HPE C8R24B

16 Gb Short-Wave Fibre Channel SFP+ Transceiver module

The HPE C8R24B is a 16 Gb Fibre Channel Short-Wave (SW) SFP+ Transceiver module engineered for high-performance SAN environments. Delivering up to 14.025 Gb/s per port, it's compatible with legacy 8 Gb and 4 Gb FC systems while supporting high-throughput end-to-end FC connectivity. With an LC duplex connector operating over multimode fiber at 850 nm, the module offers a reach of up to ~100 m (OM4/OM5), making it ideal for inter-shelf links, SAN edge ports, or server/storage uplinks. Integrated Digital Optical Monitoring (DOM) enables real-time diagnostics of link health including optical power, temperature, and voltage (per SFF‑8472 standard), enhancing manageability and availability in critical storage fabrics. Certified for use with HPE SAN products—including MSA, 3PAR, EVA, XP arrays and HPE Fibre Channell switches—this module ensures vendor-level compatibility and support.

Features

Built to industry standards (SFP+, SFF-8431, FC-PI-5) and fully qualified as an OEM FC transceiver, the C8R24B is a plug-and-play solution across many HPE storage and FC switch platforms. It auto-negotiates supported FC speeds (16/8/4 Gb), enabling seamless integration into existing multi-speed fabrics or gradual infrastructure upgrades.Operable over multimode fiber with a minimum optical budget of ~2.7 dB, the module supports up to 100 m reach over OM4 or OM5 cables; transmit power spans –7.8 to –0.5 dBm, while receiver sensitivity reaches approximately –10.5 dBm. It supports Digital Diagnostics Monitoring (DOM) for proactive health monitoring if enabled on the fabric switch or controller.Designed for deployment in HPE /Aruba Fibre ChannelChannel SAN infrastructure—including MSA 2040, 3PAR, EVA, XP, and switch products—the C8R24B module is widely employed in storage environments where performance and reliability are critical. OEM certification ensures support for features like fabric path analytics, zoning, Linkset, FICON or MSA fabric tools. Packages typically ship in 4-packs, though single-module deployment is supported.

Advanced Options

Engineered for enterprise-grade Fibre Channel fabrics, the C8R24B delivers reliable high-speed performance with predictable latency and throughput. Its short-wave design suits rack-to-rack or shelf-level SAN interconnects. Backward compatibility with 8 Gb and 4 Gb speeds allows phased upgrades without service interruption.DOM functionality enables SAN managers to monitor key optical parameters—such as Tx/Rx power, temperature, voltage—via switch or controller dashboards. This capability supports proactive diagnostics and helps prevent fiber disruptions before they impact the fabric.
