Juniper Compatible 100GBASE-SWDM4 QSFP28 Optical Transceiver Module (MMF, 850nm, 100m, LC, DOM)

The Cisco Compatible 100GBASE-SWDM4 QSFP28 transceiver modules are designed for use in 100 Gigabit Ethernet links over duplex multimode fiber (MMF) using a wavelength of 850nm via a LC connector. This transceiver is compliant with the QSFP28 MSA and IEEE 802.3bm CAUI-4 electrical interface. Digital diagnostics functions are also available via an I2C interface, as specified by the QSFP28 MSA, to allow access to real-time operating parameters. Adopting SWDM technology, it provides the lowest total cost solution for enterprise data center upgrades to 100G Ethernet, by enabling the use of the existing 10G duplex OM3/OM4 multimode fiber infrastructure.
