25Gbps DFB laser targets mobile networks

August 08, 2016 // By Julien Happich
Mitsubishi Electric is now shipping a 25 Gbps distributed feedback (DFB) laser diode for optical transmission at 1310nm between base stations and central offices in radio access networks within mobile telecommunication systems.

The 25 Gbps DFB laser diode (part number ML764AA58T) comes in a 5.6 mm TO-CAN package and operates in a temperature range of -20 to +85ºC. Transceivers incorporating the new DFB laser can operate outdoors without a cooling system. The device's simple structure helps satisfy the SFP28 standard for 25 Gbps compact transceivers.
