Optical Path Deembedding
Enable
Select if you want the LCA to compensate for the optical
connections to the DUT.
Deembedding Data
Select how you want to specify the characteristics of the optical
path.
• Parameter lets you characterize the source or receiver
optical path by its length and refractive index, and
attenuation.
• Length (m) and Refractive Index can only be used
together. That is, you cannot give a value just for the
refractive index or just the length.

The value for the Refractive Index of a single-mode fiber is
typically 1.467 at 1310 nm and 1.468 at 1550 nm.

The value for the Refractive Index of a graded index multi-
mode fiber is 1.49 for 62.5µm at 850nm, 1.475 for 50µm at
850nm and 1.465 for 50µm at 1300nm.
• Attenuation (dB) can be used alone, or with the values
for length and refractive index.
• File lets you use the results of a measurement of the optical
path to characterize the source or receiver optical path.
