II-VI Inc unveils 800mW high-reliability pump laser for next-gen undersea networks

Engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA has unveiled new high-reliability pump lasers for next-generation undersea networks, offering what is claimed to be the highest commercially available output power of 800mW, with record electrical-to-optical conversion efficiency enabling a significantly lower cost per bit of undersea transmission.

Specifically:

With 800mW of output power available, II-VI enables higher-capacity cables, including the trend towards higher-fiber-count designs and wider transmission windows across both the C- and L-bands.
The combined efficiency gain from all the pump lasers across the span of the cable reduces the energy required to operate undersea systems and lowers power cable costs.
The high output power and energy efficiency of the pump lasers enable the reach extension of undersea links, which are constrained by maximum power feed limits.

“The growth of hyperscale data-centers and internet traffic worldwide is driving the buildout of the global undersea network infrastructure and spurring the demand for our high-reliability 800mW pump lasers,” notes Simon Loten, general manager, II-VI Pump Laser Division. “This demand will continue to be strong globally, especially in the regions of emerging economies where a growing number of data-centers will be required to handle the exponential increase in user and device connectivity.”

In booth #4312 at the Optical Networking and Communication conference & exhibition (OFC 2019) in San Diego, CA, USA (5-7 March), II-VI is showcasing new products enabling applications including 5G optical infrastructure, hyperscale data-centers, 3D sensing and LiDAR.
