AWG Characterization

For some details on spectral characterization see the technical note: AWG_Characterization

A. Test and Measurement

Experimental setup

Spectral response of a 48-channel AWG.

B. Data Analysis: Specifications

The data shown in the above figure are analyzed to extract the parameters shown in Table 1. These are typical values. The parameter definitions are given in Telcordia documents. A summary is given in the attached article as well: awg_characterization.pdf.

Passband uniformity (ripple) (dB)	1.5
Insertion loss (IL) (dB)	5
IL uniformity (dB)	1.5
PDL (dB)	0.5
Adjacent crosstalk	25
Non-adjacent crosstalk (dB)	30
