Appendix 1 GRID Table for WDM Wevelength
Some analytical functions refer to the GRID table for analysis(See the following table.)
The AQ6370D contains the nominal center frequencies specified by the ITU-T
(International Telecommunication Union-Telecommunication sector) G692 as the GRID
table. It also contains two tables: the standard GRID table created according to the pre-
defined wavelength (frequency) range and the custom GRID table that users can edit
freely.

Note
Concerning the units of wavelength axis for GRID tables, wavelength values and frequency
values can be changed by the setting of marker units.
The two GRID tables (standard and custom) have different parameter ranges, which are
shown in the following table.
Type Parameter Range
Standard GRID Table
Start frequency 192.1000 THz (fixed)
Stop frequency 196.1100 THz (fixed)
Reference frequency 176.3486 to 299.7924 THz
Frequency spacing To be selected from among
200 GHz/100 GHz/50 GHz/25 GHz/12.5GHz
Fixed GRID Table
Start frequency 176.3486 to 229.7924 THz
Stop frequency 176.3486 to 299.7924 THz
Reference frequency 176.3486 to 299.7924 THz
Frequency spacing 0.1 to 999.9 GHz
Standard GRID Table
This GRID table is created with pre-defined wavelength (frequency) ranges. It can be
created in the following manner by setting the reference wavelength (frequency) and
frequency spacing.
Custom GRID Table
Users can edit this GRID table freely. It is created automatically by setting the start/stop
wavelength (frequency), reference wavelength (frequency), and frequency spacing.
Users can add or delete an arbitrary channel to/from the created GRID table or edit
wavelength (frequency) values for each channel there.
