CWDM DFB TOSA Pigtail Receptacle FC SC APC UPC Laser 1.25G 2.5G 1270nm to 1610nm CATV
Description
The Series are InGaAsP/InP CWDM MQW-DFB laser diode modules designed for WDM fiber optic communication systems. These modules have low threshold current and high performance at high temperature.
A laser diode is mounted into a coaxial package integrated with an InGaAs monitor PD and a single-mode pigtail.
