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.
