USRobotics 10/1 Gigabit LR/LX Single-Mode Fiber Tap - tap splitter - GigE,

The USRobotics 10 Gigabit Fiber Taps provide an easy method to rapidly and effectively deploy analysis tools to observe and monitor traffic non-intrusively between two devices on a fiber network. By design, fiber taps are totally passive, fault-tolerant, and invisible to the network which means they will not affect network performance or integrity and can be trusted for permanent installations on a fiber network that require a dedicated port mirror. These rock solid devices are ideal for real-time monitoring and analysis of any traffic between critical network devices such as switches, routers and firewalls and continue to pass errors that aren't seen using SPAN ports.
