The IBM ACHT - 8 Gb FC LW SFP Transceivers (Pair) is a high-performance, fiber channel transceiver pair designed for long-wavelength (LW) applications, enabling data communication over long distances. Each transceiver in the pair operates at a data rate of 8 Gbps, which provides a robust solution for storage networking, data center, and high-performance computing environments seeking to enhance their system's fibre channel connectivity. These devices are designed to be inserted into the SFP ports of IBM storage systems or SAN (Storage Area Network) switches, providing an upgrade path for network infrastructure. They support distances up to 10 kilometers on single-mode fiber, ensuring connectivity across extended data center layouts or between distributed data centers. The transceivers are hot-swappable, allowing for minimal downtime during installation or replacement. They comply with the industry-standard SFP form factor, making them compatible with a wide range of IBM equipment and ensuring ease of integration into existing networks. The IBM ACHT - 8 Gb FC LW SFP Transceivers (Pair) represents a reliable, long-distance communication solution that leverages the efficiency and stability of fibre channel technology.
