1955 F/R/W Coaxial DFB Laser Diode

1550 nm CWDM 5 MHz – 4000 MHz

DATASHEET | SEPTEMBER 2013

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 EMCORE and 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.
