Subsea optical network component and module specialist II-VI Inc has unveiled an 800 mW high reliability pump laser product line for next generation undersea networks. According to II-VI, its undersea pump lasers achieve the highest commercially available output power of 800 mW, with record-high electrical-to-optical conversion efficiency, enabling a significantly lower cost per bit of undersea transmission.


IV-II lists the specific attributes of its lasers as:

  • ith 800 mW of output power available, they enable higher capacity cables, including accommodating the trend towards higher fibre-count designs and wider transmission windows across both the C- and L-bands
  • The combined efficiency gains from all the pump lasers across the span of the cable reduce the energy required to operate undersea systems, and lower 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 datacentres and Internet traffic worldwide is driving the buildout of the global undersea network infrastructure and spurring the demand for our high reliability 800 mW pump lasers,” said Simon Loten, general manager, II-VI Pump Laser Division. “We expect that this demand will continue to be strong globally, especially in the regions of emerging economies where a growing number of datacentres will be required to handle the exponential increase in user and device connectivity.”
