Product Description
The HP J4858C-C ProCurve X121 is a versatile 1.25 Gigabit per second (Gb/s) Small Form-factor Pluggable (SFP) transceiver module designed for use with HP ProCurve networking switches. It adheres to the 1000Base-SX standard, which is optimized for Gigabit Ethernet communication over Multi-Mode Fiber (MMF) optic cables. This standard utilizes an 850nm wavelength, making it suitable for short to medium-distance network links within buildings or data centers. With a maximum transmission distance of up to 550 meters (approximately 1804 feet) over appropriate MMF cable (such as OM3 or OM4), this transceiver provides reliable connectivity for connecting switches, servers, or other network devices. The duplex LC connector ensures a secure and robust physical connection to the fiber optic cabling infrastructure. This module is a standard component for expanding network capacity and reach in environments utilizing HP ProCurve switches. Its hot-pluggable design allows for easy installation and replacement without disrupting network operations. The J4858C-C is an essential part for building out or upgrading Gigabit Ethernet networks where fiber optic connectivity is required for performance, distance, or electromagnetic interference immunity.
