Hi @ishaq373 

Thanks for posting in our business forum.

We have users replacing their ISP-provided modem with an SFP module.

But this depends on your ISP.
You have to address at least two issues at this moment:

1. Specs of the fiber from your ISP.

2. If they require a modem or you are allowed to bypass the modem to make a direct connection.

I have attached my main ISP router configuration screen shot further my ISP doesn't have any problem for replacing the main router with ER707-M2 

So kindly advise me which SFP module is suitable for me as per attached screen shot 

Thanks 

This is software. Tells nothing about the fiber you have.

As replied earlier, you should know them from your ISP before you pick a module.

If you have a single-mode fiber, get a single-mode, and choose the proper fiber wavelength.
