with 3G2A9-AL002-E or 3G2A9-AL002-PE Link Adapters, the 3G2A9-AL004-E
or 3G2A9-AL004-PE Link Adapter would be replaced with a 3G2A9-AL004-E or
3G2A9-AL004-PE
3G2A9-AL004-PE Link Adapters would be inserted before each PC to convert
back to wire cable. The maximum transmission distance varies with the Link
Adapter and the kind of optical fiber cable as follows:
Cable
APF 20 m
PCF 200 m
APF: all-plastic fiber; PCF: plastic-clad fiber
