The DWDM DFB Butterfly analog Laser Diode For CATV Application is a Dense Wavelength-Division Multiplexing (DWDM) laser for analog applications. It features a distributed feedback chip that has been designed specifically for Radio Frequency (RF) applications. The DWDM DFB Butterfly analog Laser Diode has a wide temperature range for reliable performance in harsh node environments and narrow transmitter designs. It also features low adiabatic chirp to maximize signal quality in short and long lengths of fiber. The laser’s excellent inherent linearity minimizes degradation of the broadcast signals caused by quadrature amplitude modulated (QAM) channels. The versatile DWDM DFB Butterfly analog Laser Diode reduces cable network architecture fiber needs and lessens equipment requirements in the hub.

This 1350nm Coaxial DFB Pigtail laser diode has a built-in InGaAs monitor photodiode and an optical isolator integrated inside its package. This laser diode is suitable for applications in optical networks such as mobile communication systems and CATV systems.

The 1550nm DFB Butterfly Laser Diode, with 10mW,20mW output through 900µm fiber pigtail. The fiber is approximately 1M in length, with FC/APC or FC/PC connector. The laser is excess-stock, new-in-box, and includes datasheet and test data.

500um TO CAN InGaAs avalanche photodiodes APDs is the largest commercially available InGaAs APD with high responsivity and extremely fast rise and fall time throughout the 1100 to 1650nm wavelength range, the peak responsivity at 1550nm is idealy suited to eys-safe rangefinding applications, free space optical communications, OTDR and Optical Coherence Tomography. The chip is hermetically sealed in a modified TO package, pigtailed option is also available.
