Supported wavelength or frequency configuration

Updated: June 16, 2026

Want to summarize with AI?

Adhere to these wavelength and frequency ranges when you configure channels that use the ONS-BRK-CS-8LC or ONS-BRK-CS-16LC passive mux cables on the QDD OLS pluggable to keep each channel within the supported operating bands.

For each channel that uses an ONS-BRK-CS-8LC or ONS-BRK-CS-16LC passive or mux cable, configure the channel’s wavelength or frequency according to the specified operating ranges listed in this table:

Table 1. QDD OLS operating signal wavelength range
Channel Spacing	Total Bandwidth	Wavelength		Frequency
Channel Spacing	Total Bandwidth	Start	End	Start	End
8 channels - 200 GHz spaced 16 channels - 100 GHz spaced	19.2 nm 2.4 THz	1539.1 nm	1558.4 nm	192.375 THz	194.775 THz
