Understanding 155M SFP Transceivers: BIDI and Duplex Solutions

Introduction to 155M SFPs Optical transceivers play a crucial role in modern telecommunications and data networks. Among the widely used options, 155M SFPs—often referred to as OC-3 or STM-1 transceivers—are a standard for low to medium-speed optical communications. These transceivers are used in applications such as SONET (Synchronous Optical Network), SDH (Synchronous Digital Hierarchy), and […]
