CWDM DFB Laser Source
The Optilab DFB-CWDM series are multi-band CWDM Distributed Feedback (DFB) laser sources that incorporates up to 9 DFB lasers. They are designed for general laboratory and device testing applications. The DFB-CWDM is a reliable and cost effective DFB laser source for providing up to 8 different CWDM DFB wavelengths on a single output fiber. The CWDM DFB laser drive current are precisely controlled to ensure constant output power.The DFB-CWDM can be easily configured in 3 different ways. First, all 8 CWDM channels can be combined into on multiplexed output. Second, any CWDM channel can be dropped from the combined spectrum. Third, each of the CWDM channels can be accessed independantly via the front panel adaptor.
