WebJan 13, 2024 · For general SFP optical modules, the values of Tx and Rx power within a specific range indicate that the SFP optical module can operate normally. The Cisco GLC-SX-MM optical module, for example, has a transmit power range of -9.5 to -3 dBm and a receive power range of 0 to -17 dBm. If Tx or Rx is in the range of -30 dBm or lower, it means that ... WebMar 5, 2024 · The transmitted optical power refers to the output optical power of the light source at the transmitting end of the optical module, and the received optical power refers to the input optical power of the light source at the receiving end of the optical module.
