IPG's EAR Series are high-performance Erbium-doped Fiber Amplifiers (EDFAs) that supply maximum output power and port count while using minimal space. IPG’s cooler-free pumps assure superior reliability with low power consumption. The integrated CWDM splitter option eliminates the need for a separate shelf, reducing component count, lowering the FIT rate and improving system performance. IPG's EDFAs have a broad input power specification and can be cascaded within a single equipment rack to support long-term housing growth. A lower power 1RU version is available; both EDFAs are designed and manufactured using IPG’s high-reliability pumping technology.
