1310nm 25G SFP28 10km Optical Module: Energy-Efficient, Standard-Compliant Solution for Short-Distance High-Speed Networ

In today’s data-driven landscape, short-distance high-speed connectivity—whether within data centers, enterprise campuses, or local telecom hubs—demands reliability, compatibility, and efficiency. The 1310nm 25G SFP28 10km Optical Module (also known as SFP-25G-LR) rises to this challenge, combining industry-leading standards compliance, low power consumption, and easy installation to become the go-to choice for businesses upgrading their short-haul network infrastructure.

At the heart of this module is its ability to deliver consistent, high-speed data transmission. It supports a 25 Gbps data rate—ideal for handling bandwidth-heavy tasks like real-time data processing, cloud storage access, and high-definition video streaming that define modern business operations. Paired with a 1310nm wavelength and optimized for single-mode fiber (SMF), it ensures reliable connectivity over 10 kilometers—the sweet spot for short-distance links such as data center rack-to-rack connections, enterprise building-to-building networks, or local telecom distribution.

What sets it apart is its use of high-quality optical components: either VCSEL/PIN (Vertical-Cavity Surface-Emitting Laser/Positive-Intrinsic-Negative Photodiode) or APD (Avalanche Photodiode) technology. These components minimize signal loss, reduce interference, and maintain stable data integrity even at maximum reach, ensuring uninterrupted performance for mission-critical applications.

For IT teams and network administrators, compatibility with existing equipment is make-or-break—and this module delivers. It is fully CISCO COMPATIBLE, a gold standard in networking that guarantees seamless integration with Cisco switches, routers, and servers. Beyond Cisco, its adherence to industry-wide SFP28 specifications means it works effortlessly with networking gear from other leading brands (such as HPE, Juniper, and Dell), eliminating the need for proprietary hardware and simplifying mixed-vendor network upgrades.

Adding to its versatility is the LC connector—the most widely used standard in optical networking. LC connectors are compact, easy to mate, and provide a secure, low-loss connection to single-mode fiber cables. This not only speeds up installation but also ensures long-term reliability, as LC connectors are resistant to wear and tear from repeated use.

In an era where sustainability and cost savings are top priorities, the module’s 1.5W power consumption stands out as a key advantage. Compared to older, less efficient modules that can consume 2W or more, this low-power design reduces energy bills—especially critical for data centers or enterprises with hundreds of modules in operation. It also generates less heat, lowering the load on cooling systems and extending the lifespan of surrounding network equipment, further reducing long-term operational expenses.

This energy efficiency doesn’t come at the cost of performance. The module maintains its 25Gbps speed and 10km reach while staying within the 1.5W power budget, making it a “green" choice for businesses looking to reduce their carbon footprint without compromising network performance.

Networks don’t exist in perfect conditions—and this module is built to handle real-world environments. It supports an operating temperature range of 0°C to 70°C, making it suitable for deployment in climate-controlled data centers, semi-outdoor telecom cabinets, or enterprise server rooms. Whether facing summer heatwaves or winter cold snaps, the module maintains consistent performance, eliminating the need for expensive temperature-regulating equipment and ensuring uptime even in challenging conditions.

For businesses operating in global markets, regulatory compliance is non-negotiable. The 25G SFP28 10km Optical Module is RoHS Compliant, meaning it is free from hazardous substances such as lead, mercury, and cadmium. This not only meets strict environmental regulations in the EU, North America, and beyond but also aligns with corporate sustainability goals. Choosing RoHS-compliant products reduces environmental impact during manufacturing, use, and disposal—making this module a responsible choice for forward-thinking businesses.

This module’s combination of speed, reach, and compatibility makes it versatile across key sectors:

• Data Centers: Connects server racks, storage arrays, and top-of-rack (ToR) switches, enabling fast data transfer for cloud services and big data analytics.
• Enterprises: Links multiple office buildings on a campus (up to 10km apart), supporting seamless collaboration tools, video conferencing, and shared access to centralized databases.
• Local Telecom: Powers short-haul distribution networks, delivering high-speed internet and TV services to residential or commercial areas.
