LIGHT SOURCE AND POWER METER

As optical signals traverse the network, many variables can affect the quality of transmission. This is an important factor for network performance. Low signal strength that fails to meet the transceiver threshold translates to no connectivity and difficulty to scale capacity in future.

The light signal naturally reduces in power as it progresses so, to test the signal, technicians use an optical light source and power meter to inject light into one end and measure the signal at the end point. Low power could indicate there is a fiber defect impeding the signal, such as a macrobend or a bad connector, or a fiber break. Additional testing would be required to identify and locate the fault.
