Product Description
The IBM 21H9834 is a Gigabit Interface Converter (GBIC) transceiver module that supports the 1000Base-SX standard for Gigabit Ethernet networks. This module operates at a wavelength of 850nm, making it suitable for short-distance links utilizing multi-mode fiber optic cabling. The GBIC form factor was an earlier standard for network transceivers, often found in legacy networking equipment. Designed for short-reach applications, the 21H9834 can typically achieve distances of up to 550 meters over OM3 multi-mode fiber. It features an SC duplex connector, which is a common and robust optical connector type. This transceiver is ideal for connecting network devices within a building, such as between switches in a wiring closet or connecting servers to network infrastructure. As a hot-swappable module, the IBM 21H9834 allows for installation and removal without disrupting network operations, contributing to network uptime and ease of maintenance. Its adherence to the 1000Base-SX standard ensures compatibility with other network devices and infrastructure that support this widely adopted Gigabit Ethernet specification.
