It supports both single-mode and multi-mode fiber cables and is capable of operating across a wide range of data. The ethtool command enables you to query or control the network driver and hardware settings. The Cisco Small Business Series Switches allow you to plug in a Small Form-factor Pluggable (SFP) transceiver in their optical modules to connect fiber optic cables. DDM (Digital Diagnostics Monitoring) is a feature that is included in optical modules, such as SFP, SFP+, QSFP, and QSFP+ transceivers.
