DL-53X8AR-CXX0 Series
Uncooled 1470 ~ 1610 nm CWDM MQW-DFB LD for CATV return path application
****************************************************************************************************************************************************************
DESCRIPTION
DL-53X8AR-CXX0 series are designed for coupling a single mode optical fiber with 1470 ~ 1610 nm
CWDM MQW-DFB uncooled laser diode. DL-53X8AR-CXX0 series are the best kits as light source for
CATV return path application.
