Stratix V EDC Support for Linear / Limiting Optics

Hello, 

 

 

The purpose of my inquiry is to assess what the hardware design requirements are for the implementation of SFP+ and QSFP+ optics when using Stratix V. In our application, we require support of both SFP+ (10GbE) and QSFP+ (40GbE) optics. 

 

I would like to obtain a further understanding of the Stratix V transceivers as it relates to support of these standards. In particular, I need to understand the requirements for external dispersion compensation and CDR in the case where non-retiming optical modules are used. Thus, my questions are: 

 

[1] Do the Stratix V transceivers incorporate EDC? 

[2] Do the Stratix V transceivers fully support non-retimed optical modules without external dispersion compensation or an external CDR chip?  

[3] If support is available for non-retimed modules does Altera specify the maximum number of inches of copper allowed between the SFP+ / QSFP+ cage and the balls on the Stratix V package? 

[4] Do the Stratix V transcievers support both limiting and linear modules? 

 

Thank-you for your assistance with this. 

 

Best regards, 

James
