Huawei optical module SFP model

Huawei SFP optical modules are transceivers used in network devices to enable fiber or copper connectivity, available in various speeds, wavelengths, and distances.OverviewHuawei SFP (Small Form-factor Pluggable) optical modules are hot-swappable transceivers that allow switches, routers, and other network devices to connect via fiber or copper cables. They support multiple speeds including 1G, 10G, 25G, and higher, and are available in both standard and bidirectional (BIDI) configurations .Types and Specifications1G SFP Modules: Include FX (2 km), SX (550 m), LX (10–80 km), ZX (120 km), and copper options. CWDM and bidirectional SFPs are available for metro and access networks .10G SFP+ Modules: Include SR (300 m), LR (10 km), ER (40 km), ZR (80 km), and BIDI options for single-fiber links. BIDI modules must be used in pairs, e.g., SFP-10G-BXD1 with SFP-10G-BXU1 . CWDM and tunable DWDM SFP+ modules are available for metro WDM networks.25G SFP28 Modules: Include SR (100 m) and LR (10 km) options, with bidirectional single-fiber variants for data center switches .Other Modules: 8G/16G FC modules, XFP modules, and low-latency DAC/AOC cables for high-performance applications .Wavelengths and Transmission DistancesHuawei SFP modules operate at various wavelengths depending on the type:Standard SFP/SFP+: 850 nm (SR), 1310 nm (LR), 1550 nm (ER/ZR)BIDI SFP: Single-fiber modules use paired wavelengths, e.g., 1270 nm and 1330 nm for 10G BIDI modules . Transmission distances range from 300 meters to 120 km, depending on module type, fiber quality, and network design .Compatibility and SourcingHuawei SFP modules are compatible with Huawei switches, routers, and OLT systems. Compatible third-party transceivers are also available, offering cost-effective alternatives while meeting reliability and performance standards . Genuine Huawei modules can be purchased from authorized distributors and online suppliers, often with datasheets available for reference .Key ConsiderationsBIDI modules must be paired correctly to function.Check wavelength and distance specifications to ensure proper connectivity.Use genuine or certified compatible modules to avoid network issues.Hot-swappable design allows easy replacement without powering down devices. Huawei SFP optical modules provide flexible, high-performance connectivity for enterprise, metro, and data center networks, supporting a wide range of speeds, distances, and fiber types .
