1270nm 5mW TO-CAN DFB Laser Diode
Product Description
Product Detail
2. Introduction of 1270nm 5mW TO-CAN DFB Laser Diode
This 1270nm 5mW TO-CAN DFB Laser Diode is a product operable over a broad temperature range with a low temperature-wavelength coefficient. It is well suited for applications such as communications research, interferometry, and optical reflectometry for distance measurement in fiber or free space. Each device undergoes testing and burn-in. This laser comes packaged in a 5.6 mm TO Can. It contains an integrated aspheric focusing lens in the cap, allowing the focus spot and numerical aperture (NA) to be matched to SMF-28e+ fiber.
