The CISCO 30-1299-03 transceiver module is a high-performance, cost-effective optical transceiver designed to support Gigabit Ethernet applications across extended distances. This hot-swappable input/output device plugs into a Gigabit Ethernet port or slot, enabling a fiber optic link. Compatible with the IEEE 802.3z 1000BASE-LX standard, it is designed for large data center networks, corporate backbones, metro Ethernet services, and other optical network high-speed data applications. This module can transmit over both single-mode (SMF) and multimode fibers (MMF), offering a maximum distance range of up to 10 kilometers on SMF and 550 meters on MMF with a wavelength of 1310 nm. Its flexibility of support for both LX and LH (Long Haul) applications makes this transceiver a versatile solution for extending network reach beyond the typical boundaries of Ethernet cabling. With its low power consumption and advanced optical technology, the CISCO 30-1299-03 ensures reliable performance for critical network infrastructure.
