High-Density 10GbE XFP SR Multimode Optical Transceiver Module with the 443756-B21-BO
The 443756-B21-BO is a 10GbE Ethernet optical transceiver in XFP form factor, engineered for short-reach multimode fiber deployments where deterministic link behavior and predictable interoperability are required. As an SR optics module operating at 850nm, it is optimized for low-latency switching fabrics, server access layers, and consolidation uplinks that still rely on XFP ports.
In access and aggregation designs, the 443756-B21-BO supports clean 10GbE signaling over MMF up to 300m, enabling efficient top-of-rack to end-of-row cross-connects and campus/IDF interconnects without overprovisioning long-reach optics. The LC duplex interface standardizes patching and simplifies structured cabling, while the XFP electrical interface allows straightforward integration into established 10GbE platforms and line cards, preserving PCIe and host resources by terminating the network link at the switch or NIC port rather than the compute node.
Why Choose the 443756-B21-BO?
The 443756-B21-BO delivers a practical density-to-performance fit for environments maintaining XFP-based 10GbE estates, keeping optics consistent across spares and change windows. It supports scalable rollout patterns for switch uplinks and inter-switch links, helping reduce operational variance by using a single SR multimode optic class for short-reach segments.
BlueOptics designs compatibility-focused transceiver modules with an emphasis on stable link negotiation and data center-aligned compliance. The 443756-B21-BO follows modern environmental and regulatory expectations with CE, FCC, and RoHS conformity, supporting controlled deployment in enterprise and institutional infrastructures.
Key Applications:
- 10GbE data center switching uplinks
- Inter-switch cross-connects (SR MMF)
- Campus and IDF short-reach fiber links
- Server access connectivity with XFP ports
