Introduction
Get total traffic visibility for 10/100/1000 monitoring and security devices
by placing Net Optics Gig Zero Delay Taps and 10/100/1000 BaseT Taps on
critical network links. These Taps support passive monitoring of 10/100/1000
links at 10, 100, or 1000 Mbps. “Passive” means that network traffic continues
to flow even when the Tap does not have any power. These devices are ideal
when a passive Tap is required for use with a variety of copper monitoring
devices. (The link speed and the monitoring device speed must be the same;
the Tap does not perform data rate conversion.)
For superior reliability, these Taps feature Link Fault Detect TM (LFD), which
gives the devices connected to the Tap critical information about link status. If
either side of the bi-directional link fails, the Tap immediately communicates the
fault to both devices, reducing the time required to activate a redundant path.
Transparent Access
The Gig Zero Delay Taps and 10/100/1000 BaseT Taps establish permanent
passive access ports without introducing a point of failure or disturbing
other network connections. The Gig Zero Delay Tap either auto-negotiates
communication or uses an external DIP switch to set fixed speed and duplexing
parameters. These passive Taps deliver full-duplex monitoring with zero impact
on network traffic around the clock.
True Zero Delay
The breakthrough design of the Net Optics Gig Zero Delay Taps (but not the
10/100/1000 BaseT Taps) ensures zero impact on network traffic when the Tap
experiences a power on or power off event. These devices are the world’s first
and only 10/100/1000 taps offering true “zero delay” technology.
Highly sensitive network locations can improve monitoring performance with
the innovative features of Net Optics Gig Zero Delay Taps. If power is lost to
other 10/100/1000 taps, the connected devices may introduce delays as they
detect the power loss and try to re-establish their link.
Net Optics’ pioneering design ensures that any loss of power to the Tap is
transparent to the network, and does not affect the flow of traffic through the Tap
– completely eliminating packet delay and loss as potential security issues.
