The Gigalight industrial-grade 100G QSFP28 LR4 transceiver is designed with the reliable Japanese industrial-grade TOSA in the transmitting end, and adopts our high-quality self-developed thermal-design ROSA in the receiving end. In the condition of full temperature of -40 to 85 degrees, there is an excellent performance with a margin more than 31% in the Eye Diagram (as shown in the figure below) . Moreover, it has a power consumption less than 3.5W and can meet the demands of 10km fiber transmission with zero-error-rate at 100GE data rates. It is fully compliant with IEEE 802.3ba 100GBASE-LR4 standard and is an ideal choice for applications of relatively harsh environments, meeting customers' demands of particular applications and the optical transport network transmission between AAU and DU for the future 5G mobile fronthaul application.

The Gigalight industrial-grade 100G QSFP28 4WDM-40 transceiver adopts the reliable Janpanese industrial-grade TOSA and ROSA on both the transmitting and receiving ends. It has a low power consumption less than 3.8W at the full temperature range of -40 to 85 degrees, ideal for building green data center and reducing energy costs. Its ROSA adopts a highly sensitive APD photodetector with a sensitivity less than -16.5dBm. When the FEC function is enabled in the system side, it can transmit up to 40km and meet the requirements of the 100GE 4WDM-40 MSA specification. This optical transceiver provides a cost-effective long-distance Data Center Interconnection (DCI) solution for distributed data centers under harsh environments, and also meets the demends of the optical transport network transmission between AAU and DU for the future 5G mobile fronthaul application.

5G Fronthaul Network

There is no doubt that the future 5G network will more rely on the support of optical network. Meanwhile, the fronthaul to 5G needs a strong optical network due to the flat network architecture. Besides, the density and increasing number of base stations will lead a tremendous demand for optical fiber resources and broadband. The successful launch of industrial-grade 100G QSFP28 optical transceivers has not only enriched the 100G QSFP28 product line but also created a product line with unique features, which can better serve the 5G optical transmission demands and supply the gap in the market.
