Thorlabs' FC/PC patch cables are built with standard 62.5 μm / 125 μm Graded-Index Fiber (GIF625). Graded-index fiber provides significantly less bend loss than traditional multimode fibers.

Each patch cable includes two protective caps that shield the ferrule ends from dust and other hazards. Additional CAPF Fiber Caps for FC/PC-terminated ends are also sold separately.
