QSFP-40G-SR Nokia Compatible 40G SR4 150m MMF Transceiver

For short-reach 40G aggregation inside the row, the QSFP-40G-SR is the multimode optic that carries the load — an SR4-grade QSFP+ module reaching 150m over MMF. It terminates through a duplex LC face and moves 40G across switch-to-switch and top-of-rack links on Nokia (Alcatel-Lucent) platforms. The 150m MMF budget is the spec that scopes it to in-building fabric rather than campus distance.
