Specifications for optical to optical measurements at 1550 nm
N4373C system with network analyzer
E8361C/A -014
(O/O mode)
Specifications are valid under the stated measurement conditions.
At optical input 1 (“+7 dBm max”). At optical input 2 (“+17 dBm max”), specifications are typically the same for 10 dB
higher incident average and modulated optical power.
For external source optical input all specifications are typical [f2][f5][f6]
For wavelength:
(1550 ±20) nm (option -101,102)

[f2] For +5 dBm average output power from LCA optical output.
[f3] Except phase wrap aliasing (example: a DUT group delay of 5 ns (1 m cable length) requires a frequency step size of ≤ 0.2 GHz to avoid phase wraps).
[f4] For DUT response max. +6 dBe (+3 dBo ) gain.
[f5] After CW responsivity and user calibration with external source.
[f6] Requires option -100 or -102.
[f7] Average value over frequency range.
