What are Cisco 40G Optical Modules?
Cisco 40G Optical Modules are hot-pluggable QSFP transceivers designed to enable 40 Gigabit Ethernet connectivity over multimode or single-mode fiber in Cisco switching and routing platforms.
Which Cisco 40G Optical Module models are available?
Cisco offers QSFP-40G-SR4 for short-reach multimode, QSFP-40G-LR4 for up to 10 km SMF, QSFP-40G-ER4 for up to 40 km SMF, and QSFP-40G-UNIV for dual-rate support.
What is the difference between QSFP-40G-SR4 and QSFP-40G-LR4?
QSFP-40G-SR4 uses 850 nm VCSEL over OM3/OM4 fiber for distances up to 150 m/400 m, while QSFP-40G-LR4 uses 1310 nm DWDM over single-mode fiber for distances up to 10 km.
