The Cisco QSFP-40G-SR4 is a high-performance 40 Gigabit Ethernet QSFP+ optical transceiver designed for short-reach data communication over multimode fiber (MMF). It is widely deployed in enterprise networks, cloud data centers, and high-speed switching environments where reliable and cost-effective 40G connectivity is required.
Operating at an 850nm wavelength, this module uses VCSEL laser technology and an MPO/MTP-12 interface to deliver stable and efficient parallel optical transmission. It supports distances of up to 100 meters on OM3 fiber and 150 meters on OM4 fiber, making it ideal for high-density short-range interconnects.
Fully compliant with IEEE 802.3ba 40GBASE-SR4 and QSFP+ MSA standards, this module ensures seamless interoperability with Cisco networking equipment such as Nexus, Catalyst, and ASR series switches.
