Description
The D1861D direct-modulated laser (DML) module is
a cost-effective solution for 10 Gbits/s digital trans-
mission up to 50 km using traditional intracity
SMF-28
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, thermoelectric cooler, thermistor, optical
isolator, and a rear-facet monitor photodiode, which
allows for external optical power control.

Pin Information
1. Laser anode is case ground mAp-p drive current.
2. A positive current into this pin cools the laser.
