The LS-215-G optical Light Source is a small size low cost item which fulfils all necessary technical field equipment requirements. Available of working wavelengths 850/1300 for multimode or 1310/1550 nm single mode applications or a visible 650 nm laser source. The rechargeable battery ensures long term working with a minimum life time of 2 years. Batteries can be charged via a USB port or external AC/DC adaptor. The universal output port allows the easy installation of optical adaptors FC, SC, ST or LC widely used in telecommunications, data and industry networks. The output port is designed for connection of PC polished connectors. The LS-215-G light source can be used in cooperation with the PM-215, the same smallest design optical power meter for measurement of Insertion loss and evaluation of power budget in optical networks.  The tester is equipped with USB port – for battery charging and for PC control.
