The 400G QSFP-DD SR4 Optical Transceiver is a high-performance, state-of-the-art transceiver designed for ultra-high-speed, large-scale data center and enterprise network applications. It is packaged in the QSFP-DD form factor，making it ideal for applications that require a high number of ports and compact space. This optical transceiver uses 850nm wavelength for short-range transmission, ensuring fast and efficient data transfer over multimode fiber.
The 400G QSFP-DD SR4 Optical Transceiver utilizes 50G PAM4 modulation on the electrical side and 100G PAM4 modulation on the optical side. This enables efficient data transmission at 400G speeds while maintaining signal integrity and minimizing power consumption. With a power consumption of less than 8W, this optical transceiver provides an energy-efficient solution for demanding networking environments that require high bandwidth but also aim to minimize power usage. The 400G QSFP-DD SR4 Optical Transceiver supports MPO-12 (APC) interface and offers a maximum transmission distance of up to 100 meters over OM4 multimode fiber cables. It is compliant with 400G Ethernet standards, making it suitable for the latest high-speed Ethernet networks. However, it’s worth noting that the QSFP-DD form factor is not yet widely available for use in InfiniBand (IB) networks.
This optical transceiver is perfect for direct connections between switches and can also be used to connect switches to network interface cards (NICs). Additionally, it can be used in high-bandwidth applications, such as when an 800G optical transceiver is split into two 400G QSFP-DD transceivers, allowing for flexible and efficient network design.
In conclusion, the 400G QSFP-DD SR4 Optical Transceiver offers an advanced, high-performance solution for modern, high-speed networking. With its high bandwidth, low power consumption, and flexibility in various network architectures, it is a key component for next-generation data center and enterprise network deployments.
