Coaxial/Butterfly 18-Channel DFB Light Source Wavelength Can Be Customized

   U8120/U8130 Multichannel DFB laser source offer superior performance for the testing of CWDM, DWDM components, AWG & PLC components, optical amplifiers, and other general purpose fiber optic test and measurement applications. It is specifically designed for high volume CWDM, couplers and PLC prodUtion line application.

   U8120/U8130 Multichannel DFB laser source is a high stability, compact-sized, fast-starting, and affordableoptical laser source. It provides Multichannel high performance, fixed wavelength output. Any two or four and more of the following channels can be provided on request: 850, 980, 1250, 1270, 1290, 1310, 1330, 1350, 1370, 1390, 1410, 1430, 1450, 1470, 1490, 1510, 1530, 1550, 1570, 1590, 1610, or 1625 nm and etc.

   DFB(Distributed Feedback Laser) laser, that is, distributed feedback laser, is different in that Bragg Grating (Bragg Grating) is built-in, which belongs to side-emitting semiconductor laser. DFB lasers are mainly based on semiconductor materials, including gallium antimonide (GaSb), gallium arsenide (GaAs), indium phosphide (InP), zinc sulfide (ZnS) and so on. The biggest feature of DFB laser is that it has very good monochromism (that is, spectral purity), its line width can generally be within 1MHz, and it has a very high side mode rejection ratio (SMSR), which can be as high as 40-50dB or more.
