NOTE
1 When an optical fiber cable is used for connection.
2 For printed-circuit boards with the following former ordering information, the maximum
allowable transmission distance with A66L-6001-0026#L~ is lowered to 50m, and
connection with A63L-0020-0004 is impossible.
• A20B-8001-0580 • A20B-8001-0581
• A20B-8001-0640 • A20B-8100-0100
3 Only one relay point is permitted. And you can relay two optical fiber cables on condition
that the sum of the line length of two cables is within the range of the maximum allowable
transmission distance or less.
