Optical Gigabit Ethernet

• Group 4
• February 17, 2005
• 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

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
