Does an optical power meter have a positive value for optical attenuation
Although meters measure a negative number for loss, convention has us saying the loss is a positive number, so we say the loss is 3. 0 dB when the meter reads – 3. The “m” in dBm refers to the reference. Typical power levels measured by an optical power meter: Telecom transmitters: 0 to +10 dBm (1 to 10 milliwatts), Receivers: -30 dBm (1 microwatt) DWDM systems with fiber amplifiers: +10 to +20 dBm (10 to 100 milliwatts), Receivers: -20 to -30 dBm (1-10 microwatt) Data links and LANs: 0 to -10 dBm. Actual optical attenuation = Upstream optical power on one side of the test point - Upstream optical power on the other side of the test point. It should be noted that decibel milliwatts less than 1mw are negative values. In addition to measuring optical power, optical power meters can also be used with light sources to measure optical loss.

What is an intelligent connected optical module
The intelligent optical module has high-precision sensing capabilities. It can extract receive optical power data at an interval of milliseconds, cache the collected data, and report the data to the NMS. With supercomputing and intelligent computing clusters rapidly moving towards the "supernode" era, interconnect technology is becoming a key factor in boosting system performance. As the number of GPUs multiplies, bandwidth demands exceed TB/s, and rack power density climbs to over 40kW. An intelligent optical module can collect the receive optical power data and work with the fault diagnosis function of the NMS to accurately determine the type of a fault on the client side. This helps data move faster and saves power. They make the signal path much shorter, from centimeters to millimeters. Co-packaged optics (CPO) (Figure 1) increases bandwidth by exchanging FPPs for small, high-density connectors.
