Huawei RRU equipment single-core optical module

Huawei RRU single-core optical modules are SFP/Bidi modules designed for high-speed optical transmission between RRUs and BBUs, supporting cost-effective, long-distance wireless network deployment.OverviewHuawei Remote Radio Units (RRUs) convert digital baseband signals into RF signals for transmission over wireless networks. To connect RRUs to Baseband Units (BBUs), single-core optical modules (also called Bidi SFP modules) are used, enabling bidirectional data transmission over a single optical fiber, which reduces cabling complexity and installation costs (Alibaba) .Key FeaturesType: SFP (Small Form-factor Pluggable) Bidi optical moduleTransmission: Single-core fiber, supporting bidirectional communicationData Rate: Typically 25G or compatible with the RRU model's interfaceCompatibility: Works with Huawei RRU models such as RRU5905, RRU5909, and other 2T2R or 4T4R units (Alibaba) Power and Environment: Designed for outdoor deployment, IP65-rated, and energy-efficient to match RRU power amplifiers (Huaxun Telecom) Cost and Availability: Modules are available for wholesale or bulk purchase, with prices starting around $7 per unit (Alibaba) AdvantagesReduced Fiber Usage: Single-core Bidi modules allow both transmit and receive signals on one fiber, halving fiber requirements.Simplified Installation: Easier deployment in dense urban or remote areas where fiber availability is limited.High Reliability: Designed to withstand harsh environmental conditions, ensuring stable RF signal transmission.Flexible Network Design: Supports multiple frequency bands and can be integrated into 3G, 4G/LTE, and 5G networks (Huaxun Telecom) .ConsiderationsDistance Limitations: Single-core Bidi modules have specific maximum transmission distances depending on wavelength and fiber type.Compatibility Check: Ensure the module matches the RRU model and BBU interface to avoid signal loss or incompatibility.Spare Parts and Maintenance: Huawei EOL (End-of-Life) parts are available through resellers for replacement or network expansion (JEMSdata) .ConclusionHuawei RRU single-core optical modules are essential for efficient, cost-effective optical connections in wireless networks. They provide bidirectional transmission over a single fiber, support multiple RRU models, and are suitable for both 4G and 5G deployments, offering high reliability and simplified installation in diverse network environments.
