QSFP-100G-LR-S Cisco Compatible 100G QSFP28 LR1 10km SMF Transceiver

On Cisco switching and routing gear this optic comes up as the host's recognized part, and the QSFP-100G-LR-S matches it: a 100G QSFP28 single-lambda LR module (LR1) carrying single-mode traffic to 10km through a duplex LC connector. One 1310nm optical lane running PAM4 per the 100G Lambda MSA and IEEE 802.3cu — not a four-lane LR4, and not interchangeable with one: the far end of the link must also be a single-lambda LR optic. The 10km SMF reach fits inter-site and datacenter interconnect links where 100G leaves the building. It seats in the QSFP28 cage and reports operating conditions over DDM.
