Optical modules are classified by transmission distance
Optical modules are classified by package type, rate, laser type, center wavelength, mode, connector type, modulation format, transmission distance, interface operation mode, and pluggability. These classifications determine compatibility, performance, and application. Optical Modules are categorized by their reach capabilities: Note: CWDM/DWDM modules enable longer distances through wavelength division multiplexing. Allows multiple signals to be transmitted simultaneously over a single fiber: CWDM (Coarse Wavelength Division Multiplexing): Uses wider wavelength. Optical fibers are classified into single-mode fibers and multi-mode fibers. Among them, long-distance optical modules refer to optical modules with a transmission. An optical module usually consists of an optical transmitting device (TOSA, including a laser), an optical receiving device (ROSA, including a photodetector), functional circuits,main control circuit board (PCBA), housing and optical (electrical) interface and other components. These modules are typically installed in Optical Line Terminals (OLTs) at the service provider's central office and Optical Network Units (ONUs) or Optical Network. First of all, we can classify optical modules into several categories, which are FC Fibre Channel Optical Module (which is mainly used in storage area network), Ethernet Optical Module, that is, we usually contact with grey optical module (ordinary optical module) and colour optical module (WDM). -
