How are they connecting at each end.? Is it directly to a cabinet? This should determine your connections required.

Whats the distance? This will determine if its OS1 or OM2 or OM3. Depending a a campu size OM3 is normal. I'd use this over OM2 as it is upgradable in the future if you need 10 gig (I think), It been a while since i dealt with fibre. Your bends should be fine, but don't go fixing them at 90 degrees. Just let your cables be tidy but sit natturally.

Whats your Insertion and RL Budget? Are the connections 2.5mm or 1.25mm ferrule connections? This will determine your connector and cabling type. Good connectors will give you low loss. bad connectors will give you high loss.

You also have to consider the polishing specification. If its OM3 you can hand polish them and they'll work. If you chose OS1 you have to buy them in 'cos they have to be machine polished. If you need very low RL then you'll havr to buy APC connectors not just PC.....there are a lot of questions you haven't answered.!!

OK looking at what you typed.

OM3 MM cable which is upgradable and cheap. You still need to know your connection quantity.but lets say you are connecting one pc to a cabinet. One connection will work. Use one connection for each pc say.
