Ferrule Type	Random Mating Attenuation 1 (≥97% dB)	Average Random Mating Attenuation (dB)	Return Loss (dB)
Single-mode Low-loss (Elite®)	≤0.25²,³	≤0.12²,³	≥60
Single-mode Standard-loss	≤0.50²,⁴	≤0.25²,⁴	≥60
Multi-mode Low-loss (Elite®)	≤0.25	≤0.12	≥25
Multi-mode Standard-loss	≤0.45	≤0.20	≥25

Performance may vary depending on different ferrules and fiber counts according to IEC 61755-3-31 (e.g., estimated attenuation of 0.35 dB for 12-fiber IEC Grade B with a yield rate of 93%).

1 IEC 61755-1 defines grades based on a ≥97% random mating loss probability for channels meeting or exceeding the loss specification.

2 IEC 61755-3-31 only applies to 12-fiber single-mode APC.

3 Exceeds IEC 61755-1 Grade B performance.

4 Meets IEC 61755-1 Grade C performance.

Ferrule Type	Insertion Loss (Typical)	Insertion Loss (Max)	Return Loss
Single-mode Standard-loss	0.20 dB	≤0.75 dB	≥60 dB (APC 8° angle polish)
Single-mode Low-loss	0.10 dB	≤0.35 dB	≥60 dB (APC 8° angle polish)
Multi-mode Standard-loss	0.20 dB	≤0.6 dB	≥20 dB
Multi-mode Low-loss	0.10 dB	≤0.35 dB	≥20 dB
