AscentOptics’ 100G QSFP28 Single Lambda Optical Transceivers are mainly applied in 100G Ethernet. They are compliant with IEEE 802.3bm, IEEE 802.3cd and QSFP28 MSA standards. Compared to the traditional QSFP28 optical modules that uses four 25G optical channels, and the four optical channels realize 100G transmission through wavelength division multiplexing or channel parallel mode. 100G QSFP28 Single Lambda optical transceiveres use a single wavelenth of 1310nm or single channel of CWDM, DWDM wavelenth. The 100G single wave optical module realizes data transmission by using DSP to convert four 25G electrical signals into single wave 100G PAM4 optical signals, effectively reducing the internal optical complexity of the optical module. AscentOptics could offer a wide range of 100G QSFP28 single lambda optical transceivers, including DR1 with 500m, FR1 with 2km,LR1 with 10km and ER1-30 /ER1-40 up to 30km/40km. We could also supply 100G CWDM, DWDM and BIDI QSFP28 single lambda transceivers.
