New Lasers for Testing at CWDM Wavelengths

23 Sep 2015

Yenista Optics an established manufacturer of fiber optic test and measurement equipment announces the release of a series of laser modules for testing at CWDM wavelengths from 1270 nm to 1610 nm, plus additional modules at 1625 nm and 1650 nm. The CWDM modules correspond to the wavelengths used in 40 Gb/s and 100 Gb/s CLR4 and CWDM4 transceiver modules as well as conventional CWDM systems. The additional modules operate at supervisory channel and OTDR wavelengths.

Conventional CWDM sources are uncooled and can exhibit a drift of up to 6 nm in operating wavelength. This limits their use for test and measurement applications. Yenista’s new modules integrate into its OSICS platform and are stabilized in both wavelength and power. Stability is better than 5 pm and 0.01 dB for wavelength and power respectively. Output power for all modules is controllable from 0.2 to 10 mW.

Yenista’s Sales Director, David Heard commented, “We have been supplying tunable lasers for testing CLR4 and CWDM4 components. Until now, this has been the only option at these wavelengths. These new products provide a lower cost alternative, and in a platform that is already widely used in the industry.”

The OSICS platform will be showcased at the upcoming ECOC exhibition in Valencia, Spain from 27 September to 1 October 2015.
