Product Description
The HP J4858C-OB, part of the HP ProCurve X121 series, is a Small Form-factor Pluggable (SFP) transceiver module designed for 1 Gigabit Ethernet (1GbE) networks. It specifically supports the 1000Base-SX standard, which is optimized for short-wavelength transmission over multi-mode fiber (MMF) optic cables. This transceiver operates at a wavelength of 850nm and is capable of supporting data transmission distances of up to 550 meters. This makes it ideal for network connections within a building, data center, or campus environment where moderate distances need to be covered. The module utilizes an LC duplex connector, a compact and secure interface commonly used for fiber optic connections. Designed for seamless integration with HP ProCurve switches and other compatible networking equipment, this SFP transceiver provides a plug-and-play solution for network expansion and connectivity. It ensures reliable performance for applications such as connecting switches, routers, or servers over fiber optic links, contributing to the overall flexibility and performance of the network infrastructure.
