AVARA TECHNOLOGIES. EDFA - Erbium Doped Fibre Amplifier

The Avara OptoHopper series of optical amplifiers are designed for use in long haul PDH, SDH or SONET optical transmission systems.

The OBA series of booster amplifiers are installed after the optical transmitter to increase transmission distances for single wavelength optical transmission systems.

The OBA series are Erbium doped fibre amplifier (EDFA) providing optical output power up to 18dBm for long haul applications. The OBA series is designed for use in SDH transmission applications and has been specifically designed to integrate with Ericsson / Marconi SDH product range.

The programmable output power level provides flexibility in network design allowing spacing between SDH nodes to vary.

Management of the OBA amplifiers is provided through an easy to use web based management interface. The OBA is rack mountable in 19”, 21” and 23” rack sizes.
