Product Description
The IBM 21H9876 GBIC transceiver module is a key component for establishing high-speed network links within compatible IBM hardware. It supports Gigabit Ethernet speeds, operating under the 1000Base-SW standard, which is optimized for short-wavelength transmissions over multimode fiber. This makes it an excellent choice for local area network (LAN) deployments where data needs to travel across shorter distances, such as within a data center or office floor. This module utilizes the GBIC (Gigabit Interface Converter) form factor, a predecessor to the more compact SFP modules, but still widely used in many enterprise networking environments. The 1000Base-SW designation indicates its suitability for short-reach applications, typically up to 300 meters on certain types of multimode fiber. The use of short wavelengths, commonly 850nm, is characteristic of this standard and its application with MMF. With its SC duplex connector, the 21H9876 ensures a secure and robust physical connection for the fiber optic cable. This is crucial for maintaining signal integrity and preventing data loss. The module is designed for plug-and-play installation in compatible GBIC slots, allowing for quick deployment and easy maintenance of network infrastructure. It represents a reliable option for organizations looking to maintain or expand their Gigabit Ethernet capabilities.
