Product Bulletin Add-Drop Modules This design is based on fiber Bragg grating technology that provides narrow channel bands with high isolation in the express channels. Temperature compensation of the gratings provides temperature sensitivity lower than 0.0005 nm/oC. The modules are designed to drop single or multiple WDM channels from network traffic and to pass other "express" channels. Many different module configurations can be designed to suit specific system requirements. Wavelength channels over the ITU grid at channel spacings down to 50 GHz can be combined into a single package. 1 Out (1) * * * channel spacing Passively compensated for environmental changes >30 dB isolation from express channels >25 dB isolation from neighboring channels Applications * DWDM * Add/drop channels from network traffic Single Channel Add Module Single Channel Drop Module In (1) Key Features * Module can be tailored to 50 GHz or greater Out (2) In (1) 2 Out (2) In (2) Model 25150 | 2 Optical Specifications Channel Spacing Channel bandwidth (@ - 0.5 dB) Center Wavelength Tolerance @ 25C Insertion loss, single drop channel Insertion loss, single add channel Insertion loss through single channel Adjacent Channel Crosstalk Crosstalk (all other channels) PDL PMD Return Loss Storage Temperature Operating Temperature 50 GHz ITU 0.09 nm ( 11 GHz) 0.025 nm ( 3 GHz ) < 2.4 dB < 2.4 dB < 1.5 dB <-25dB <-30dB <0.25dB < 10 ps >40 dB -40 to 85C -5 to 70C Package Dimensions Ordering information For more information on this or other products and their availability, please contact your local JDS Uniphase sales representative or JDS Uniphase directly at 613 727-1304, or by fax 613 727-8284, or via email at sales@ca.jdsunph.com, or visit our Web site at www.jdsunph.com.
