25G SFP28 SMF BIDI Optical Module: Reliable 20Km High-Speed Data Transmission for Modern Networks​

In an era where seamless long-distance data transfer is critical for data centers, enterprises, and telecom networks, the launch of the 25G SFP28 SMF BIDI Optical Module marks a significant leap forward. Engineered to deliver stable 25Gbps connectivity over 20 kilometers, this module combines advanced technology, easy installation, and broad environmental adaptability—making it the ideal choice for businesses scaling their high-speed network infrastructure.

At its core, the 25G SFP28 BIDI Optical Module is built for speed and reach. It supports a 25 Gbps data rate, ensuring lightning-fast transfer of large datasets, high-definition video streams, and cloud-based applications—critical for industries where latency and bandwidth bottlenecks can disrupt operations. What sets it apart is its ability to maintain reliable data transmission over 20 kilometers via single-mode fiber (SMF), eliminating the need for costly signal repeaters or shorter-range alternatives.

Complementing its speed and reach is its optimized wavelength configuration: 1270nm for transmission (Tx) and 1330nm for reception (Rx). This BIDI (Bi-Directional) design uses a single fiber strand for both sending and receiving data, reducing fiber cabling costs and simplifying network layout—especially valuable for long-haul links in telecom networks or campus-wide enterprise setups.

Consistent performance starts with reliable power and signal integrity. The module operates on a 3.3V power supply, a standard voltage that integrates seamlessly with most network devices, avoiding compatibility issues with existing power infrastructure. Its average output power of 0~6dBm ensures strong signal strength over the full 20km distance, minimizing data loss and errors even in challenging network conditions.

Additionally, the module boasts an extinction ratio of 3.5dB—a key metric for signal quality. This ratio ensures clear differentiation between "1" and "0" signals, reducing interference and maintaining data accuracy, which is essential for mission-critical applications like financial transactions, healthcare records, and real-time industrial monitoring.

For IT teams and network administrators, ease of deployment is a top priority—and this module delivers. It features the industry-standard SFP28 form factor, a compact design that fits into most switches, routers, and servers with SFP28 ports. There’s no need for specialized tools or complex hardware modifications; simply insert the module, and it’s ready to integrate with your network.

The Simplex LC interface further simplifies installation. LC connectors are small, durable, and easy to mate, ensuring a secure connection to single-mode fiber cables. This interface is widely used in data centers and telecom networks, making the module compatible with existing cabling systems and reducing the time and cost of network upgrades.

Networks operate in diverse environments, from climate-controlled data centers to semi-outdoor telecom cabinets—and this module is built to withstand them all. It supports an operating temperature range of 0°C to 70°C, making it suitable for indoor deployments like enterprise server rooms and data centers, as well as mild outdoor or industrial settings.

This temperature resilience ensures consistent performance year-round, even during seasonal temperature fluctuations or equipment heat buildup. For businesses operating in regions with moderate climates, this eliminates the need for expensive cooling solutions or temperature-controlled enclosures, lowering overall operational costs.

The 25G SFP28 SMF BIDI Optical Module is designed to meet the unique needs of three key sectors:

• Data Centers: Supports high-speed connectivity between server racks, storage systems, and top-of-rack (ToR) switches, enabling efficient data processing and cloud service delivery.
• Enterprise Networks: Connects multiple office locations or campus buildings over long distances, facilitating seamless collaboration, video conferencing, and shared access to centralized databases.
• Telecommunications Networks: Delivers reliable 25Gbps links for 5G backhaul, fiber-to-the-home (FTTH) expansions, and long-haul data transmission between telecom towers and core networks.

In a market where network demands evolve rapidly, future-proofing is essential. This 25G SFP28 module not only meets today’s 25Gbps requirements but also provides a pathway to scaling as bandwidth needs grow. Its compatibility with existing SMF infrastructure means businesses don’t have to replace their fiber cables—a major cost savings compared to upgrading to newer fiber types.
