PRODUCTS - FIBRE OPTICS - ERBIUM DOPED FIBRE AMPLIFIER
The Benchmark ETS is an EDFA (Erbium Doped Fibre Amplifier) Training System. Erbium Doped Fibre Amplifier (EDFA) is an optical amplifier that amplifies optical signals sufficiently enough to cover several tens of kilometers without any need for conventional repeaters. Moreover, as it works in the same optical domain, it avoids the need for several stages of signal conversion with their associated problems. Consequently, EDFA finds extensive use in the fibre backbone.
The Benchmark ETS - EDFA Training System - addresses the need for a training setup that shows the building blocks of a typical EDFA as well as the characteristics of such blocks. All the blocks are given with proper input and output connections such that they can be configured in different modes of operation, such as co-directional and counter-directional operations. This modular approach also facilitates study of individual block characteristics wherever possible.
