SRX-QSFP-40G-SR4 Juniper Compatible 40G SR4 150m MMF Transceiver

Decoded, the title describes a 40G SR4 optic reaching 150m over multimode fiber on a duplex LC interface — the Juniper-coded version of exactly that, shipped as the SRX-QSFP-40G-SR4. It seats in a QSFP cage, comes up coded to the host so Juniper gear sees a native module, and links with no configuration step. At 150m over multimode the SR4 grade suits in-row and short data-center 40G runs, and it reports live optical diagnostics over DDM once the port is live.
