Model 1933 1310 nm CATV Coaxial DFB Laser
Diode
Emcore’s Model 1933 DFB lasers offer a low cost solution for linear
fiberoptic links. These components can be cooled with external thermoelectric coolers for high stability, or run without TEC’s to reduce power
consumption. The DFB laser builds upon Ortel’s long history of high
performance, leading edge designs in CATV, wireless, and high speed
digital applications. The laser diode devices are packaged in a compact
