This IBM BN-CKM-QS-SR compatible QSFP+ transceiver provides 40GBase-SR4 throughput up to 300m over multi-mode fiber (MMF) at a wavelength of 850nm using a MPO connector. It is compatible with the equivalent IBM transceiver. This easy-to-install, hot-swappable transceiver has been programmed and uniquely serialized to ensure that it will initialize and perform identically. It is built to meet or exceed the specifications of IBM, as well as to comply with MSA (Multi-Source Agreement) standards to ensure seamless network integration.
