Product Description
This 1Gb/s SFP transceiver module, identified as HP J4858C/P (ProCurve X121), is designed for reliable short-reach connectivity using multi-mode fiber optics. It adheres to the 1000Base-SX standard, enabling Gigabit Ethernet speeds over distances up to 550 meters. The 850nm wavelength is typical for short-wavelength, multi-mode fiber applications, making it suitable for within-building or campus network links. The module features a standard duplex LC connector, ensuring compatibility with common fiber optic patch cords and network infrastructure. As an SFP (Small Form-factor Pluggable) module, it is hot-swappable, allowing for network changes and upgrades without the need to power down equipment, which is critical for maintaining network uptime. Specifically designed for HP ProCurve networking equipment, this transceiver provides a seamless integration solution for switches and routers requiring Gigabit Ethernet connectivity over multi-mode fiber. It is an ideal choice for connecting servers, switches, and other network devices within data centers, wiring closets, and other enterprise environments where short-to-medium distance links are required.
