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.
Features
s Direct-modulated 1310 nm laser module character-
ized for use in 10 Gbits/s operations up to 50 km
s Average optical output power, 4 mW min.
s Temperature stabilized with internal thermoelectric
cooler (TEC), enabling operation within a wide
temperature range of –40 °C to +80 ° C
s Hermetically sealed optics, isolator on TEC
s GPO* RF connector
s Single-mode fiber pigtail
s High relaxation frequency at low bias
Applications
s SONET/SDH low-cost metro applications
s High-speed data communications
s DWDM equipment drop-side applications
