Description
CiDRA provides custom gain flattening filters on an OEM
basis that reduce nonuniform gain variation inherent with
optical fiber amplifiers. 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.
Features
•Passive athermal operation over C- or L-Band
•Exceptional wavelength and amplitude stability
•Precise tailoring of filter function to customer profiles
•Low excess loss
•Short period Bragg grating technology
•Compact package, standard fiber pigtails
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
