topic GBIC support of 50 Micron in End of Service Products https://community.extremenetworks.com/t5/end-of-service-products/gbic-support-of-50-micron/m-p/24639#M549 Hello, I am curious if the GBIC for B3, B5, C3 and N series switches support both 62.5 and 50 micron. We have some LC01's currently being used and they are using a fiber for 62.5. I was wondering if they also supported multimode 50 micron fiber as well. Thank you!
