Yenista offers O-Band tunable laser

The combination of high power and low noise output has not been possible with conventional tunable laser designs, Yenista asserts. The laser is particularly suitable for characterizing narrow bandwidth filters and as a light source for testing high-speed transmission systems, Yenista says.“The original or O-bandhas been widely used for short-reach telecom applications. It corresponds to the low dispersion region of standard singlemode fiber but is limited to non-amplified links by the lack of optical amplifiers. With the demand for higher capacity in access and data networks there is now a resurgence of interest in this wavelength band.” said Nicephore Nicolas, Yenista’s sales and marketing manager. “Engineers developing and testing components for the latest 40- and 100-Gigabit Ethernet and FTTH/PON networks really benefit from the performance of Yenista’s Tunics T100 lasers.”
