Modulation Frequency Range 5 MHz to 2.5 GHz
[a] Ambient temperature change max. \ 0.5°C since normalization. TLS maximum power set to 0 dBm. Sweep over
specified wavelength range. Specification does not include instability in test device. Specified loss ranges include loss of
test device and any additional switches or connections in the optical path. Specification valid on day of calibration.
[b] Modulation frequency

mod
= 2 GHz. IFBW = 70 Hz, wavelength increment = 1 nm, PDA correction ON.
Note: for modulation frequencies, f
mod
, different from 2 GHz, uncertainties typically scale by the factor “2 GHz/ f

“.
[c] GD/CD Swept Mode.
[d] Based on phase measurement uncertainties and modulation frequency uncertainty.
For rGD >> 1000 ps add
