Product Description
The HP J4858C-OEM is a Small Form-Factor Pluggable (SFP) transceiver module specifically designed for Gigabit Ethernet connectivity over multi-mode fiber (MMF). Adhering to the 1000Base-SX standard, this module operates at a wavelength of 850nm and is optimized for short-reach applications within data centers, enterprise campuses, and other environments where MMF infrastructure is prevalent. With a maximum transmission distance of 550 meters, this transceiver is ideal for connecting switches within the same rack, across adjacent racks, or between floors in a building. The use of multi-mode fiber allows for cost-effective cabling solutions for these shorter distances. The module is equipped with a duplex LC connector, which is the industry standard for fiber optic connections, ensuring a secure and reliable physical link. This 'OEM' version indicates that it is either an original equipment manufacturer part from HP or a compatible module designed to meet HP's specifications for their ProCurve networking product line. It provides a reliable and cost-effective way to upgrade or expand network connectivity, enabling high-speed data transfer between network devices such as switches and servers.
