SFP module 100mb, smf for WS-3850-12S

[homosapiens1988]

I didn't find compatable sfp module for WS-3850-12S in "Cisco Optics compatibility matrix" for operate in smf 100mb. Is there any sfp to use in smf 100mb for this switch?

Kindly contact TAC.

I don't have a service contract.

What if I use GLC-FE-100LX. What will happen?

The GLC-FE-100LX might work. It is a 100 Mbps transceiver for use with single mode fiber spans up to 10 km. However at US$250 list price it will be an expensive gamble if it doesn't work out.

I would suggest trying a much less expensive third party model first. One like this:

...is only US$7.50 list price.

Reviewing the Transceiver Compatibility Tool, the following 100MB SFP is listed:

Now I see you were looking for a SMF interface (vs MMF).
