Fortigate 80E Multimode Fiber Optic

Hi All,

I'm having Fortigate 80E firewall and have configured ports 2&3 for income and outcome interfaces for Modbus communication.

My client is asking me to connect the outcome interface using Fiber Optic (not RJ45 Ethernet).

1. I'm wondering can I purchase Multimode F.O transceiver and use it directly in the port?

Moreover, I can see in my Fortigate 80E that there are two ports (WAN1 & WAN2 shared) that can be connected through fiber optic. Can I configure WAN1 or WAN2 as physical interface and assign a policy to one of them to achieve F.O connection requirement of my client?

I need your support please.
