Where are Huawei optical modules installed

Fiber and communications infrastructure knowledge brief Published 13 May 2024

Prepared for preliminary research by the ROGER FIBRE knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Huawei optical modules are installed in the optical interfaces of switches, routers, and other network devices, and can be accessed via specific device ports or slots.

Physical Placement in Devices

Huawei optical modules are plugged into designated optical interfaces on networking equipment such as S series switches, routers, and high-speed network cards. These modules are hot-swappable, meaning they can be inserted or removed without powering down the device. Depending on the module type, they fit into different form factors: SFP/eSFP: Small form-factor pluggable modules, typically supporting LC fiber connectors.

SFP+ and SFP28: Enhanced versions for higher transmission rates (10GE, 25GE) with the same interface size as SFP.

XF

P: 10 Gigabit modules, larger than SFP+. QSFP+ and QSFP28: Quad small form-factor pluggable modules for 40GE and 100GE, supporting MPO fiber connectors.

CF

P: Centum form-factor pluggable modules for high-speed data communication, larger than QSFP28. Each module is inserted into a specific port or slot on the device, and the device's interface type and number determine the exact location.

Identifying and Accessing Modules

Huawei devices provide commands to view and monitor optical modules:display transceiver interface: Shows module type, vendor, wavelength, and diagnostic information.display interface brief: Lists all ports and their connected modules.display elabel and display version: Verify if the module is Huawei-certified. These commands allow network administrators to locate modules physically and check their operational status, including temperature, voltage, and optical power.

Manufacturing and Certification

Huawei optical modules may be manufactured by Huawei or third-party vendors. Certified modules carry the HUAWEI label and meet strict quality and compatibility standards. Non-certified modules may cause installation or operational issues due to nonstandard sizes or data bus defects.

High-speed modules like 40GE and 100GE have been certified by Huawei since 2016.

Summary

In essence, Huawei optical modules are located in the optical ports or slots of Huawei networking devices, with their exact position determined by the interface type and slot number. They can be monitored and managed using Huawei commands, and certified modules ensure proper functionality and compatibility within the network.
