Yenista Adds O-Band Tunable

LANNION, France -- Yenista Optics, a leading manufacturer of fiber optic test and measurement equipment, announces the release of a new tunable laser in the 1310nm wavelength region. The T100 model uses a new optical cavity design to provide high optical power (+6dBm) with extremely low noise (>80dB/0.1nm SSER).

The combination of high power and low noise output has not been possible with conventional tunable laser designs. Yenista is the first company to overcome this limitation with its patented self-filtered external cavity laser technology. The technology is used in its Tunics T100 models. The new O-band version operates from 1270nm to 1340nm with up to +6dBm output power and a signal to spontaneous emission ratio (SSER) of over 80dB/0.1nm. The laser is particularly suitable for characterizing narrow bandwidth filters and as a light source for testing high speed transmission systems.

“The original or O-band, operating around 1310nm, has been widely used for short reach telecom applications. It corresponds to the low dispersion region of standard single mode 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.”
