ST810 DUAL WAVELENGTH LASER SOURCE ST810 Dual Wavelength Laser Source can be used in every kind of fibers such as the LAN (Local Area Network), broadband network, city area network, CATV network or long-distance fiber network and so on. It is made according to the laser emission and disposal technique, and it can provide steady light signal. It can be used to distinguish fiber, measure the wastage of fiber accurately, check the continuity and help to evaluate the transfer quality of fiber link through using with series of optical power meter of ST800. It provides high quality laser lamp-house for field test and development in laboratory.
