| DATASHEET| FEBRUARY 20, 2008 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 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 hermetic assembly together with monitor photodiode and isolator, for Applications Video signal distribution in HFC and FTTx nodes High linearity, low power fiber links Operating Case Temperature Range flexible integration into various transmitter configurations.

Model 1933F 1310 nm CATV Coaxial DFB Laser Diode DATASHEET| FEBRUARY 20, 2008 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.
