1.7.1. Optical Platform
The FPGA application implements the Ethernet MAC, the 1000BASE-X PCS, and an internal system using Ethernet connectivity. This internal system retrieves all frames received by the MAC function and returns them to the sender by manipulating the MAC address fields, thus implementing a loopback. A direct connection to an optical module is provided through an external SFP optical module. Certified 1.25 GBaud optical SFP transceivers are Finisar* 1000BASE-SX FTLF8519P2BNL, Finisar 1000BASE-LX FTRJ-1319-3, and Avago Technologies* AFBR-5710Z.
