IBM 21H9872 1GB 500m Short Wave Optical Transceiver Module

Product Description

The IBM 21H9872 is a high-performance Small Form-factor Pluggable (SFP) transceiver module engineered to facilitate high-speed data transmission over optical fiber. Operating at a data rate of 1 Gigabit per second (Gbps), this module is specifically designed for short-wave applications, making it ideal for connecting network devices within a building or across a campus. The module utilizes multi-mode fiber (MMF) and supports distances of up to 500 meters, providing a robust solution for local area network (LAN) backbones, data center interconnects, and high-bandwidth workstation connections. The transceiver features an LC duplex connector, which is a standard for fiber optic connections, ensuring secure and reliable physical linking. Its short-wave operation typically corresponds to a wavelength around 850nm, which is common for multi-mode fiber transceivers. The SFP form factor allows for hot-swapping, meaning the module can be inserted or removed from network equipment like switches, routers, or network interface cards without the need to power down the device, minimizing network downtime. This IBM-branded transceiver adheres to industry Multi-Source Agreement (MSA) standards, ensuring compatibility with a wide range of networking hardware from various manufacturers. Its primary function is to convert electrical signals from the host device into optical signals for transmission over fiber and to convert incoming optical signals back into electrical signals. This makes it a critical component for enabling high-speed, reliable, and efficient optical networking.
