ITF Telecom offers specialty Fiber Bragg Gratings and couplers for system manufacturers in the telecommunications market. Our high-reliability components and process meet the highest standards of the industry and the rigorous demands of undersea applications.
ITF Telecom's Fiber Bragg Grating products for telecom applications include pump locker for fiber lasers and amplifier systems, including the 9XXnm range for EDFA systems and 14XXnm window for raman amplifiers. They are available on PM or non-PM fiber. These products are offered with a very high production capacity to meet large volume demands. We focus on industry standards, but our writing process can be customized to meet a wide range of optical characteristics. If you need a custom solution, we have years of experiences in FBG manufacturing on single mode fibers, for all kinds of applications in telecom systems or more research-focused systems.
ITF Telecom also developed a method to write FBGs with a total control of the shape of the reflectivity spectrum. This has a direct application as gain flattening filters, where the grating spectrum is custom-designed to flatten an EDFA or Raman gain curve. They are used to improve the performance and simplify the system design for DWDM submarine systems. They feature low low insertion loss, PDL and PMD, and are available with our athermal packaging for undersea applications, with proven record of reliability field data.
