Product name: HP 4-port XFP 8800 Module
Product number: JE178A
Product type: Connectivity Modules
Product series: HP Switch XFP Modules
This module provides four ultra-high-performance 10-Gigabit Ethernet connections.
10-Gigabit Ethernet is a standards-based method for connecting at a speed 10x that of Gigabit Ethernet, or 10 Gigabits per second, while retaining critical Ethernet properties such as pack format.
The module requires XFP-style transceivers, sold separately, to provide the physical media connection.
10-Gigabit Ethernet is the perfect aggregation technology when deploying gigabit to the desktop or for interconnecting core and distribution switches.
Use 10-Gigabit Ethernet to connect one Switch 8800 to another with a similar module, or to another switch with a standards-based 10GBASE-X connection.
Provides four high-performance fiber optic connections between devices for bandwidth-intensive applications.
Provides a migration path from multiple aggregated Gigabit Ethernet links to high performance 10Gigabit Ethernet switch-to-switch connections.
