Link Adapters AL002-(P)E and AL004-(P)E can be used to insert optical links between PC Link Units to extend transmission distance and provide superior re- sistance to noise. Optical links connect only Link Adapters; they do not directly connect to the PC Link Units themselves. In the diagram below, the straight lines represent wire cables and the jagged lines represent optical fiber cables.
