IBM 21H9882 1Gb/s Long Wave Gigabit Converter GBIC Transceiver Module

Product Description

The IBM 21H9882 is a Long Wave (LW) GBIC (Gigabit Interface Converter) transceiver module designed for 1 Gigabit Ethernet (GbE) networks. GBIC is an older standard for network interface modules, typically found in enterprise network equipment from an earlier era. This module specifically uses long wave optics, which are engineered to transmit data signals over extended distances, making it suitable for connecting network devices across larger facilities or between buildings where longer cable runs are required. This transceiver module converts electrical signals from the host network device (like a switch or router) into optical signals for transmission over fiber optic cable, and vice versa. The 1 Gb/s speed ensures robust performance for standard Ethernet networking tasks, while the 'Long Wave' capability allows for greater reach compared to short wave transceivers. The typical connector for GBIC modules is an SC duplex connector, providing a secure physical connection to the fiber optic cable. As a hot-pluggable component, the 21H9882 can be installed or removed from a compatible GBIC slot without disrupting network operations. This feature is essential for maintaining network availability and simplifying maintenance procedures. It serves as a critical link for extending Gigabit Ethernet connectivity in environments where distance is a factor.
