21H9907 - IBM Fibre Channel Optical Short Wave GIBIC Transceiver Module

Product Description

The IBM Fibre Channel Optical Short Wave GIBIC Transceiver Module, identified by the part number 21H9907, is a critical component for building and expanding Storage Area Networks (SANs). This module is designed to convert electrical signals into optical signals for transmission over fiber optic cables and vice versa, enabling high-speed communication between various SAN devices. The 'Short Wave' designation indicates that it operates using shorter wavelengths of light, typically used for shorter distances within a data center or campus environment. The GIBIC (Gigabit Interface Converter) form factor is a standard for many network interface modules, ensuring compatibility with a wide range of IBM and third-party networking equipment, including Fibre Channel switches, host bus adapters (HBAs), and storage arrays. Its hot-pluggable nature allows for installation or replacement without the need to power down the connected equipment, minimizing downtime and ensuring continuous operation of the SAN. This transceiver module plays a vital role in ensuring reliable and high-performance data transfer for storage traffic. By supporting Fibre Channel protocols, it provides the dedicated, low-latency, and high-bandwidth connectivity required for mission-critical applications that rely on fast access to shared storage resources. The use of optical technology offers advantages such as immunity to electromagnetic interference and the ability to transmit data over longer distances compared to copper cabling, making it the preferred choice for robust SAN deployments.
