Model 1935R, Coaxial DFB Laser Diode
O-Band CWDM, CATV Return Path 5 MHz – 200 MHz
Emcore’s Model 1935R DFB lasers offer a low cost solution for linear
return path 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.
