The filter is capable of increasing network capacity by using Dense Wavelength Division Multiplexing technology.

The low ripple values enable it to stand among the best industry performers, providing up to 20 times better performance.

Bookham's product line manager Anthony Abdilla, commented on the technology "Our ripple values demonstrated with this filter are as much as 20 times better than the industry norm. Bandwidth expansion over analog transmission requires the flattest, highest performance ripple filters to ensure low interference and high CSO (composite second order) values, and with the product successfully qualified and into full-volume production we are ideally suited to meet the needs of the major cable operators and service providers."
