F：Optical power monitoring is carried out in test lead by Optical Power Monitor Module；
G：Alarm is produced when optical power down is to setting threshold value；
H：The optical signal of 1625nm wavelength is persistently separated from business optical cable by Optical Power Monitor Module and is transferred to OTDR moulds
Block, period measuring is carried out to receiving optical signal by OTDR modules and draws luminous power curve, and by test result and light work(
Rate curve transmission is to management control module；The reference curve of luminous power curve and setting is compared by management control module
Compared with by the trouble point that standby fibre can be accurately positioned with reference to GIS GIS-Geographic Information System；
I：Monitoring for protection pattern, light source module is added in the end of spare fibre, to standby fine transmission optical signal；
J：Optical power monitoring is carried out in test lead by Optical Power Monitor Module, produced when optical power down is to setting threshold value
Alarm；
K：The optical signal of 1625nm wavelength is persistently separated from standby fibre by Optical Power Monitor Module and is transferred to OTDR modules, is led to
OTDR modules are crossed to carry out period measuring to receiving optical signal and draw luminous power curve, and by test result and luminous power curve
It is transferred to management control module；The reference curve of luminous power curve and setting is compared by management control module, and carried
It is standby fine to show that user repairs in time；
L：The optical signal of 1625nm wavelength is persistently separated from business optical cable by Optical Power Monitor Module and is transferred to OTDR moulds
Block, period measuring is carried out to receiving optical signal by OTDR modules and draws luminous power curve, and by test result and light work(
Rate curve transmission is to management control module；The reference curve of luminous power curve and setting is compared by management control module
Compared with；
M：When business optical cable is decayed, transmission services are switched to by RTU units by foregoing standby fine transmission, to protect
Card business normal operation.
