What are the three kinds of fiber-optic lamps?

Single-mode and multimode optical fiber jumpers, and other optical fiber jumpers with plastic as transmission medium; According to the connector structure, it can be divided into FC jumper, SC jumper, ST jumper, LC jumper, MTRJ jumper, MPO jumper, MU jumper, SMA jumper, FDDI jumper, E2000 jumper, DIN4 jumper and D4 jumper. Common optical fiber jumpers can also be divided into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST and so on. Single-mode optical fiber: generally, optical fiber jumpers are represented by yellow, and connectors and protection are represented by blue; Long transmission distance. Multimode optical fiber: Generally, optical fiber jumpers are indicated by orange, and some are indicated by gray. Connectors and protective devices shall be beige or black. The transmission distance is short.
