I have some Catalyst 3560 switches that I need to connect over a long distance. The existing backbone is 62.5 850nm multimode and unfortunately I dont have the option of installing single mode fiber at this point. The distances range from 2000' to 6000'.
My question is - is this possible? and what parts would I need to make this work at 1GB/s?
I'm looking into the possibility of using a mode conditioning cable on both ends and a single mode SFP adapter for the switches. However, all I can find on the mode conditioning cables reference 1300nm and our existing fiber is 850nm. Is this a limitation of the existing fiber? Are there mode conditioning cables that support 850nm or does the SFP dictate what wavelength we are using?
Thanks in advance!
