D1861A 10 Gbits/s 1310 nm DML Module
Description
The D1861A direct-modulated laser (DML) module is
a cost-effective solution for 10 Gbits/s digital trans-
mission up to 50 km using traditional intracity SMF28
single-mode fiber links. The 1310 nm wavelength
eliminates the need for concern about dispersion
control over most installed intracity fiber plants. The
package contains a high-speed DFB laser chip, ther-
moelectric cooler, thermistor, optical isolator, and a
rear-facet monitor photodiode, which allows for exter-
nal optical power control.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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. RF input shall be ac coupled. It is recommended that a series induc-
tor of 100 µH be placed external to the device on Pin 3.
