Optical module products

The Guangyuan Weilai 40G/100G series high-speed optical modules are mainly used in the field of high-speed data transmission. There are different series of products including 40G SR4/eSR4/LR4, 100G SR4/eSR4/PSM4/CWDM4/LR4/ER4/ZR4, which are mainly used in the interconnection of TOR switches and leaf switches, interconnection between leaf switches and spine switches, interconnection between spine switches and core switches, or telecommunications transmission in data centers.
The 40G/100G QSFP28 SR4/eSR4 series optical module is mainly composed of an 850nm VCSEL laser array and a PD detector array.
The 40G QSFP+LR4 and 100G QSFP28 CWDM4 series optical modules use four uncooled CWDM DFB lasers and one PD array.
The 100G QSFP28 LR4 series optical module uses four cooled Lan WDM DFB lasers and one PD array.
The 100G QSFP28 ER4/ZR4 series optical module uses four cooled Lan WDM EML lasers and one PD array, and the receiving end of the 100G ZR4 uses an SOA amplifier.
