We recently encountered a problem regarding fiber optic modules and connectors. We plan to overhaul our very simple network infracstructure using Cisco Switches. Done some research and stuff about the product line. We ordered 3750G for our core and a 2960Gs and ordered all GLC-SX-MM, thinking that all of them uses the same types of connections. However, when we are about to deploy them, we noticed that our fiber optice connectors do not match with that of the GLC-SX-MM. So instead, we researched about the connector that we encountered. Upon research, we figured out that we currently use an MT-RJ connector, whilst the GLC-SX-MM requires an LC connector, if I got that right. Question is, if there is any module that could accomodate MT-RJ connectors.
P.S. We also have SC Duplex Connectors too. Are there any other that could also support SC Duplex connectors for 3750Gs and 2960Gs? I guess this would be what you call a newbie mistake in cabling.
