No endface geometry control or metrology required • Performance is stable with low spring load at high fiber counts

9. Lensed Ferrule Technology • Collimating lenses • Micro-holes for precision alignment • Same termination procedure as PRIZM® LightTurn ferrule • Traditional pins or hermaphroditic, molded guide post

10. Expanded Beam Interconnects Fiber to Fiber • Air gap in traditional connector results in multiple loss mechanisms • Loss penalty due to NA and divergent beam & core size • Fresnel reflections due to index of refraction mismatch Expanded Beam • Larger signal area means less impact of debris • Collimated light results in forgiving alignment in z-axis • Less spring force required • Endface separation losses due to fiber NA are eliminated • Stable return loss (≤ -23dB) governed by lens geometry & termination quality

11. Effect of Debris

12. PRIZM MT™ Vs. Standard MT Interconnects Why Prizm MT™ Ferrules 1. Lower cost - No polish - No end face geometry to maintain, measure - Lower spring force paves they way for simplified connectors - No precision guide pins necessary - All things being equal (volume, supply chain structure, etc.), Prizm MT™ is a lower cost interconnect solution 2. Debris Insensitivity • Expanded beam interconnects are less susceptible to signal occlusion due to debris. • PRIZM MT™ is less susceptible to Z-axis alignment/ physical contact issues caused by debris. 3. Z-axis stability • Lower spring forces necessary for proper ferrule mating • Stable IL and RL results can be achieved for high fiber counts with very low mating forces

13. PRIZM MT™ Vs. Standard MT Interconnects Why Traditional MT Ferrules? 1. Higher performance - Physical contact ferrules offer lowest possible insertion loss for up to 24 fibers per ferrule. - Minimum return losses when physical contact is achieved - Ideal for structured cabling or applications with long fiber runs, multiple connection points, etc. 2. Mature supply chain • MT Ferrules and MPO connectors are standardized with multiple global suppliers of components and cable assemblies
