Hello Robert, I have a question for you. I need to design gigabit
ethernet fiber converter with 2 RJ45 ports and 1 fiber port. These
RJ45 ports will share time when they are communicating throug single
fiber cable. My fiber will be 1310TX/1550RX and vice versa at the
other end. I want it to be able to communicate up to 60km. So i choose
one of Marvell ethernet chips: 88E1543. My question is should i
connect sfp fiber module to its SGMII? Actually what i desire is using 1x9 1.25Gbps
BiDi transceiver but i don't know where to connect on the ic chip
(Serdes or SGMII or somewhere else). Can you help me with it? Lastly, what if i just
connect SFP fiber transceiver to SGMII and connect 2 RJ45 ports and
other ports left floating, do they start automatically communicate
with each other? Or do i need make extra things.
