QSFP-100G-SWDM4-BO BlueOptics BO25LS856S1D Transceiver

High-Density QSFP28 100GbE SWDM4 Multimode Transceiver Module with the QSFP-100G-SWDM4-BO

The QSFP-100G-SWDM4-BO is a QSFP28 100GbE multimode optical transceiver engineered for Top-of-Rack uplinks and leaf/spine aggregation where predictable short-reach performance and port density are critical. Using SWDM4 over an LC duplex interface, the QSFP-100G-SWDM4-BO supports efficient break-in of 100GbE capacity into existing OM3/OM4 multimode plant within defined reach limits, reducing complexity in high-port-count switching tiers.

In modern switch architectures, the QSFP-100G-SWDM4-BO aligns with PCIe-attached compute and storage clusters by delivering deterministic 100GbE fabric connectivity between GPU and CPU nodes, NVMe-over-Fabrics gateways, and core services. Its SWDM4 optical approach consolidates multiple wavelengths onto multimode fibre to preserve front-panel density and simplify patching, while the 918 nm operating wavelength and short-reach design target low-latency intra-data-centre links where signal integrity and thermal stability drive uptime.

Why Choose the QSFP-100G-SWDM4-BO?

The QSFP-100G-SWDM4-BO is selected when you need 100GbE scale-out connectivity that fits standard QSFP28 switch ports and maintains a strong density-to-performance ratio without introducing single-mode operational overhead for short links. For enterprise deployments, the QSFP-100G-SWDM4-BO enables repeatable leaf/spine expansion, consistent optics qualification across switch fleets, and reliable multimode interconnects for aggregation and inter-rack trunks.

BlueOptics designs optics for stable operation in enterprise data centres, focusing on standards-aligned interoperability, controlled manufacturing processes, and compliance requirements such as CE, FCC, and RoHS to support regulated environments and long-term platform lifecycle management.

Key Applications:

• Top-of-Rack to leaf/spine 100GbE uplinks
• 100GbE switch aggregation and core uplinks
• Intra-data-centre multimode interconnects (OM3/OM4)
• High-density 100GbE fabric expansion
