SFP28-25G-BX-D-40KM-MT-BO BlueOptics BO04Q33640D Transceiver

High-Density 25GbE SFP28 BiDi Singlemode Optics for 40km Interconnects with the SFP28-25G-BX-D-40KM-MT-BO

The SFP28-25G-BX-D-40KM-MT-BO is a 25GbE SFP28 BiDi singlemode transceiver engineered for long-reach, single-fiber Ethernet links where switch and router optical ports must deliver predictable throughput and deterministic latency across metro distances. In leaf-spine architectures and data centre interconnect designs, it supports efficient uplinks from 25G Top-of-Rack domains into aggregation layers without increasing fiber counts.

By enabling LC-Simplex, single-fiber operation at 1310nm, the SFP28-25G-BX-D-40KM-MT-BO aligns with modern PCIe-centric server and storage platforms that depend on high east-west bandwidth to feed CPU- and GPU-accelerated workloads. Its ZR reach class supports 40km point-to-point links for resilient L2/L3 extensions, storage replication paths, and distributed compute, while maintaining compact SFP28 density for scalable port expansion and reduced rack-level power per bit.

Why Choose the SFP28-25G-BX-D-40KM-MT-BO?

The SFP28-25G-BX-D-40KM-MT-BO provides an architectural advantage when fibre scarcity, conduit constraints, or incremental upgrades require 25GbE capacity over a single strand, while preserving switch port density and simplifying patching. It enables consistent long-haul uplinks with enterprise-grade optics behaviour suitable for scale-out deployments and controlled change windows.

BlueOptics focuses on interoperability-oriented engineering and stable optical performance for production networks. The design approach emphasises reliable operation in dense switching environments and compatibility with established data centre cabling standards, supporting repeatable rollout procedures across multi-site infrastructures.

Key Applications:

• 25GbE data centre interconnect up to 40km
• Top-of-Rack to aggregation uplinks
• Metro Ethernet point-to-point links
• Leaf-spine fabric extensions over SMF
