SFP28-25G-BX-U-40KM-GM-BO BlueOptics BO04Q27640D Transceiver

High-Performance SFP28 25GbE BiDi Singlemode Transceiver for long-reach links with the SFP28-25G-BX-U-40KM-GM-BO

The SFP28-25G-BX-U-40KM-GM-BO is a 25GbE SFP28 pluggable optics module engineered for long-reach singlemode connectivity in space- and power-efficient network designs. By using BiDi BX-U transmission over a simplex LC interface, the SFP28-25G-BX-U-40KM-GM-BO enables 25G Ethernet transport with reduced fiber consumption while maintaining deterministic optical behavior across extended paths.

Architecturally, the SFP28-25G-BX-U-40KM-GM-BO aligns with modern switch and router platforms that provide SFP28 cages attached to high-throughput ASIC lanes, allowing dense 25GbE uplinks without chassis-level optical line cards. The 1270 nm optical design targets ZR-class long-reach topologies where link budgets, patch-field loss, and cross-connects must be accommodated without compromising port density. This makes the SFP28-25G-BX-U-40KM-GM-BO suitable for spine/leaf uplinks, data center interconnect edges, and metro point-to-point segments where operational simplicity and consistent interoperability are required.

Why Choose the SFP28-25G-BX-U-40KM-GM-BO?

The SFP28-25G-BX-U-40KM-GM-BO provides a practical density-to-reach profile for enterprise and service-provider networks that need 25GbE over singlemode at up to 40 km while optimizing fiber utilization through BiDi simplex cabling. It supports scalable rollouts by standardizing on an SFP28 form factor that fits high-port-count access, aggregation, and leaf tiers, simplifying sparing and reducing operational variance.

BlueOptics designs optics with a focus on predictable link performance, robust qualification, and alignment to contemporary data center and carrier operating models. The result is an enterprise-ready transceiver portfolio engineered for stable operation in mixed-vendor environments and structured cabling standards.

Key Applications:

• Data center interconnect (25GbE long-reach)
• Carrier and metro Ethernet point-to-point links
• Spine/leaf extended-reach uplinks
• Aggregation and access backhaul over SMF
