Description
The HP J4859C-NB, identified as a ProCurve X121 SFP transceiver, is designed for 1 Gigabit Ethernet (1GbE) network connections. This module adheres to the 1000Base-LX standard, which is optimized for longer-reach applications over single-mode fiber optic cabling. It is a key component for extending network connectivity in enterprise environments, campus networks, and between buildings. Operating at a wavelength of 1310nm, the J4859C-NB is specifically suited for single-mode fiber (SMF) deployments. It supports transmission distances of up to 10 kilometers, providing a reliable solution for inter-building links or backbone connections within a large facility. The module features an LC duplex connector, ensuring a secure and stable physical connection for the fiber optic link. This SFP transceiver is designed for hot-plugging, allowing for easy installation and replacement without the need to power down network equipment. It is compatible with HP ProCurve switches and other networking devices that support the SFP form factor. The J4859C-NB is an essential component for building robust and efficient networks requiring Gigabit speeds over extended distances on single-mode fiber.
