Product Description
The HP A7478A is a high-performance SFP transceiver module engineered for long-distance single-mode fiber (SMF) communication. With a data rate of 1.25Gb/s, it is commonly used for Gigabit Ethernet and Fibre Channel applications, providing a reliable link over extensive distances. The module's standout feature is its remarkable reach of up to 80 kilometers, making it an indispensable component for Wide Area Network (WAN) deployments, metropolitan area networks (MANs), and carrier-grade backbone connections where signal degradation over long fiber runs is a primary concern. Operating at a wavelength of 1530nm, this transceiver is designed to leverage the characteristics of single-mode fiber optics for maximum transmission efficiency and distance. The module is equipped with a standard duplex LC connector, ensuring compatibility with the vast majority of fiber optic cabling systems and network equipment. This combination of SFP form factor, SMF compatibility, and long-reach capability makes the A7478A a versatile solution for extending network connectivity across significant geographical areas. This HP transceiver module plays a crucial role in enabling robust and scalable network infrastructures that span large distances. It is essential for service providers connecting remote points of presence, enterprises linking distant branch offices, or any application requiring high-speed data transmission over long-haul fiber optic links. The A7478A ensures that critical data can be transmitted reliably and efficiently, supporting the demanding connectivity needs of modern telecommunications and enterprise networks.
