1933 F/R/W Coaxial DFB Laser Diode

1310 nm, Wide Bandwidth 5 MHz – 4000 MHz

DATASHEET | AUGUST 2012

FIBER OPTICS

EMCORE’s Model 1933 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.

Absolute Maximum Ratings¹

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress

ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the

operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect

device reliability.
