Product Description CW-3012M/CW-3012S 10/100/1000M adaptive bridging converter supports two types of network connection media, namely 10/100/1000Base-TX UTP and 1000Base-SX/LX optical fiber. NT-3012M/S is used to convert one signal into centralized another for the easy connec tion of two network segments. The technical availability of 10/100/1000M self-adaptive solves the bottleneck problems in the practical application. NT-3012M/S can be used as an independent device; Its plug-in module can be mounted on the frame of NT series tra nsceiver for the convenience of centralize wiring in conformity with IEEE802. 3Z/AB 1000BASE-T/SX/LX standard, supports 10/100/1000Mbps Nway switch and 10/100/1000Mbps NIC internal power design allows the direct use of 100-240V AC built-in ventilation device to ensure the highest reliability of this device.
