Description
The Cisco QSFP-40G-LR4-S is a QSFP+ transceiver for 40 Gigabit Ethernet over single-mode fiber, rated for links of up to around 10 km, the distance that covers buildings on one campus or two sites in the same city. The -S suffix marks Cisco's cost-optimized, Ethernet-only optic tier, so it is aimed at straightforward 40G aggregation and uplink duty rather than mixed transport roles. Where the same 40G link runs over multimode fiber, the QSFP-40/100-SRBD covers it on duplex strands.
