Model 1935F Coaxial DFB Laser Diode
O-Band CWDM, CATV Forward Path 47 MHz – 1002 MHz
Emcore’s Model 1935F 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.

Absolute Maximum Ratings1
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in
excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.
