The QSFP 40G iSR4 is a cost-effective short-reach 40G optical transceiver designed for high-speed data center and enterprise network environments. Operating at an 850 nm wavelength over multimode fiber, it supports up to 40 Gbps aggregated bandwidth via 4 parallel 10 Gbps channels. With an MPO/MTP connector, this module supports transmission distances up to 100 meters on OM3 and 150 meters on OM4 fiber. The "i" in iSR4 typically indicates improved performance or interoperability in high-density environments.
