Yes, a beam splitter can be added at 19 dBm, but careful consideration of additional attenuation and splitting ratio is required.
A beam splitter divides an incoming light beam into two or more beams, either by intensity, polarization, or wavelength . When a beam splitter is introduced, some optical power is inevitably lost due to reflection, transmission, and absorption. The amount of loss depends on the splitting ratio (e.g., 50/50, 70/30) and the type of beam splitter (plate, cube, polarizing, or non-polarizing) . For example, a 50/50 non-polarizing splitter will reduce the transmitted and reflected beams to roughly half the original power, introducing approximately 3 dB of additional attenuation per path.
An optical power of 19 dBm corresponds to about 79 mW. Most standard beam splitters can handle this power without damage, as typical optical components are rated for tens to hundreds of milliwatts, depending on the coating and substrate . However, the effective power in each output beam will decrease according to the splitting ratio. For instance:
It is important to ensure that the reduced power is still sufficient for downstream components, such as detectors or fiber inputs, to maintain signal quality.
Adding a beam splitter at 19 dBm is generally feasible, but the resulting attenuation and power distribution must be carefully evaluated. Selecting the appropriate type, splitting ratio, and coating ensures that the system continues to operate efficiently without exceeding component limits .
Polarity testing generally can be done with a visual fault locator to confirm that fibers are connected per the documented cable
