Introduction
Net Optics 10/100BaseT Taps supply mission-critical networks with superior
network visibility and security access. The breakthrough design of the Net
Optics 10/100BaseT Tap ensures zero impact on network trafc while main-
taining uninterrupted access for monitoring and security devices. These are the
world’s rst and only 10/100BaseT Taps offering “zero delay” technology.
The efcient 4 Station 10/100BaseT Tap connects up to four monitoring de-
vices to four different links, saving rack space, time, and money.
Zero DelayTM – A Net Optics Breakthrough
Highly sensitive network locations can improve monitoring performance via
the innovative features of Net Optics Taps. If power is lost to other 10/100
Taps, the connected devices may introduce delays as they detect the power
loss and try to re-establish their link.
Net Optics’ engineering breakthrough ensures that any loss of power to the Tap is
transparent to the network, and does not affect the ow of trafc through the Tap
– eliminating packet delay and loss as potential security issues.
Security and Visibility
Without an IP address, monitoring devices are isolated from the network,
dramatically reducing their exposure to attacks. However, the monitoring
device connected to the Tap still sees all full-duplex trafc as if it were in-line,
including Layer 1 and Layer 2 errors.
Reliability
For extra uptime protection, Net Optics 10/100BaseT Taps offer redundant
power connections. Should the primary power source fail, the Tap automati-
cally switches to the backup power source. Power LEDs on the front of the
Tap indicate the current power source – even if power is lost and reapplied,
there is always zero delay to network trafc.
