Distributed Feedback Laser
Distributed Feedback Lasers are either semiconductor lasers or fiber lasers, operating on a single resonator mode. In the case of a fiber laser, the distributed reflection occurs in a fiber Bragg grating, typically with a length of a few millimeters or centimeters.
MACOM’s Distributed Feedback laser (DFB-Laser) diodes are designed for continuous wave (CW) operation up to 25Gb/s. These products utilize patented Etched Facet Technology (EFT) for exceptional reliability.

MACOM Technology Solutions Holdings, Inc. (MACOM) is a leading supplier of high performance semiconductor products that enable next-generation Internet and communications applications.
DFB lasers are primarily used in optical networks, for example, Gigabit Ethernet (GbE), 10 Gigabit Ethernet and 100 Gigabit Ethernet with distances up to 40 km, as in 100GBase-ER4. The extension ER4 means: "E" Extra Long and represents the wavelength; "R" designate the interface type as 64B / 66B encoding and the "4" indicates that the transmission using DWDM technology over four DWDM paths (Dense Wavelength Division Multiplexing, an optical wavelength division multiplexing) at a duplex single-mode-fiber connection.
