ImageStream WAN Monitoring Tapper

Network Tap Overview Download White Paper

ImageStream offers a wide range of passive network taps for LAN and WAN monitoring applications. These taps make it possible to monitor 10/100 ethernet and gigabit ethernet LAN traffic, as well as synchronous serial, T1, E1, HSSI, DS3, E3, OC3, and OC12 WAN circuits. Passive taps do not interrupt the flow of network traffic, which makes it possible to install them in a wide range of locations, and connect a monitoring station to the taps only when needed.

ImageStream monitoring taps are listed below with a short description for each. If you would like more specific information on these products, please follow the associated links.

Ethernet Taps
Ethernet taps are used to monitor fiber or twisted pair LAN connections. Stand-alone and rackmount versions are available.

Synchronous Serial Tap
The synchronous serial tap is used to monitor serial connections with data rates up to 4 Mbps. The tap is used in conjunction with a "Y" cable that provides different standard serial connectors including V.35, RS232, and RS422 with EIA530, RS449 or X.21 connectors.

T1/E1 Tap
The T1/E1 tap is used to monitor up to two T1 or E1 circuits. The tap also provides bantam connectors for monitoring data signals that are interconnected via a patch panel with bantam probes.

The HSSI tap is used to monitor high-speed synchronous serial interfaces operating at speeds up to 52 Mbps.

DS3 and E3 Taps
The DS3 and E3 taps are used to monitor the data traffic flowing across DS3 or E3 circuits.

Optical Taps
ImageStream's optical taps are used to monitor high-speed SONET and SDH interfaces operating at 155 Mbps and 622 Mbps, as well as fiber optic ethernet interfaces operating at 10 Mbps, 100 Mbps, and 1 Gbps. Rackmount and stand alone single mode and multimode versions are available.
