Large portion of my datacenter infrastructure currently consist of clusters using fiber storage on EMC SANs and Brocade fiber switches. There are also uplinks to data switches from core routers and all these different fiber connections use many different types of fiber connectors that at times confuse the hell out me. I am no cabling expert so I thought it would be nice if I can put it all together on piece of paper as a reference. Finally, I found this image in a document and thought would be nice to share it with all. It explains all major types of fiber connector types used in today's datacenters. Hope this will help someone else out there trying to go nuts between MT-RJ and LC-LC or ST-LC fiber connections.
