12/08/2011 - New OSICS Module, the Variable Back Reflector

Yenista Optics, a leading manufacturer of fiber optic test and measurement equipment, has further expanded its multi-channel OSICS platform with a new Variable Back Reflector module. The "OSICS BKR" module provides a controllable back reflection of up to 55dB over the 1250 nm to 1650 nm wavelength range.

Back reflection or return loss is an intrinsic parameter in all optical systems which occurs as a result of Rayleigh scattering in optical fibers and due to the mismatch of refractive indices within optical components. Poor or open connectors are also significant contributors. Managing return loss and testing components and systems under a range of operating conditions is an important part of system design and validation. The "OSICS BKR" provides a simple solution. Further, it can be integrated with other test instruments such as light sources, optical switches and variable attenuators as part of the multi-channel OSICS platform. The modules can be controlled either manually or via the GPIB and RS-232 interfaces.

David Heard, Sales and Marketing Manager commented, "The OSICS platform is widely used throughout the fiber optics industry. Adding additional modules provides our customers with a cost effective upgrade without changing the platform and control software with which they are familiar. The module is particularly useful to stress transceivers for return loss sensitivity measurements and for PON system testing where open connectors are an issue."

 
28/02/2011 - Yenista Sets the Standard with New O-Band Tunable Laser

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

"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 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 Nicéphore 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."
