This article will analyze key performance parameters such as transmission rate, wavelength, numerical aperture (NA), output power, and receive sensitivity of optical modules. It will also discuss how to choose suitable optical modules based on practical requirements. As an essential component of optical fiber communication, optical modules are optoelectronic devices that facilitate the conversion between optical and electrical signals during the transmission process. Understanding their key parameters isn't just technical jargon – it's critical for ensuring compatibility, performance, and reliability in your data center. The extinction ratio indicates the capability of an optical module to identify signal 0 and signal 1. The unit of the center wavelength is a nanometer (nm). The general center wavelengths are 850nm, 1310nm, and 1550nm, as well as 1270nm-1610nm. What are the common parameters of optical modules First, the central wavelength: unit nanometer (nm), there are currently three main types: 1) 850nm (MM, multi-mode, low cost but short transmission distance, generally only 500M can be transmitted); 2) 1310nm (SM, single mode, large loss but small.
