Description
The F-tone Networks 100GBASE-LR4 Lite 4km QSFP28 optical transceiver, 100G QSFP28 LR4L (FTQ2-HG-LR4Lxx) is designed for use in 100-Gigabit Ethernet links up to 4km on Single Mode Fiber (SMF). It is compliant with the QSFP28 MSA, IEEE 802.3ba 100GBASE-LR4, and IEEE 802.3bm CAUI-4. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP28 MSA. It converts 4 input channels of 25.78125Gb/s electrical data to 4 channels of LAN-WDM optical signals and then multiplexes them into a single channel for 103.125Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 103.125Gb/s optical input into 4 channels of LAN-WDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 LAN-WDM channels are 1295.56nm, 1300.05nm, 1304.58nm and 1309.14nm as members of the LAN-WDM wavelength grid defined in IEEE 802.3ba.
