10G WAN Connectivity on MX105

[rpidcock1]

I have an MX105 deployed at one of my branch locations that has a SMF (Single Mode Fiber) connection to my main office building.  I'm attempting to build 10G connectivity across that SMF, but have been unsuccessful to establish link.  Summary of my scenario below.

Main site has a 4500x, remote site has MX105, single mode fiber between locations.  I'm using an "SFP-10G-LR-S" optic on each side of the connection.  I have confirmed the ability to establish link to a 3850 switch at the remote site using the same optic and fiber.  

My question is, does the MX105 have a hard requirement to have a "MA-SFP-10G-LR" to establish this connectivity?  Will it be compatible to connect with the "SFP-10G-LR-S" on the opposite side of the connection, since the 4500x doesn't show support for the "MA-SFP-10G-LR" module?

Thanks in advance.

Replace the MX105 optical connector with a Meraki MA-SFP-10G-LR. The 4500X can retain the Cisco optical connector. This is the only reliable and supported way to establish the connection.

On Cisco switches, you can run commands to use incompatible GBICs.

But in general, as far as I remember, you can use most GBICs on both Meraki and Cisco's Catalyst line.

You have to use the same type of optics at each end of a fibre (and I am assuming this is a private point-to-point fibre, rather than something provided by a service provider).

If you use LR at one end, you have to use LR at the other end.  You might need to use different part numbers for different device models.

This is the Meraki SFP compatibility matrix.  This tells you what you can use on each device, fibre length restrictions, the laser wavelength, etc.  You consult this for the MX105 end.  "MA-SFP-10GB-LR" is a valid option for the MX105.

This is the same thing for a 4500x.  Without looking it up, it is likely you should be using "SFP-10G-LR" or "SFP-10G-LR-S" for the 4500x.  "MA-SFP-10GB-SR" is not likely to be a supported option for a 4500x.

If you want to use an unsupported SFP in a 4500x, then you'll need to use these commands (on the 4500x) to disable the checks.
