Chapter 4 Flexible Interface Cards (Router 6000)

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.
