50 GHz Fiber Bragg Gratings and Temperature Compensating with up to

Eight Packaged Gratings

DESCRIPTION

Fiber Bragg Gratings (FBG) are often used in telecommunication applications involving dense wavelength

division multiplexing (DWDM) and Optical Add-Drop Modules (OADM). Other FBG applications include

wavelength stabilization, dispersion compensation and gain flattening. In comparison to popular thin film

filters, FBG based devices promise to deliver the steep-skirted profiles necessary to provide high adjacent

channel isolation as the channel spacing in DWDM systems gets smaller and smaller. The in-fiber solution

of the FBG is also advantageous to system designers striving to reduce their network’s overall insertion

loss. Gould packaged DWDM fiber Bragg gratings offer flat top passbands, sharp spectral roll off and high

reflectivity with minimal thermal drift over a wide operating temperature range.

These 50 GHz DWDM packaged gratings offer exceptional performance. They provide flat top passbands

with sharp spectral roll offs, which are well suited for high performance DWDM systems. These gratings

are available with up to eight gratings in a single package.
