    The AddOn QSFP-40G-SR4-S-AO is a Cisco-compatible 40GBASE-SR4 QSFP+ transceiver for network teams connecting compatible equipment over multimode fiber, with an MPO connector and a listed reach of up to 150 m.

    Recommended For

    • Network teams connecting Cisco-compatible switches across short data-center links that already use multimode fiber and MPO cabling; the Cisco SR4-S specification supports up to 100 m on OM3 or 150 m on OM4/OM5.
    • Data-center operators replacing or adding a 40G optical link between switches where the installed fiber plant supports parallel-fiber MPO connections and the switches accept Cisco-compatible QSFP+ optics.
    • IT teams sourcing a TAA-listed 40G multimode transceiver for a supported Cisco-compatible QSFP+ port, after confirming the exact switch and port compatibility.
