In many cases, the baud rate of the optical interface does not equal the baud rate of the electrical interface. In these cases, a gearbox is used within the module to convert between the two rates.
Fundamentals of an Optical Module As an important part of fiber-optic communication, an optical module is a photoelectric converter which converts electrical signals into optical signals and vice versa. An
Driver chips and limiting amplifiers generally support multiple rates from 155Mb/s to 2.67Gb/s. Different rates, different transmission distances of
Depending on transmission rates, optical modules are classified into 100GE, 40GE, 25GE, 10GE, FE, and GE optical modules. The higher transmission rate an optical module provides,
Classification of Optical Module: Distinguished according to function, package form, transmission rate, wavelength, interface type, operating temperature and transmission distance.
