Example of the Device Status and Configuration sub-menu:
<1> Device Service: Disabling the device will halt all traffic through all ports.
<2> Store Configuration: After making device changes, use this to store the parameters into NVR.
<3> Default Configuration: This will restore the parameters to factory default. Then do a ‘Store’ to write changes to NVR.
<4> Reset Device: This will reset the CPU and the switch on the device (warm start).
Digital Optical Monitoring
Modern optical SFP transceivers support digital diagnostics monitoring (DDM) functions according to the
industry-standard SFF-8472. This feature is also known as digital optical monitoring (DOM) and gives the end user
the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power,
temperature, etc. Parameters are read from any MSA compliant SFP module. Extended information is only
available in modules which support Digital Optical Monitor (DOM) function.
Example of reading Digital Diagnostics in SFP from Fiber sub-menu:
Auto Laser Shutdown
Automatic Laser Shutdown (ALS) is a technique used to automatically shut down the output power of the
transmitter in case of fiber break according to ITU-T G.664. This is a safety feature that prevents dangerous levels
of laser light from leaking out of a broken fiber, provided ALS is provisioned on both ends of the fiber pair. The
sequence of events is as follows. If a fiber is cut, the receiver will detect a Loss Of Signal (LOS). The ALS agent
will turn off the transmitter. The receiver at the far end will then detect an LOS and its ALS agent will turn off the
transmitter. In this way the entire fiber will go dark.
