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.
Our suppliers in this category Distributed Feedback Laser:
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.
