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. Optical modules are crucial for today's communication systems as they convert electrical signals into light signals for rapid data transfer. Understanding their key parameters isn't just technical jargon – it's critical for ensuring compatibility, performance, and reliability in your data center. This chapter describes how to configure the Optical Amplifier Module and Protection Switching Module (PSM). We'll cover everything from physical form factors to spectral characteristics, modulation formats. An optical transceiver module (optic module or simply a transceiver) is a device that integrates a transmitter and a receiver for transmitting and receiving optical signals over fiber optic cables.
