Critical TAP System
NCT3FO
Network Critical TAPs provide security managers with a safe and secure way to deploy network IDS sensors into full-duplex links. The Critical TAP System is a flexible range of durable and highly reliable network TAPs dedicated to leveraging nIDS sensor deployment across the whole LAN.

These fiber TAPs are fully passive, layer-one only devices designed for in-line installation into core network segments. Inside the TAPs both light-paths are split into two halves using high-grade closed fusion splice fibres, one half is passed back to the live network and the other is passed to the monitor port. Only the highest quality components are used throughout the construction of the TAPs to absolutely minimise insertion losses. The TAPs do not require power and do not constitute a point of failure.

The physical-layer nature of these devices means that they are compatible with all fiber network technologies from 10/100BASE-FX, to Gigabit and 10-Gigabit network speeds, even some WAN technologies.

The NCT3FO is a single unit for 1 segment, which can be rack mounted.


Supported Technologies
Passive – protects (isolates) the Live Network from receiving traffic back through the monitor ports. Allows network tools to be deployed in ‘stealth’ mode.
Fail-to-Safe – No point of failure – Input power voltage is continuously monitored; if the input voltage is outside nominal levels, then the Live Network Ports fail-closed, maintaining the network link. The proprietary fail-close circuitry is passive and requires no power.
1000BASE-LX – supports 1000BASE-LX Singlemode Fiber on Live Network Ports.
1000BASE-SX – supports 1000BASE-SX Multimode Fiber on Live Network Ports.
10GbE - supports 10-Gigabit Ethernet on the Live Network Ports.
LinkLock – 100% Uptime Guaranteed – A permanent link connection between the two network devices enables Zero Packet Loss on the Live Network Ports while power is turned on or off. Packet Injection is NOT supported in this mode. This feature is not supported at 1000Base-T.
RoHS Compliant - Fully complies with EC directive 2002/95/EC.



Placed between two network elements the Fiber TAP will breakout both RX and TX streams and send them separately to a network tool.
Critical TAPs for 10/100/1000 Base-FX networks are available as a single unit for 1 segment, which can be rack mounted, or as multiple units for up to 4 segments, with separate TAPs within the same rack mount chassis.
