Here is a link that shows where you can mix MM with SM and if a conditioning patch cord is needed (refer to Table 6).

Hope that helps.

Hello Sivakumar,

it doesn't work :

SM fiber acts as a narrower filter and will drop most of optical energy of the MM transmitter.

You need SM GBICs or SFPs to use SM fiber

Hope to help
