Normal light emission power of optical module
Generally, for a standard 10G-SR (Short Range) module, the RX power should be between -2 dBm and -9 dBm. Always ensure the level is higher than the “Receiver Sensitivity” limit found in the Cisco datasheet. The average transmitted optical power refers to the optical power output by the light source at the transmitting end of the optical module under normal working conditions, which can be understood as the intensity of light. In communication, we usually use dBm to represent optical power. The. Optical module is a connection module for photoelectric conversion, in which the sender converts electrical signals into optical signals, and the receiver converts optical signals into electrical signals after transmission through optical fibers. The strength of this light is measured in dBm (decibel-milliwatts). These modules, including SFP, SFP+, and SFP28, are widely used in enterprise networks, data centers, and carrier-grade deployments. When designing optical networks, understanding the TX/RX power range is vital for ensuring optimal performance and long-term reliability.
