Insertion loss in an optical circulator refers to the reduction in optical power as light passes through the device. It is a critical parameter because excessive loss can degrade signal quality, reduce transmission distance, and lower data throughput. Standard single-mode optical circulators typically exhibit insertion losses below 1.0 dB for P-grade devices and below 1.3 dB for A-grade devices, while advanced low-loss designs can achieve less than 0.44 dB under optimal conditions . High-performance models also maintain polarization-dependent loss (PDL) as low as 0.05 dB .
