The Hotcom 100G QSFP28 LR4 10km optical transceiver HT100G-QSFP28-LR4 for 100GE, HT100G-QSFP28-LR4-O for 100GE/OTU4) is designed for Data Center 100GBASE-LR4 Ethernet and OTN OTU4 links reach up to 10km over Single-Mode Fiber (SMF).
The HT100G-QSFP28-LR4/HT100G-QSFP28-LR4-O module converts 4 input channels of 25.78125Gb/s or 27.95Gb/s electrical data to 4 channels of LAN-WDM optical signals and then multiplexes them into a single channel for 103.125Gb/s or 111.8Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes the 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. The high-performance cooled LAN-WDM DFB transmitters and high-sensitivity PIN receivers provide superior performance for 100-Gigabit Ethernet applications up to 10km links and compliant to optical interface with IEEE 802.3ba Clause 88 100GBASE-LR4 requirements.
