MX-481T-SC STATUS INDICATORS
The MX-481T-SC transmitter provides the following LED status indicators to aid in installation and
troubleshooting:
TX A
A green LED indicator is provided to monitor the data coming in from the electrical interface or the ‘B’
receive port, through the ‘A’ optical port of the MX-481T-SC, and out onto the fiber. The intensity of this
indicator will vary with input data patterns, however in typical applications it will cycle on and off as data
is transmitted. Data transmitted status associated with this LED is summarized below.

Green
Data Flow Present
Off
Data Flow Not Detected
RX A
A green LED indicator is provided to monitor the data coming in from the fiber, through the ‘A’ optical
port of the MX-481T-SC, and on to the ‘B’ optical transmit port. If this is the master unit, this data will
also be sent out on the electrical interface. The intensity of this indicator will vary with input data
patterns, however in typical applications it will cycle on and off as data is received. Data received status
associated with this LED is summarized below.

OLI A
A bi-color LED indicator monitors the optical input power of the data signal that is being received at the
‘A’ optical port of the MX-481T-SC from the corresponding MX-481T-SC or the RX-481T-SC. DC power
and optical input status associated with this LED are summarized below.
