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.

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.

This product meets the appropriate standard in Title 21 of the Code of Federal Regulations (CFR). FDA/CDRH Class 1 laser
product. This device has been classified with the FDA/CDRH under accession number 0220191.
All version of this laser are Class 1 laser product, tested according to IEC 60825-1:2007/EN 60825-1:2007
Single-mode fiber pigtail with SC/APC connectors (standard).
Wavelength = 1.3 m.
Maximum power = 50 mW.
Because of size constraints, laser safety labeling (including an FDA class 1 label) is not affixed to the module, but attached
to the outside of the shipping carton. Product is not shipped with power supply.
Caution: Use of controls, adjustments and procedures other than those specified herein may result in hazardous
laser radiation exposure.
