Introduction
Net Optics GigaBit SX/LX to TX Tap simplies connecting GigaBit copper
monitoring and security devices to SX or LX ber network links. Convert SX
or LX to TX and tap into the link with one device, reducing cost and complexity at the same time. GigaBit SX/LX to TX Taps support passive monitoring
of GigaBit links at 1000 Mbps.
Transparent Access
GigaBit SX/LX to TX Taps establish permanent passive access ports without
introducing a point of failure or disturbing other network connections. These
passive Taps deliver full-duplex monitoring with zero impact on network
trafc around the clock.
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 trafc as if it were in-line,
including Layer 1 and Layer 2 errors.
Simply Plug It In
Full-duplex monitoring is a snap with supplied cables. All network and
monitoring cables necessary for plug-and-play deployment are included with
the Tap.
GigaBit SX/LX to TX Tap
Reliability
For extra uptime protection, Net Optics GigaBit SX/LX to TX Taps offer
redundant power connections. Should the primary power source fail, the Tap
automatically 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 trafc.

LED Indicators
• PWR 1/ PWR 2: Main and Redundant Power. If the Tap is deployed with
both power supplies, both LEDs illuminate when the Tap is plugged in. If
an LED is off, this indicates that the corresponding power supply is not
functioning.
• Link/Activity Indicators: If a good link is established, the LED illu-
minates a steady green. If there is current activity on this link, the LED
ashes.
