Product Description
The IBM 21H9854 is a specialized GBIC (Gigabit Interface Converter) transceiver module that adheres to the 1000Base-LW standard. This designation indicates its capability for long-wave laser transmission, making it suitable for high-speed Gigabit Ethernet connectivity over extended distances, typically utilizing single-mode fiber optic cables. The 'LW' in the standard signifies its operation in the long-wavelength spectrum, which is optimized for longer reach compared to short-wave transceivers. This module is designed to be hot-pluggable, allowing network administrators to install or replace it without interrupting the operation of the host IBM system. This feature is crucial for maintaining network uptime in critical business environments. The 21H9854 is specifically engineered for use with IBM networking hardware that supports the GBIC interface, ensuring seamless integration and reliable performance within the IBM ecosystem. By enabling 1Gb/s data transmission over single-mode fiber, the IBM 21H9854 facilitates robust and high-performance network links between devices such as switches, routers, and servers, particularly in scenarios requiring communication over significant distances. Its adherence to the 1000Base-LW standard ensures compatibility and interoperability within networks designed for this specific type of fiber optic communication.
