York Fiber Ltd. disclosed two new types of erbium-doped fiber amplifiers. The DF1500A erbium-doped fiber amplifier is designed for optimal gain bandwidth applications. It is co-doped with aluminum and is intended for use in broadband optical networks and cable television. The gain of this type of fiber The bandwidth is greater than 35nm, the new manufacturing technology to improve the pump efficiency, the gain efficiency value is greater than 3.5dB / mW. The DF1500E fiber has a gain efficiency value of greater than 6 dB / mW, the highest reported in commercially available optical fibers whose pump-to-signal conversion efficiency is close to the quantum limit and DF1500E
