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 link s. These components can be cooled with external ther mo-
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 applicat ions. The laser diode devices are packaged in a compact
hermetic assembly together with monitor photodiode and isolator, for
flexible integration into various transmitter configurations.
