1550nm thermally insensitive packaged fiber Bragg grating

Fiber Bragg gratings are widely used as wavelength filters in the communication field. The central wavelength of the fiber Bragg grating is highly sensitive to external temperature changes. This packaging utilizes unique technology to ensure that the central wavelength of the grating is unaffected by temperature variations.

Product features：100G/50G channel spacing、 Low insertion loss、 Excellent channel isolation

Application area：Local area network and backbone network、 Dense wavelength division multiplexing network、 Wavelength reference
