The abbreviations TX and RX are used for transmit and receive respectively. These metrics refer to the server being monitored. So transmission from this server and reception by this server. For example, a download from a computer is transmitted traffic (TX), but receiving data by a computer is measured as traffic received (RX). Tx and RX rate refer to transmit or receive data rates. TX data refers to the amount of data transmitted, and RX data refers to the amount of data received.
RX level is the power of the received signal in dBm. Server modems normally transmit at 13 dBm by default. Ideally, the RX level should be in the 18-25 dBm range. If the RX level is below 25 dBm, the signal-to-noise ratio is likely to drop, meaning the speed will drop. To properly send data via light signals, the transmit signal (TX) of the fiber optic link at one end of the cable must match with the corresponding receiver (RX) at the other end.
The TX and RX frequencies are around 30 GHz and 20 GHz respectively.
The optical TX power of a fiber optic transceiver is the signal level leaving this device and must be within the transmit power range. RX power is the incoming signal level received from the far end device and should fall within the receiving power range. Single mode fiber optic transceiver is designed for long distance data transmission, while multimode fiber optic transceiver is for short distance connection. Generally, a multimode fiber transceiver can support a distance of 300m. Whereas, single mode fiber optic transceiver can operate up to 10 km.
The two most important factors of a transceiver module are output power (TX power) and receiver sensitivity (RX sensitivity). Optical TX power is the signal level emanating from this device that should be within the transmit power range. RX sensitivity is the incoming signal level received from the far end device and this value must be within the receiving power range.
