Light Source is a handy instrument to provide you several wavelengths for testing the fiber equipment in an optical network and FTTx construction. Light Source is ideal for field or laboratory testing of optical communication systems at 850nm / 1300nm for datacom testing, 1310nm / 1550nm / CWDM 1270nm ~ 1610nm ( 20nm spans ) for all WDM testing , as well as 1490 nm for FTTx testing by changing the interchangeable SFP module. Light Source features zero warm up, superb productivity and is easy to use with its pocket-size and rugged handy design.

With a LC / SC patch cord, the Light Source can be used for most widespread fiber interfaces such as LC / ST / SC / FC connectors. It is suitable to test both Singlemode and Multimode cables.

Internally there is a specially designed power circuit called APC (Auto Power Control). The APC circuit provides continuous power which avoids unstable laser output when the battery is low.

The LD output signal can be switched between Continuous Wave (CW) or Pulse Mode 270Hz / 2KHz Modulated Mode to simulate signal transmission. There is a dust proof cap which will prevent dirt from getting into the LD connector. The cap also helps avoid accidental exposure to the laser beam into your eyes.
