Fiber patch cord at different transmission mediacan be classified ascommon silicon-based optical fiber single-mode, multimode patch cord, there areother transmission media such as plastics and other fiber patch cord; Accordingto the connector, the patch cord can be classified as FC patch cord, SC patchcord, ST patch cord, LC patch cord, MTRJ patch cord, MPO patch cord, MU patchcord, SMA patch cord, FDDI patch cord, E2000 patch cord DIN4 patch cord, D4patch cord, etc. Common ones are FC-FC、FC-SC、FC-LC、FC-ST、SC-SCand SC-ST patch cord, etc

Single-mode Fiber：Universally, fiber patch cord indicated by yellowcolor, connector and protective sleeve blue; longer transmission distance.

Multi-mode Fiber：Generally orange, some with gray, connector andprotection applied beige or black; transmission distance is shorter.
