Huawei Single-Core Optical Module

Huawei Single-Core Optical Modules are certified single-mode transceivers designed for reliable data transmission over a single fiber, supporting various network applications with Huawei switches.OverviewHuawei Single-Core Optical Modules, also known as single-fiber bidirectional (BiDi) modules, transmit and receive data over a single optical fiber, using different wavelengths for upstream and downstream communication. These modules are commonly used in access networks, ring networks, storage networks, and long-haul networks, providing a compact, plug-and-play solution for flexible deployment .Types and InterfacesHuawei offers a range of optical modules compatible with different interfaces:SFP (Small Form-Factor Pluggable): Standard modules for 1G or 100M transmission, often used in enterprise switches .SFP+: Enhanced SFP modules supporting 10G transmission rates.XFP: 10G modules with LC connectors, larger than SFP+.SFP28: Supports 25G transmission, compatible with SFP+ interface size.QSFP+ / QSFP28: High-speed modules for 40G and 100G networks, using MPO connectors . Single-core modules are typically SFP or SFP+ form factors, optimized for single-mode fiber deployment.Certification and CompatibilityHuawei emphasizes the use of certified optical modules to ensure network reliability. Certified modules are labeled with "HUAWEI" and can be verified using commands such as display transceiver or display elabel on Huawei switches. Modules delivered after January 1, 2016, should have a manufactured date later than 2016-01-01 and a software version of V200R008 or later to be considered certified . Using non-certified modules may result in unstable connections or service disruptions.Key FeaturesSingle-fiber bidirectional communication reduces cabling requirements.Plug-and-play installation for quick deployment.Monitoring capabilities (for eSFP modules) include voltage, temperature, bias current, and optical power levels.Wide application in access, ring, storage, and long-haul networks .Usage ConsiderationsEnsure the module is certified by Huawei to avoid link instability.Single-core modules require matching wavelengths at both ends of the fiber.Attenuators may be needed for short-distance connections to prevent high receive power damage .Multi-mode fibers are generally not compatible with single-mode single-core modules . Huawei Single-Core Optical Modules provide a reliable, space-efficient solution for modern network infrastructures, particularly where fiber resources are limited or bidirectional communication is required.
