Typically when dealing with fiber connections you will have either an LC or SC cable that will go over a patch panel and terminate on both sides on a switch with a transiever module such as the MGBSX1 transiever commonly used on Cisco switches.
Two main types single mode and multimode:
Single Mode - Offers less bandwidth, although can transmit further distances (around 5KM maximum)
Multimode - Offers more bandwdith but at a reduced maximum distance (between 300 - 600 meters approx)
Two common connector types:
SC - 1.25mm in diameter
LC - Older 2.5mm in diameter
Typically as good practise the transit cables (the casbles connecting the two patch panels together) should be straight through (e.g. Fiber 1 on Patch Panel A should be Fiber 1 on Patch Panel B and so on)
One of the patch cables should be Fiber 1 = A and Fiber 2 = B. The other patch cable on the other site should be crossed e.g. Fiber 1 = B and Fiber 2 = A.
** The fibers must be crossed at one end for a connection to be established on the switches. **
