The optical module market is evolving from a "basic communication component" to a "core infrastructure component for AI computing power." Its prospects are deeply intertwined with the global process of digitalization and intelligentization. The 25G SFP28 LR optical module is a core component of next-generation network connectivity, designed to meet the needs of 5G midhaul, modern data center leaf-spine architectures, and high-speed enterprise networks. This module provides a data rate of 25.78 Gbps, achieving reliable transmission over distances of up to 10 kilometers via single-mode fiber, and operates at a wavelength of 1310nm. Fully compliant with IEEE 802.3by and SFP28 MSA standards, its superior performance and energy efficiency make it a cost-effective choice for a smooth upgrade from 10G to 100G network architectures.
Product Model: SFP28-25G-LR-1310
Core Value: Provides a high-density, low-latency, and low-cost-per-bit backbone connectivity solution for 5G networks and cloud data centers.

Why is 25G SFP28 the optimal choice for operator access networks?
Data Center Standard Shift: Cloud computing has established "25G server access -> 100G uplink" as the standard for the next-generation leaf-spine architecture. All newly built and expanded cloud data centers are adopting 25G, an irreversible trend.
Optimal Cost-Effectiveness: 25G SerDes (serializers/deserializers) are currently the "sweet spot" for silicon chips, offering optimal energy efficiency and cost. Bundling four 25G channels into 100G is more economical than bundling 10G channels.
5G Network Construction: 25G optical modules are widely used in the midhaul of 5G transport networks, representing a stable and growing market for several years.
Smooth Evolution Path: The 25G physical layer is compatible with 10G, allowing for the reuse of fiber optic infrastructure and lowering the upgrade threshold.
