Product Description
The IBM 21H9772 is a Gigabit Interface Converter (GBIC) module, a precursor to modern SFP modules, used for connecting network devices. This specific model operates at 1063 Megabaud (Mbd), which corresponds to the signaling rate for Gigabit Ethernet or Fibre Channel. The designation 'Short Length' indicates that it is optimized for shorter transmission distances, typically over multimode fiber optic cables, making it suitable for in-rack or intra-building connections. GBIC modules are hot-swappable, meaning they can be installed or removed from network equipment like switches or routers without requiring the device to be powered down. This feature is crucial for maintaining network uptime and facilitating easier maintenance or upgrades. The module typically uses an SC duplex connector for its fiber optic interface, providing a secure and robust connection. As an IBM part number, the 21H9772 is designed to be compatible with IBM's server and networking hardware. While GBICs are largely superseded by smaller and more versatile SFPs, they were a standard for Gigabit connectivity in their time. This module would have been used to provide Gigabit Ethernet or Fibre Channel connectivity to IBM systems or other network infrastructure that supported the GBIC form factor.
