  • How to calculate the quantity of optical module work

    How to calculate the quantity of optical module work

    The calculation is based on a simple formula: P = P (Tx) – P (Rx) Where: P (Tx) – transmitter power P (Rx) – receiver sensitivity The typical parameters of the equipment are as follows: output power of laser transmitters: from -5 to +5 dBm. Receiver sensitivity: from -18 to -30 dBm. The optical link budget in SFP modules refers to the total amount of optical power loss (measured in dB) that a fiber optic link can tolerate while still maintaining reliable communication between the transmitter and receiver. If the loss exceeds this reserve, the signal will weaken to a level where the receiver cannot process it correctly.
