1997 Uncooled, Coaxial DFB Laser Diode
1270/1290/1310/1330/1350/1370/1530/1550 nm Wide Bandwidth 300 MHz – 6 GHz
DATASHEET | APRIL 2020
WIRELESS
EMCORE’s Model 1997 uncooled, coaxial DFB laser offers a low-cost solution
for next-generation, wireless linear fiber optic links. The 1997 laser module
features extended bandwidth to 6 GHz and is optimized for 5G, DAS (Distributed
Antenna Systems) and small cells applications. It is designed to enhance
bandwidth and signal integrity for delivery of consistent, reliable wireless signals
in temperature-controlled indoor environments.
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’s long history of high-performance, leading-edge designs in
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.
