How to read the optical module

If you know the model or type of an optical module, you can view the section "Pluggable Modules for Interfaces" in the Hardware Description to look up parameters of the optical module, including the center wavelength, transmission distance, fiber types supported, receive optical. When the optical module on an interface is faulty, you can run the display commands to view information about the optical module. ) ships with a small EEPROM that stores two kinds of information: a fixed Serial-ID block (vendor, part number, serial number, capabilities) and—when provided—a diagnostics area (real-time temperature, voltage, TX/RX power, etc. Today, ETU-LINK will introduce how to query the information of optical module on Huawei switch.

How to read the label on an optical module

Generally, the label of an optical module provides the following information: manufacturer, serial number, speed, center wavelength, mode (single-mode/multimode), and transmission distance. To determine if your SFP (Small Form-factor Pluggable) module is single mode or multimode, you can look for specific markings or labels on the module itself. Typically, single mode SFP modules are labeled as "SM" or "single mode," while multimode modules may be labeled as "MM" or "multimode. During use, reading optical module information helps understand its real-time operating status, enabling faster troubleshooting of link abnormalities.

How many ports does the optical module have

Used for BiDi (Bidirectional) modules where data is sent and received on the same strand using different wavelengths. An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. Think of it as the "translator" for your network equipment, converting electrical signals into optical signals. Both the GBIC module and SFP module are input/output devices used to link the 1000BASE-X fiber optical or copper network by plugging into a Gigabit Ethernet port of network switch or router devices. Switches come in three types: those with purely Ethernet ports, those with purely optical ports, and those with a combination of both.

Execute the following command to view detailed interface and optical module status: ethtool <devname> The output includes interface rate, module rate, link status (Link detected: yes is required for normal module operation), and interface configuration details. For optical modules used on switches, we read their information via brand-specific terminal commands.

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.

Single-mode and multi-mode optical module optical ports

Single-mode and multi-mode optical module optical ports

Single fiber modules (BiDi) use one fiber for both transmitting and receiving data. Single-mode fiber uses a 9/125 µm core/cladding structure that supports only one propagation mode, which minimizes modal dispersion and allows signals to travel tens of kilometers with low attenuation. The secret lies in fiber optic technology, and understanding the basics—1-core, 2-core, Single Mode (SM), and Multi-mode (MM)—is key to mastering this field. These components offer distinct characteristics and compatibilities that cater to different network requirements.
