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.
