My team and I are trying to use send data via a transceiver we bought (the Cisco SFP-10G0SR Compatible 10GBASE-SR SFP+ 850nm Optical Transceiver Module). We are planning to use it on an FPGA board, but we don't know how to get started with it. Can anyone help us get started?
From what we see on the transceiver datasheet, there are 20 pins total. Some are power/ground pins while others are signal/status pins. In terms of communication, it seems that I can either communicate with the transceiver through I2C (via my FPGA board's I2C pins) or I can use the TD +/- and RD +/- pins to perform differential signal communication with them (directly through my FPGA). Is that correct? What can I do to best maximize usage of my transceiver? For something like large scale transmission, are TX/RX generally used?
