These filters operate over a wide wavelength range, to cover either the entire EDFA C-Band or L-Band. Based on Bragg grating technology, these devices leverage CiDRA's proprietary waveguide platform technology to deliver filters with exceptional stability and performance. CiDRA's flexible, yet scalable, manufacturing process allows for the fast prototyping of devices tailored to specific customer profiles, and a rapid design to production cycle time. This process yields high-volume, repeatable products that deliver superior and uniform performance. -4 0.1 0 -0.1 -0.2 -0.3 -0.4 -0.5 1528 1533 1538 1543 1548 1553 1558 1563 Wavelength (nm) Applications * * * Both C- and L-Band EDFA gain flattening Long haul and ultra-long haul DWDM transmission Undersea systems Standards * Compliant with Telcordia GR-1209 and GR-1221 requirements C i D R A C O R P O R A T I O N * 5 0 B A R N E S PA R K N O R T H , W A L L I N G F O R D , C T 0 6 4 9 2 * ( 2 0 3 ) 2 6 5 - 0 0 3 5 * w w w . c i d r a . c o m CUSTOMER WORKSHEET O E M G A I N F L AT T E N I N G F I LT E R Please fill in your custom product specifications below: PARAMETER STANDARD SPECIFICATION Customer Specified 1525-1562nm, 1569-1605nm 0.5dB max across band Filter Profile Wavelength Range Error Function COMMENTS Tighter tolerances available, consult factory over operating temperature range Excess Loss <1.0dB PDL <0.2dB \ Temperature Dependence <0.5pm/C Tighter tolerances available, consult factory Operating Temperature Range -5C to +70C Extended range available, consult factory Optical Interface 1.0m 250um buffered fiber FC-PC/APC and E2000 connectors available (SMF 28 or equivalent) Standards Compliant with Telcordia GR-1209 and GR-1221 requirements Mechanical Drawing [<70mm] 2.75" [6.1mm] O.24" Fax completed worksheet along with your filter profile and custom specifications to CiDRA Customer Service.
