Dualcomm patent-pending ETAP-XG 10G Network TAP is an amazing invention that will surely be loved by many IT professionals who need a "One Size Fits All" Network TAP to capture data traffic of either copper or fiber link at data rates from 100Mb/s to 10Gb/s. This is made possible by Dualcomm's patent-pending XGigabit Sniffer Technique and that the two inline network ports and two monitor ports of ETAP-XG 10G Network TAP are implemented as SFP+/SFP slots, each of which can accept a copper or fiber SFP/SFP+ transceiver module. Each of the two monitor ports outputs a copy of inline data traffic in one direction so that ETAP-XG 10G Network TAP will not drop any packets no matter how busy data traffic is. ETAP-XG doesn't introduce any packet delay, it can be used in a real-time industrial network. When ETAP-XG is used as an optical TAP, there is no need to specify the optical split ratio as is usually required by many optical TAPs on the market. Also, the two monitor ports can be configured as two copper RJ45 ports. ETAP-XG is also designed to operate under an extended temperature range from -25°C to 85°C for various industrial environments.
