What are the meanings of the parameters of the GE optical modules of the NE40E?
34060207 optical transceiver module-SFP-1310nm-1.25Gb/s-5dBm--2dBm--23dBm-LC-40km
The explanation is as follows:
"5" indicates the lower limit of transmit optical power.
"2" indicates the upper limit of transmit optical power.
"23" indicates the lower limit of receive optical power.
"40" indicates the transmission distance.
1.25Gb/s indicates the maximum signal transmission rate of the optical module. This value is generally slightly higher than the rate of a GE interface to guarantee the GE interface rate.
