The 400GBASE OSFP Optical Module is a high-performance, cutting-edge transceiver designed for ultra-fast, high-bandwidth connections in data centers, high-performance computing (HPC), and other large-scale networking environments. This optical module is packaged in the OSFP form factor and operates using 850nm wavelength for short-range transmissions. The 400GBASE OSFP is equipped with 100G PAM4 modulation technology, which enables it to achieve high-speed data transmission with reduced signal interference and power consumption.With a low power consumption of less than 9W, the 400GBASE OSFP Optical Module offers an efficient solution for large-scale data networks that require high-density, high-speed connectivity. It supports transmission distances of 30 meters on OM3 and 50 meters on OM4 fiber cables, making it suitable for short-range connections in modern data centers. The module features an MPO-12/APC interface, ensuring seamless integration into existing fiber infrastructures.
This optical module supports the IB NDR protocol and is fully compliant with 400G Ethernet standards, providing optimal performance for both 200G and 400G interconnects. The 400GBASE OSFP SR4 optical module can be used for direct connection between two 400GBASE OSFP SR4 modules, and can also be used to branch an 800G OSFP optical module into two 400G OSFP optical modules, allowing for flexible deployment in network infrastructure.An important distinction to note is the difference between the flat top and finned top designs of the 400G optical module. The flat top version is typically used in network interface cards (NICs) or DPUs (data processing units), while the finned top version is designed for switches. Both options are available, and customers are encouraged to contact customer service for further guidance on which model best suits their application needs.
The 400GBASE OSFP Optical Module offers a high-capacity, energy-efficient solution for modern network applications, ensuring rapid and reliable data transmission in high-performance environments. Its advanced modulation technology, along with flexibility in design options, makes it an essential component for building next-generation network infrastructures.
