Chris Abbott

2. Current Status Ordered VCSEL and ROSA Began researching board design
Started Rx schematic
Finished optical link budget
Priced critical passive components
Basic web site

3. ROSA vs PD
Mix-up with OSI Fibercomm made #1 PD and ROSA prohibitively expensive
ROSA drastically simplifies Rx circuit

4. VCSEL Selection
Lasermate TSC-P85A426-2
SC connectorized
$32, in stock

5. ROSA Selection
Lasermate RSC-P85P416
SC connectorized
$36, in stock

6. Four Corners Analysis

7. Limiting Amp Input Minimum

8. Optical Link Budget

9. Passive Status $90 budget for passives Found SMA vendor ($4.50/unit)
Found ferrite bead vendor ($0.10/unit)
Biggest cost problem is SMA connectors

10. Gantt Chart

11. Tasks for This Week Submit schematic for review
Determine passive needs
Order passives
Research layout design considerations
Begin board layout
Create website
