1955 F/R/W Coaxial DFB Laser Diode

1550 nm CWDM 5 MHz – 4000 MHz

DATASHEET | AUGUST 2012

FIBER OPTICS

EMCORE’s Model 1955 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.
