Converting Multi mode Fiber 100Mbps to FastEthernet

[admin_2]

Please advise me! I have an install of one possibly two 4003 L-3 switch as core, and several 2950 access switches installed around the campus. The customer wants 100Mbps Multi mode Fiber cable to connect to the cabinets in the different buildings on campus. Reason for this is the distance from the core switch to the various buildings exceeds 100 and even 200 meters. Can the 100Mbps MMF be converted in the cabinet to connect to FastEthernet ports on the 2950?

Yes, you can. There are a number of companies that make media converters, including BlackBox (www.blackbox.com) and Signamax (www.signamax.com).

If you look around you can find pretty much anything-to-anything (within reason).

Good Luck

Scott

Fast Ethernet over multimode is limited to 412m in half duplex (think hubs) but can reach out to 2,000m in full duplex. Make sure you can run both ends of the link in full duplex to get the most distance out of the fiber.
