Description

The IBM BN-CKM-QS-SR is a high-density, high-speed QSFP+ transceiver designed for demanding data center interconnects and high-performance computing environments. It supports a data rate of 40Gb/s, enabling rapid data transfer between servers, switches, and storage devices. The SR4 standard indicates its suitability for short-reach applications over multi-mode fiber. Operating at a wavelength of 850nm, this transceiver utilizes the MTP/MPO connector, which is designed to support multiple fiber strands within a single connector housing. This allows for parallel optics transmission, a key feature for achieving 40Gb/s speeds over multi-mode fiber, typically reaching distances up to 100 meters depending on the fiber quality (e.g., OM3 or OM4). This QSFP+ module is hot-pluggable, allowing for seamless integration and replacement without disrupting network operations. Its compact form factor and high port density make it an ideal solution for maximizing bandwidth in space-constrained data center racks. The BN-CKM-QS-SR is a critical component for modern, high-performance network infrastructures.
