QSFP28 100G LR4 10KM DDM Transceiver

QSFP28 100G LR4 10KM DDM Transceiver

QSFP28-100G-LR4 are designed for use in 100 Gigabit Ethernet links on up to 10km reach over SMF. The laser drivers control 4- Distributed Feedback Laser (DFB) with center wavelength of 1296nm, 1300nm, 1305nm and 1309 nm. The optical signals are multiplexed to a single –mode fiber through an industry standard LC connector. They are compliant with the QSFP28 MSA and IEEE 802.3bm 100GBASE-LR4 and CAUI-4.  Digital diagnostic functions are available via an I2C interface, as specified by the QSFP+ MSA. The optical transceiver is compliant per the RoHS Directive 2011/65/EU.
