Description
SFP (Small Form-factor Pluggable) is a type of transceiver used in networking to connect a device, such as a router or switch, to a network. It is a small, hot-swappable module that sits inside a device and allows it to connect to different types of networks, such as Ethernet, Fibre Channel, or SONET.
The table below shows the list of SFP modules tested with Grandstream Layer 2+ managed network switches GWN780X(P) Series

Frequently Asked Questions
Why can SFP Modules support 4 ports but RJ45 can support just 2 ports at the same speed?
This is because the RJ45 module generates much more heat than fiber optic, if we plug 4 x RJ45 modules, they will stop working due to the high heat, so we limit RJ45-10 modules to 2.
What does “RJ45-10G modules must be interval inserted” mean?
It means these 2 RJ45-10G modules cannot be plugged one close to another, but you need to leave at least 1 port in between un-plugged for heat sink purposes, you can plug the 2 RJ45-10G at ports 1 and 3, or 2 and 4, or 1 and 4.
If I plug RJ45-10G modules at ports 1 and 3, can I plug SFP modules at ports 2 and 4?
It is not recommended as we need the port gap for heat sink purposes.
