The physical status information consists of the following parameters.
When Receiver is set to OFF, 'N/A's are displayed.
Rx signal levelRx signal level
Signal Level (Optical) shows the optical signal level in dBm.
Signal Level (Electrical) shows the electrical signal level in dB.
'nan' is displayed when input level is too low to detect the signal level. The
lamp indicates LOS status.
DeviationDeviation
This field shows the deviation from the relevant nominal bit rate:
STM-1/1e: 155 520 000 bps
STM-4: 622 080 000 bps
STM-16: 2 488 320 000 bps
STM-64: 9 953 280 000 bps
Bit rateBit rate
The current bit rate is shown (in bps).
Pattern bit ratePattern bit rate
This field shows the effective bit rate of the patterns received (that is, the
number of pattern bits received per second).
Tx signal levelTx signal level
When optical is selected, this field shows the output power of the optical
transmitter.
When electrical is selected, 'N/A' is displayed.
