Coaxial pigtailed laser diodes

The Coaxial pigtailed laser diodes are comprised of an uncooled quantum well DFB laser or FP laser chip, built-in InGaAs monitor photodiode, 4-pin coaxial pigtail type or plug-in type package, single-mode fiber coupling device, SC/APC or FC/APC optical connector, and built-in optical isolator. Its light source covers a wide wavelength range from 1270nm to 1610nm, totaling 18 wavelengths. Other typical values for the Coaxial pigtailed laser diodes are ±10nm for the spectral range, spectral bandwidth is 0.32nm, and output power range from 1MW to 7MW. This series of product is most commonly used in the WDM light source and communication systems, CWDM analog communication systems, CATV return-path transmission systems, and other analog transmission systems.


BoxOptronics Coaxial pigtailed laser diodes assemblies feature an integral optical isolator. The addition of these isolators provides protection against back reflections and ensures a minimum optical isolation of 30 dB at the specified center wavelength over the entire operating temperature range.


BoxOptronics Coaxial pigtailed laser diodes include InGaAs pigtail photodiode, 1270nm~1610nm CWDM laser diode, 1625nm 1650nm DFB laser diode, CWDM with TEC cooler etc.
