Optical Tunable Filter Array
Download Datasheet (PDF)

Turnable Optical Filter (TOTF)The Lightwaves2020 Broadband tunable filter array is an 8-channel micromotor-driven optical tunable filter, in which the tuning is achieved by rotating a TFF filter. A wide variety of wavelength tuning ranges and profiles can be achieved by selecting the right thin film filter. There are options for the tunable filters of 100GHz or 50GHz channel spacing.
The tunable filter array is designed to have maximum tunable wavelength range, minimum insertion loss and minimum polarization dependent. It offers cost-effective and compact solutions for various applications, especially
in ROADM as tunable devices.
