Yes, there are some dual speed 100G/40G optics that can help you avoid costly replacement when you upgrade your network. These optics can operate at either 100G or 40G depending on the mode and configuration of the switch port. They also use the same duplex LC-connectorized multi-mode fiber infrastructure as 10G and 40G optics, so you don’t need to replace your existing fiber cable infrastructure.
The QSFP-100G-CWDM4 (up to 2km over duplex SMF) and QSFP-100G-PSM4 (up to 500m over parallel SMF), are dual-rate optics which be used in both 40G and 100G modes.
