How Do I Identify Different Fibers from Their Appearances?

How Do I Identify Different Fibers from Their Appearances?

Optical fibers are classified into multimode and single-mode optical fibers:
  • Multimode optical fibers can be used with multimode optical modules to implement low-cost, short-distance transmission. Multimode optical fibers are classified into OM1, OM2, OM3, and OM4 types. OM1 and OM2 optical fibers are usually orange, whereas OM3 and OM4 optical fibers are usually light green. For specifications of various optical fibers, see the text printed on optical fibers.
  • Single-mode optical fibers, usually G.652 fibers, can be used with single-mode optical modules to implement long-distance transmission. Single-mode optical fibers are yellow.
