Module Guide
Note:
Depending on how light travels, optical fibers are divided into multi-mode optical fiber and single-mode
optical fiber.
Single-mode optical fiber has very thin core, and transmits only in single mode on a
given wavelength. It features wide band and large transmission capacity.
Multi-mode optical fiber allows transmission in multiple modes on a given wavelength.
In multi-mode, lights in different modes travel at different speeds, resulting in phase
distortion and thus limiting the transmission band. In terms of fiber core size, there
are two types of multi-mode optical fibers: 62.5 μm and 50 μm, the transmission
media accepted by the ISO/IEC 11801 standard.
