QSFP28 LR4 ZKTel’s QSFP28 transceiver modules are designed for use in 100 Gigabit Ethernet links on up to 10km of single mode fiber. They are 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...
QSFP-100G-ER4L-S is designed for extended reach 100 Gigabit Ethernet link. The 100GBASE-ER4-Lite QSFP28 supports both 100GbE and OTU4 applications over single-mode fibers, and supports up to 40km with FEC and up to 30km without FEC. 100G QSFP28 ER4 Lite module consumes 4.5W power in max.
The 100 Gigabit Ethernet signal is carried over four independent channels over four LAN-WDM wavelengths—1296nm, 1300nm, 1305nm, 1309nm. Multiplexing and demultiplexing of the four wavelengths are managed within the device. This QSFP28 was standardized by ITU-T as G.959.1 4L1-9D1F and 4-Wavelength WDM MSA Group. The following table displays the existing 100G QSFP28 MSA optics in detail.
