The UCS-SFP-1WSR-C is a Cisco UCS–compatible SFP+ optical transceiver supporting 10 Gigabit Ethernet over multimode fiber at 850 nm wavelength.
This transceiver is compatible with Cisco UCS C-Series and B-Series servers, Nexus and MDS switches, Fabric Interconnects, as well as third-party SFP+ ports that accept Cisco-style optics.
It supports a line rate of 10 Gbps full-duplex, meeting IEEE 802.3ae 10GBASE-SR specifications.
This module delivers up to 300 meters over OM3 multimode fiber and up to 400 meters over OM4 multimode fiber using duplex LC connectors.
It uses an 850 nm vertical-cavity surface-emitting laser (VCSEL) optimized for short-reach Ethernet links.
UCS-SFP-1WSR-C requires duplex multimode fiber (OM3/OM4) terminated with LC connectors.
Yes, it is fully hot-swappable and can be inserted or removed from any compatible SFP+ slot without powering down the device.
Yes, it offers SFF-8472–compliant Digital Diagnostics Monitoring (DDM) for real-time tracking of optical power, temperature, voltage, and more.
It meets IEEE 802.3ae 10GBASE-SR, SFF-8431 electrical specifications, and SFF-8432 package and management interface standards.
The transceiver is rated for industrial operation from 0 °C to 70 °C ambient.
Align the LC connector, slide the module into the SFP+ slot until the latch clicks, then verify the link LED on your switch or server turns solid.
It includes a one-year limited warranty covering manufacturing defects and guaranteed compatibility with Cisco UCS platforms.
It is a fully tested third-party compatible optic designed to meet Cisco’s hardware and firmware requirements.
Verify fiber cleanliness, confirm correct OM3/OM4 cable type and LC terminations, check DDM readings for power levels, and ensure both ends negotiate at 10 Gbps.
