The optical module is labeled with its transmission wavelength
, 850nm, 1310nm, 1550nm), as well as the fiber type (SMF or MMF) and transmission distance. The core technical parameters of optical modules include: transmission rate, encapsulation, transmit optical power, receive sensitivity, transmission distance, center wavelength, optical interface type, operating temperature, maximum power consumption, etc. Matching the correct wavelength with the right fiber type and application is essential to ensure: The most commonly used SFP optical modules operate at 850nm, 1310nm, 1490nm, and 1550nm. One of the most effective and widely used methods is through the pull-tab color on transceiver modules. The transmitting interface inputs electrical signals of a certain bit rate, which are then processed by internal driver chips. The ring color of the optical transceivers are colorful, different colors corresponding to different wavelength.
