This document explains how to install and operate the Cisco NCS 2000 Series passive optical modules, the fiber shuffle, and the MPO fan-out unit. The passive optical modules are used to build the. Small Form-factor Pluggable modules (SFP module) are the workhorses of modern network connectivity, enabling flexible fiber optic or copper links between switches, routers, firewalls, and servers. Optical modules and connected fibers emit laser radiation that can cause eye damage. The device must use optical or copper modules recommended on the configurator because non-Huawei-certified optical or copper modules cannot ensure transmission reliability and may affect service stability. Common types of optical modules include SFP, SFP+, SFP28, QSFP, QSFP28, etc. They enable high-speed connections between active equipment and allow system scalability without the need for full infrastructure replacement.
