Yenista Optics has released a new tunable laser for applications in the O-Band (1310-nm) wavelength region. The T100 model uses a new optical cavity design to provide high optical power with low noise, according to the company.
The combination of high power and low noise output has not been possible with conventional tunable laser designs, Yenista asserts. However, the company says its patented self-filtered external cavity laser technology overcomes conventional limitations.
The new T100 O-band laser operates from 1270 nm to 1340 nm with up to +6 dBm output power and a signal to spontaneous emission ratio (SSER) of over 80 dB/0.1 nm. 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-band, operating around 1310 nm, has 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.”
Yenista will be demonstrating the Tunics T100 lasers at the upcoming OFC/NFOEC exhibition at the Los Angeles Convention Center, March 8-10, booth 1113.
