AC – Alternating current DC – Direct current Fuse Volts Volt amperes WARNING The procedure can result in serious injury or loss of life if not carried out in proper compliance with all safety instructions. Ensure that all conditions necessary for safe handling and operation are met before proceeding.
Page 11: Operating The Unit
Operating the Unit Warning To avoid the risk of injury or death, always observe the following precautions before initializing the unit: • Never look into the end of an optical cable connected to an optical output device that is operating. Laser radiation is invisible, and direct exposure can severely injure the human eye or skin.

Page 15: Safety Interlock And Remote Interlock
Safety Interlock and Remote Interlock The system interlock line is a hardware safety line that controls the signal output of all laser sources within the MAP system. The interlock line connects the MAP chassis to each laser in the system. If the interlock circuit is broken, interlock is considered activated and all laser sources are immediately disabled removing all light at the output connectors.

MAP Local Interface Module. The system level commands and instructions can be found in the MAP (Multiple Application Platform) User’s Manual (JDS Uniphase part number 10108925). MAP command syntax follows general SCPI rules. The MAP command set is separated into the following subsystems: INITiate Define the measurement acquisition parameters.
Page 26 Table 7 contains the commands for the EDFA cassette. Each command header in the command tree has both a long form and a short form. The long form notation has lower and uppercase letters. The uppercase characters represent the minimum characters required for the short form command to be recognized as valid on MAP.
