Model 1933F CATV Coaxial DFB Laser Diode

1310nm, Wide Bandwidth 5MHz – 2700MHz

Emcore’s Model 1933F DFB lasers offer a low cost solution for linear

fiberoptic links. These components can be cooled with external thermo-

electric 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

hermetic assembly together with monitor photodiode and isolator, for

flexible integration into various transmitter configurations.
