BATM offers the finest available twisted pair to fiber optic transceivers. The proliferation of cost-effective fiber optic solutions, such as MT-RJ, allows fuss free extension of the local area network far beyond the limits of the traditional copper infrastructure. LANs can be extended to distances of up to 2 kilometers (1.24 miles) using multi-mode fiber. Six diagnostic LEDs for power, speed, copper and fiber link/activity, and copper and fiber full-duplex collision make supervision of the transceiver is simple. The modular nature of the transceivers allows it to be used alone or grouped together with other transceiver in a chassis.
