Library Transceiver

This library provide an application-independent API to get/set information from/to a transceiver compliant with the SFF Committee specifications.

More Info

This API is compliant with these MSAs:

• SFF-8472 rev 11.3 (SFP/SFP+) (ftp://ftp.seagate.com/sff/SFF-8472.PDF)
• INF-8077i rev 4.5 (XFP) (ftp://ftp.seagate.com/sff/INF-8077.PDF)

More information about MSAs are in the SFF Committee Spacifications page.

SFP internal devices (both memories and PHYs) are accessed by I²C bus. These accesses are application-dependent, so the API user must register a couple I²C read and write callbacks, to perform these actions.

Implementation

The libtcv is developed in C.

Requirements

• Application-independent;
• Platform-independent;
• Read/Write I²C callbacks;
• User transparent devices read, write and refresh;
• UTs;
• Support XFP;
• Support SFP;
• Support SFP+;
• Support TCV internal PHY configuration.
