Highly reliable pump laser sources, a key component for use in Erbium Doped Fibre Amplifier (EDFA) applications. A broad range of cost effective 980nm pump laser solutions can be offered to satisfy any requirement in today's demanding market. These range from high power cooled butterfly pump lasers, which can be used in tight tracking applications to eliminate the need for an external monitoring circuit, to un-cooled MiniDILs - ideally suited for single channel applications - which offer very low power dissipation in a small form factor package. The Lumics pump has a proven track record in reliability demonstrated in the field with over 30 million device hours accumulated.
