GENERAL DESCRIPTION

When configuring a network, the maximum number of nodes and the maximum cable length are limited by the electric capacity of the transceiver. In this case, the network is expanded by an equipment called a “HUB” or “repeater”. It maybe necessary to have a converter between coax, T/P and the fiber cable. It is easy to design a HUB or a repeater because the TMC2005 has various features for expanding such network.
