clarification regarding singlemode/multimode patch cable
« on: March 15, 2007, 07:51:40 am »
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

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..

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.
