II-VI unveils 1W 980nm Pump Module
II-VI Incorporated has launched a high-power, 1 watt, 980nm pump laser module, based on high-reliability laser diode technology from its in-house wafer fab in its Laser Enterprise Division in Zurich, Switzerland.
"This advancement in pump laser technology delivers the most efficient commercially available 980 nm pump laser in the world, both in terms of laser conversion efficiency and total module power consumption. It provides EDFA designers with new options to increase output power per stage within high-power DWDM solutions, while being more efficient and reducing overall cost of network ownership," said Simon Loten, GM of the II-VI Pump Laser Division.
"The new module can also be used to replace pairs of lower power modules, enabling cost-effective, more thermally efficient and environmentally conscious designs. When compared with 14xx nm and competing 980nm solutions, the II-VI pump laser modules achieve very high power at significantly lower drive current and thermo-electric cooler power."
According to the company, the new 1W pump laser module enables up to 1050mW of kink-free optical power through a grating- stabilised single-mode fibre for easier integration into the EDFA system. The module is housed in the established 10-pin, mBTF (mini-Butterfly) format package which is quickly becoming adopted as the new market standard, providing an electrically and mechanically compatible pinout to legacy 14-pin packages, in a 75 percent smaller package.
The product is fully qualified to the requirements of Telcordia GR-468-CORE and is RoHS 6/6 compliant. The 1W module is sampling to customers now, and will be ramping through the third quarter of 2015.
