Mellanox Compatible Infiniband EDR Transceivers SFP28 25GbE SR 850NM 100M MMF

High Performance Computing (HPC) enables humans deep understanding of the physical world and workflow optimization in the field of manufacturing, sciences research, financial services and government & defence. HPC system contains several sub-systems, including computing, storage, networking, application software and orchestration. For organizations, these sub-systems must interoperate with seamless communication of high efficiency and flexibility to scale for future growth. 

Networking is critical for HPC, challenging the overall performance, and should be not a hurdle to the communications between the computing and storage devices. Enterprises normally use the traditional LAN Ethernet as a cost-efficient solution to interconnect servers and storage. However, for large HPC clusters, their massive data is far beyond the capacity of traditional LAN Ethernet. And, networking should enable less or even no latency between computing and data aggregation. The new HPC Architectures called Infiniband and Omni-Path are created for high throughput and low latency applications. 

Infiniband is known as a low-level input/output (I/O) communication architecture. For HPC, the repaid development of computing performance has been more and more challenged by the bottleneck of commonly used PCI hosts in the I/O system. Infiniband separates the I/O system from both servers, storage, and interprocess network host to improve communication and system flexibility to handle future growth. Infiniband is a flat structure creating the direct connection between various nodes based on trust-based and flow-control protocol, ensuring the integrity of the connection, offering abundant buffer space for data tracking and reducing the packet loss and delay of retransmitting, thereby improving the data transmission efficiency of the entire system.

In Infiniband industrial, Mellanox is the leading brand solution provider who connects most of the Top 500 supercomputers and plans on the cut-edge NDR 400G Infiniband technology to support future E-level supercomputing and machine learning platforms. 

Top-Trans SFP28-25G-SR is designed for creating Infiniband data links with the rate of EDR 25.78125Gbps. Using MPO-LC breakout cables, TSFP28-25G-SR can allow 25GBASE LAN to interoperate with Infiniband EDR 100G Infrastructure. This TSFP28-25G-SR is fully compatible with Mellanox Connect-4 MCX-4121A-ACHT, Connect-5 MCX-512A-ADAT, Connect-6 MCX631102AC-ADAT etc 25GBE Server Adapter. This SFP28 module supports the transmission distance of 100M over OM4 Multimode Fiber (70 over OM3). This SFP28 module offers high speed, low latency, low power consumption connection fully compliant with IEEE 802.3by, IEEE 802.3cc, SFF-8402, SFF-8472, 21CFP-1040 LC#50 7/2001. This SFP28 module features build-in DDM/DOM via the I2C Interface to monitor the operating status.
