1290 nm to 1610 nm DFB-LD, DFB Laser (DFB-CWDM)

Data Sheet

The DFB-CWDM is a CWDM Coaxial DFB-LD Module for CWDM analog communication, CATV return-path, laboratory instrument, and R&D applications.

Product Overview

The DFB-CWDM is a CWDM Coaxial DFB-LD Module for CWDM analog communication, CATV return-path, laboratory instrument, and R&D applications. Formerly known as the LDM5S513, this cost-effective, high stability DFB laser chip has a selectable wavelength with range between 1290 nm to 1610 nm. The versatile DFB-CWDM also features a built-in InGaAsP monitor photodiode, built-in optical isolator and 4-pin coaxial pigtailed package, single mode coupling, and an FC/APC connector.
