Fueled by the explosive growth of 5G, cloud computing, and digital transformation, the demand for high-performance, long-distance optical connectivity has never been greater. Velolan Networks, a leader in optical communication technology, addresses this need with its cutting-edge 25G SFP28 ZR 80km Dual-Fiber and 25G SFP28 BiDi ZR 80km Single-Fiber optical modules. These solutions offer unmatched 80km reach and flexible deployment options, making them ideal for Data Center Interconnects (DCI), Metropolitan Area Networks (MAN), and critical 5G fronthaul applications.
Unlocking Value: Dual-Fiber vs. BiDi Advantages
1. 25G SFP28 ZR 80km Dual-Fiber Module:
High Speed & Ultra-Low Latency: Delivers 25.78 Gb/s line rate with microsecond-level transmission latency achieved through optimized signal processing, essential for real-time data center operations and financial transactions.
Industry-Leading 80km Reach: Leverages high-performance EML lasers and SOA optical amplifiers over standard G.652.D single-mode fiber, enabling robust connections across vast metropolitan or regional distances.
Industrial-Grade Resilience: Operates flawlessly across an extreme temperature range (-40°C to +85°C), ensuring reliability in harsh outdoor or industrial environments. Hot-swappable design simplifies maintenance.
2. 25G SFP28 BiDi ZR 80km Single-Fiber Module:
Revolutionary Fiber Efficiency: Utilizes Wavelength Division Multiplexing (WDM) technology (Tx: 1295nm / Rx: 1309nm or Tx: 1309nm / Rx: 1295nm) to achieve bidirectional communication over a single fiber strand. Slashes fiber requirements by 50%, significantly reducing cabling costs and complexity.
Optimized Power Efficiency: Engineered for low power consumption (< 2.2W typical commercial, < 2.8W industrial), balancing high performance with energy savings and reduced operational expenditure (OPEX).
Space-Saving Deployment: Features a simplex LC connector, perfectly suited for scenarios with limited fiber availability, such as dense urban 5G cell site aggregation or legacy network upgrades.
Validated Innovation & Technological Leadership
Velolan's 25G SFP28 80km Dual-Fiber and BiDi technology represents a significant breakthrough. The core technology has successfully passed China's rigorous national-level scientific and technological achievement evaluation for "Optical Module Key Technology R&D," earning the prestigious designation of "Domestically Leading." This independent validation underscores Velolan's commitment to innovation and provides a solid foundation for the large-scale deployment of high-performance 5G networks globally.
Key Application Scenarios: Driving Digital Transformation
5G Fronthaul: The BiDi module is a game-changer, enabling cost-effective single-fiber connections between remote radio units (RRUs) and centralized baseband units (BBUs) over 80km, solving fiber scarcity and enabling flexible Centralized RAN (C-RAN) architectures.
Data Center Interconnect (DCI): The Dual-Fiber module ensures high-speed, low-latency synchronization of data across campuses or between data centers up to 80km apart, critical for disaster recovery, cloud service delivery, and content distribution.
Smart Cities & Industrial IoT: Dual-Fiber modules provide robust backbone connectivity for critical private networks (power grid monitoring, traffic management). BiDi modules enable efficient networking in dense smart device environments (industrial automation, surveillance systems).
