The CISCO 30-1299-01 is a Gigabit Interface Converter (GBIC) module, designed to deliver high-speed data transmission over fiber optic networks. With its support for the 1000BASE-LX standard, this module can transmit data at gigabit speeds (up to 1 Gbps) over both multimode fiber (MMF) and single-mode fiber (SMF) at a wavelength of 1300nm. This makes it an ideal solution for extending network reach over longer distances, up to 10 kilometers on SMF, and up to 550 meters on MMF, depending on fiber quality, type, and other environmental factors. The versatility of the CISCO 30-1299-01 GBIC module allows it to be widely used in large data centers, enterprise networks, and metropolitan area networks (MANs), where reliable, high-speed data transmission is critical. It is designed for easy insertion and removal from compatible Cisco devices, making upgrades and maintenance straightforward. This GBIC module is well-suited for organizations aiming to enhance their network's efficiency and connectivity while maintaining scalability and flexibility in their network infrastructure.
