I replaced the lx sfp and everything started working. Bad hardware. I'll award the points anyway cause I hate it when people screw me out of points.

I have a Catalyst 4506 SupIV that I am connecting to a 3750 via fiber.<br />
<br />
The 3750 uses the LX SFP. &nbsp;The 4506 uses the regular SFP. &nbsp;I have a mm fiber cable connecting the two.<br />

I do not get link.<br />

I have tried 'no shut' and setting the speed statically; however, nothing is helping.<br />

Ideas?

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
