Product Description
The Black Box LH1690C-LC-R3 is a high-performance Gigabit Ethernet network interface card designed to provide robust and reliable network connectivity for servers, workstations, and other computing devices. Featuring a PCI Express 1.1 x1 interface, this card offers a significant upgrade path for systems requiring faster network speeds than standard Fast Ethernet or older Gigabit Ethernet solutions. The card's primary function is to enable high-speed data transfer over fiber optic networks. This specific model supports the 1000BASE-SX standard, which utilizes multimode fiber optic cables and operates at an 850nm wavelength. It is equipped with an LC duplex connector, a common and reliable interface for fiber optic connections. The 1000BASE-SX standard allows for network links of up to 550 meters (approximately 1804 feet) when used with 62.5/125µm multimode fiber, making it suitable for in-building or campus network connections. The card supports full-duplex operation, doubling its potential throughput. Included with the LH1690C-LC-R3 is a low-profile bracket, which enhances its compatibility with a wider range of chassis, including smaller form-factor systems. This network card is an excellent choice for applications that demand high bandwidth and low latency, such as network-attached storage (NAS), video streaming servers, or high-traffic workstations. Its reliable performance and fiber optic connectivity ensure data integrity and security over its operational range.
