Clarification regarding singlemode/multimode patch cable



  • Hi all,
    Would like to clarify the following doubts:
    what would be more preferred to be used as a fiber patch cable (cable from fiber patch panel to switch)  - singlemode or multimode? and why?

    adios,
    haze

  • Single-mode fiber and interface modules tend to be much more expensive than multi-mode.  I’ve personally never used single-mode within a datacenter.  The only single-mode I’ve even seen was usually some sort of OC drop from a carrier.

    The question that more often comes up is which type of connectors to use with MM fiber - SC or LC.



  • it depends on what laser source you are working with. At the simplist level if its a single mode laser you want single mode cables and vice versa…

    you can get away with differing combinations with certain caveats but dont worry too much about that for now…
