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

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

The SFP28-25G-BX-U-40KM-IT-BO is a 25GbE SFP28 optical transceiver engineered for singlemode, single-fiber BiDi connectivity where switch and router platforms must scale port density without expanding fiber counts. In spine-leaf fabrics and routed aggregation layers, the SFP28-25G-BX-U-40KM-IT-BO enables deterministic point-to-point links up to 40 km using a compact SFP28 form factor and an LC-Simplex interface suitable for structured cabling and patching discipline.

Designed for modern 25G Ethernet NIC-to-switch and switch-to-switch paths, the SFP28-25G-BX-U-40KM-IT-BO supports clean integration into PCIe-based server I/O architectures by extending the reach of 25GbE uplinks from compute nodes, storage clusters, and edge aggregation without changing host bus or adapter design. The singlemode BiDi BX-U optics at 1270 nm optimize long-haul link budgets for metro and campus extensions, keeping latency and packet processing governed by the network ASIC rather than physical-layer workarounds.

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

The SFP28-25G-BX-U-40KM-IT-BO is selected when an enterprise needs long-reach 25GbE while preserving fiber capacity and port density. By using simplex singlemode for BiDi operation, it supports scalable expansion in access and aggregation designs, reduces cross-connect complexity, and aligns with operational requirements for reliable, standards-based optics across distributed sites.

BlueOptics focuses on interoperability-oriented engineering, consistent optical performance, and production controls suited to enterprise deployment. This approach supports repeatable rollout across mixed vendor switch estates and helps maintain predictable link behavior under data centre and metro environmental conditions.

Key Applications:

• Data center interconnect up to 40 km
• Campus and metro 25GbE uplinks
• Aggregation to core switch links
• Single-fiber BiDi expansion projects
