1935 F/R/W Coaxial DFB Laser Diode
O-Band CWDM 5 MHz – 4000 MHz
DATASHEET | AUGUST 2012
FIBER OPTICS
EMCORE’s Model 1935 DFB lasers offer a low cost solution for linear fiber optic
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.
