QSFP28 transceiver modules are designed for use in 100 Gigabit Ethernet links on up to 10 km of single mode fiber (CWDM4 wavelength grid). Designed for outside plant applications with an extended temperature range (-20°C to +85°C), they are compliant with the QSFP28 MSA, CWDM4 MSA, 4WDM MSA, and portions of IEEE P802.3bm CAUI-4. Digital diagnostic functions are available via the I2C interface, as specified by the QSFP28 MSA and Finisar Application Notes AN-21535 and AN-21546. The optical transceiver is RoHS compliant as described in Application Note AN-2038.
