fiber to the desktop - which connector

in putting together a new installation, one of the requirements is that we use fiber to the desktop. we are going to use multimode, but im not sure which connector.

is there a material (ie cost) difference between SC and LC? what about durability?

It would seem to me that the fragile part (the fiber) doesnt benefit much from either connector, so is either OK?

any other advice or things that seem obvious in hindsight would also be appreciated.

edited: also, if anyone has some insight as to which 1000baseSX nics one should avoid (if any) that would be most appreciated.

• The main benefit of LC over SC is the form factor. An LC connector is similar in size to an RJ45 jack whereas an SC connector is about twice the size.

  I have not found any differences in the durability of the connectors.

  ANervousTwitch : ultimately we will probably be going with SC because thats what the vendor is offering. thanks!

• It is worthwhile to note that with LC connectors, it is difficult to change the fiber pairs from crossover to straight through. SC is easier, and ST is obviously trivial.

  petertonoli : How is it hard to swap the fibre from crossover to straight through? Never had a problem here..

  ANervousTwitch : disassembling the connector without breaking the clip appears to be a challenge with LC connectors (at least the ones that we got). SC, on the other hand, was not very difficult. SC is also much more forgiving if the clip breaks, as the TX/TX connectors will still lock in on their own.

  LC basically, anything else is folly.

  Apart from not bothering given most machines struggle to saturate a 1GBps copper GigE link both ways, even then what is going to offer you fully non-blocked transit out of there other than multiple Cisco Cexus 7000/5000's?

  But if you want to waste your cash then the answer is LC.
