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
