Telesail QSFP28 100GBASE-LR4 transceivers are designed for 100 Gigabit Ethernet links over 10km kilometers on standard single-mode (SMF) fiber (9/125) with duplex LC connector, and it fully compliant to the QSFP28 MSA, IEEE 8/ 02.3ba 100GBASE-LR4 and IEEE 802.3bm CAUI-4.
It is running at four optical wavelengths (1295.56 nm, 1300.05 nm, 1304.59 nm, 1309.14 nm) and multiplexing/de-multiplexing of these wavelengths happening inside CFP module according to the IEEE LR4 recommendation. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP28 MSA
The transceiver's designs are optimized for high-speed computing networks, data center, service provider applications. It offers a variety options to meets the different requirement.
