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

High-Density 25GbE SFP28 BiDi Singlemode Transceiver for Long-Reach Links with the SFP28-25G-BX-U-40KM-VA-BO

SFP28-25G-BX-U-40KM-VA-BO is a BlueOptics SFP28 25GbE BiDi singlemode transceiver engineered for 40km ZR-class reach over LC simplex fiber, enabling compact 25G Ethernet optical handoffs where port density and link budget are critical. It integrates cleanly into modern leaf-spine fabrics built on current-generation switch ASICs and NIC platforms, providing deterministic 25GbE lane operation in a pluggable form factor without consuming additional fiber pairs.

Designed for PCIe-driven server and storage endpoints as well as ToR uplinks, SFP28-25G-BX-U-40KM-VA-BO supports high-throughput east-west and north-south traffic patterns where predictable latency and low retransmission rates matter. In architectures combining CPU-centric virtualization with GPU-backed AI/HPC nodes, it helps sustain steady fabric utilization by extending 25GbE connectivity to remote rows, meet-me rooms, or metro aggregation points, while preserving rack-level expansion flexibility through standard SFP28 cages and switch uplink modules.

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

SFP28-25G-BX-U-40KM-VA-BO delivers a pragmatic density-to-reach profile for enterprises standardizing on 25GbE while needing long singlemode spans, simplifying cabling with BiDi LC simplex and reducing operational complexity in constrained pathways. Its ZR-class reach supports scalable growth from ToR to distribution and inter-building links, aligning with redundant fabric designs and predictable service turn-up.

BlueOptics focuses on interoperable optics engineered for enterprise reliability, emphasizing consistent optical performance, controlled manufacturing, and compatibility with contemporary data center standards for pluggable Ethernet transceivers. SFP28-25G-BX-U-40KM-VA-BO reflects this approach by targeting stable 25G ETH transport over long-reach singlemode infrastructure.

Key Applications:

• Data center interconnect over singlemode
• Top-of-rack uplink to aggregation
• Carrier and Metro Ethernet handoff
