Supported SFP for fortigate 201E

Dear Folks;

I'm new in fortinet. we have fortigate 201E with 4 optical port. Which SFP will be suport for this use?

Is the cisco SFP (SFP GIG LX) or other SFP from another vendors (GIG LX) can use for this purpose? Is the fortinet issued SFP for their fortigate devices? I plan this optical port to used as wan connection, at least it will be used for LAN connection.

second question, could the 2 or 4 SFP port used as aggregate ether (ae or etherchannel) ini fortigate?

Many appreciated for your explanations

Thanks
