2-6 Fiber Cable
An optical cable is a transmission cable made to transmit the converted laser signal to a long
distance and uses two transmission modes.
Single Mode
: It is used for broadband and long-distance transmission with a core diameter of
9 ㎛, and it is possible to transmit without relay up to about 50Km. In the case of
single-mode with a small core diameter, it is difficult to transmit a large amount of
information because the cable passage is narrow, but instead it can be transmitted
over a long distance. The cable color is mainly yellow.
Multi Mode
: The core diameter is 50~100 ㎛, so it is often used in short distances. In the case
of multimode with a large core diameter, a large amount of information can be
transmitted because the passage of the cable is wide, and the color of the cable is
mainly orange.
Optical connectors include LC, ST, MTRJ, SC, FC, and MU types, but EMB-OPT02 mainly uses
multimode LC type as shown in [Figure 2-7].
