The IBM 4666-ACHX consists of four 100 Gigabit Ethernet QSFP28 SR4 transceivers designed for high-bandwidth networking requirements. Each transceiver in this set is built for superior network performance, supporting 100G speeds that are essential for modern data centers that demand high-capacity throughput for heavy data traffic scenarios. The QSFP28 SR4 model operates on the short-range (SR4) principle using multi-mode fiber, with an ability to cover distances up to 100 meters, thereby catering to the needs of within data center interconnects. Equipped with MPO connectors, these transceiver modules are optimized for reliability, durability, and low power consumption, making them an eco-friendly option for scaling network infrastructure.
