Product Description
The HP 378929R-B21 1000Base-SX SFP Transceiver is a key component for establishing Gigabit Ethernet connections over multimode fiber optic infrastructure. The 'SX' designation indicates that this transceiver operates at a wavelength of 850nm and is optimized for use with multimode fiber (MMF). This makes it suitable for shorter-reach applications within buildings, data centers, or campus networks where MMF cabling is already deployed. This SFP module plugs into compatible SFP ports on HP switches, routers, or network interface cards, providing a 1 Gbps connection. The typical maximum distance achievable with a 1000Base-SX transceiver is up to 550 meters over OM2 multimode fiber, and potentially further (up to 1km or more) over newer, higher-bandwidth multimode fibers like OM3 or OM4, depending on the specific transceiver and fiber quality. The LC connector is the standard interface for this type of SFP module, ensuring a secure and reliable connection to the fiber optic patch cord. The 378929R-B21 is hot-swappable, allowing for easy installation and replacement without interrupting network operations. It is an essential tool for network administrators looking to extend network connectivity, aggregate traffic, or connect network segments using cost-effective multimode fiber infrastructure at Gigabit speeds. Its compatibility with a wide range of HP networking equipment makes it a versatile choice for many enterprise deployments.
