THGm (Ten/Hundred/Gigabit module)

A hardware device available from Finisar that allows the capture/transmit of net- work data at full line rate and supports real-time monitoring functions for 10/100/ 1000 Ethernets. The THGm card is for use with 1000BASE-SX, 1000BASE-LX, and potentially other types of gigabit networks. The 1000Mbps network interface for THGm is a removable G-BIC interface connector. THGm also supports 10/100 copper-wire networks. The 10/100 copper-wire network interface is an RJ45 con- nector.

THGnotebook (Ten/Hundred/Gigabit notebook)

Portable undercarriage unit with one or two THGm analyzer cards designed to oper- ate with a high-performance notebook computer. Connection to the notebook PC is via PCI bus expansion. THGm devices in a THGnotebook can by accessed locally or remotely by Surveyor software which provides the tools to diagnose, trouble- shoot, and monitor any full or half-duplex 10/100 Ethernet copper or Gigabit Ether- net fiber-optic network. THGp is often used in environments where a robust portable analyzer is needed.

THGp (Ten/Hundred/Gigabit portable)

ADolch PC-based portable network analyzing, troubleshooting, and monitoring system available from Finisar. THGm devices in a THGp can by accessed locally or remotely by Surveyor software which provides the tools to diagnose, troubleshoot, and monitor any full or half-duplex 10/100 Ethernet copper or Gigabit Ethernet fiber-optic network. THGp is often used in environments where a robust portable analyzer is needed to analyze protocols such as IP, IPX, or iSCSI.

THGs (Ten/Hundred/Gigabit system)

A network analyzing, troubleshooting, and monitoring system available from Finisar. THGs can by accessed locally or remotely by Surveyor software and pro- vides tools to diagnose, troubleshoot, and monitor any full or half-duplex 10/100 Ethernet copper or Gigabit Ethernet fiber-optic network.
