Optical Automatic Protect System - BC-Optics (HK) LIMITED

The BC-IA Optical Automatic Protect System (abbr. OAPS) detects the optical power of main equipment or channel by real time to protect optical communication. When the power is under the threshold value which is set by user, the OAPS will switch to standby channel and give warning with current power. If the OAPS detects that the main channel’s power rose over the threshold value, it will switch to main channel and ensure continuous communications.

pm?#	retain to main route optical power (dbm)	±XX.XX
ps?#	return to standby route optical power (dbm)	±XX.XX
sw?#	return to working channel	When return value is one, work for the main route. When return value is zero, work for the standby route.
au?#	return to the current working mode	When return value is zero, it is the manual mode. When return value is one, it is the automatic mode.
sm?#	return to the switching value of main route （dbm）	±XX.XX
am?#	return to the warning value of main route（dbm）	±XX.XX
ss?#	return to the switching value of standby route（dbm）	±XX.XX
as?#	return to the warning value of standby route（dbm）	±XX.XX
tm?#	return to the warning state of main route	When return value is zero, it is no warning. When return value is one, it is warning.
ts?#	return to the warning state of standby route	When return value is zero, it is no warning. When return value is one, it is warning.
sw1#	set access as main route	If set successful, return to ‘OK’.
sw0#	set access as standby route	If set successful, return to ‘OK’.
au1#	set the machine as automatic working mode	If set successful, return to ‘OK’.
au0#	Cancel automatic working mode	If set successful, return to ‘OK’.
am±xx.xx#	set the warning value of main route（dbm）	If set successful, return to ‘OK’. For example, if set the warning value of main route as -10.50dbm, the concrete order is am -10.50#
