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.
