For long-distance transmission (>40km), no repeaters are required, reducing node costs by 50% compared with the 1310nm (collimator).

In quantum key distribution (QKD), the single-photon attenuation is 30% lower than that of the 1310nm (collimator), and the key generation rate is 25% higher.

Its human eye safety threshold (100mW) is 10 times that of visible wavelengths, requiring no safety interlocks.
