Fiber optic cables
Multimode OM3 and OM4 and singlemode OS2 assemblies, in LC, SC, ST and the MTP and MPO trunks that feed high density panels. We build patch cords for inside a cabinet and longer runs for the pull between closets.
28 units in this part of the catalog, $14.31 to $373.74.
Picking one of these
Fiber earns its place where copper runs out: long backbone links, runs between buildings, and paths where the two ends can sit at genuinely different potentials and a copper cable would become the thing that joins them. Mode and connector both have to match at each end, and a bend tighter than the jacket allows costs you signal quietly.
Not sure of the size
The load calculator adds up what you plan to plug in and leaves only the units rated to carry it with room to spare.
