The US Transceivers compatible 845966-B21 is a 100GBASE-SR4 QSFP28 optical transceiver module designed as a high-performance, cost-effective alternative for use in HP-compatible networking environments. Built in the compact QSFP28 form factor, this module delivers 100Gbps aggregate data throughput across four parallel 25Gbps lanes over multimode fiber, supporting link distances up to 100 meters on OM4 fiber.
This transceiver operates at an 850nm wavelength and uses an MPO/MTP connector interface, making it well suited for high-density data center deployments and short-reach parallel optical interconnects. The module supports Digital Diagnostic Monitoring (DDM/DOM), enabling real-time visibility into key performance parameters such as temperature, voltage, and optical power levels.
The US Transceivers compatible 845966-B21 is TAA compliant and meets RoHS, CE, and REACH regulatory standards, as well as IEEE 802.3bm and QSFP28 MSA specifications, ensuring reliable interoperability in enterprise and cloud networking infrastructures.
