Product description

With a 20 nm bandwidth available in each range and ultra-low insertion loss, this coupler is designed for high reliability and low FIT rates, through robust fusion and advanced component packaging.

Within optical networks, the ultra-low insertion loss of the wideband coupler makes it easier to meet stringent optical power budgets. Components are available in a variety of package styles to suit a wide range of applications, including optical networking. Wavelengths other than 1310/1550 nm are also available as a custom product.
