The DFB-CWDM-TO is a CWDM TO Can DFB-LD Module for CWDM analog communication, CATV return-path, laboratory instrument, and R&D applications. Formerly known as the LDT5S51X, this cost-effective, high stability DFB laser chip has a selectable wavelength with range between 1290 nm to 1650 nm. The versatile DFB-CWDM-TO also features a built-in InGaAsP monitor photodiode, built-in optical isolator and 4-pin TO Can, and a flat window emission type. Contact Optilab for more information.
