Gain 20dB Single Channel Pre-amplifier EDFA Optical Amplifier

Gain 20dB Single Channel Pre-amplifier EDFA Optical Amplifier for SDH NetworksSDH-EDFA-PA-G20 pre-amplifier designed for the Synchronous Digital Hierarchy (SDH) applications are single channel EDFA which are installed before the receiver to improve the receiving sensitivity,Website: , and extend signal transmission distance. The device features wide input power range from -35dBm to -25dBm, 20dB gain and low noise figure. It also includes RS-232 computer interface.This Rack mountable amplifier work by default in constant signal-gain mode, but they can be configured to constant total output-power mode. These units are used in long-hauls transmission applications, especially for PDH, SDH, SONET and optical Ethernet transmission application. Its ease-of-use and performance make the SDH-EDFA-PA-xx series the ideal solution for Access and Metro optical networks.Features• Service as a pre-amplifier C-Band 1550nm• Gain: 20dB• Wide input power range: -35dBm to -25dBm• Low loise figure: typical is< 4.5dB• Connectors: SC/UPC, SC/APC, FC/UPC, FC/APC, LC/UPC, LC/APC, ST/UPC and ST/APC connectors are available• Single or dual 110VAC, 220VAC, -48VDC, and/or 100V-240V power supply• Serial interface comes with RS232, RS485• 1U 19" rack mount structure for easy installation• All performance compatible with BellcoreGR-1312-CORE request• Use for Access and Metro optical networks• Works with point-to-point applications• High stability and reliability• 3 years warranty• 10 years of operation life• OEM is availableHighlights• Hot Swap Network Management Agent• SNMP network management interface: RJ45• Support Telnet for optional• ASE noise filter & ASE suppression filters• High Precise ACC (automatic constant current) Circuit as default, if you need other circuit, please contact at sales@fiberstore.com• ATC (automatic temperature control) function• Offering status appearance and diagnosing fault with LCDMechanical StructureStructure ExampleNOTE:The SDH EDFA from Fiberstore including 1+2+3.SpecificationsParametersSymbolMinTypMaxUnitOperation Wavelengthλc153015501562nmSaturated output power (1)Po  20dBmInput power (2)Pi-35 6dBmGainG 2032dBNoise FigureNF 4.5 dBInput IsolationISOi30  dBOutput IsolationISOo30  dBInput pump leakagePumpLin  -35dBmOutput pump leakagePumpLout-45 -45dBmReturn LossRL  -45dBPolarization Dependent GainPDG  0.3dBPMDPMD  0.5psOperation TemperatureTw-5 60℃Storage TemperatureTs-40 80℃Humidity (3) 10 85%Power VoltageVps85/170110/220132/264VACPower ConsumptionP  18WSerial interfaceRS232, RS485Power supply110VAC, 220 VAC, -48VDC, or 100V-240VConnectorsSimplex SC/UPC, SC/APC, FC/UPC, FC/APC, LC/UPC, LC/APC , ST/UPC and ST/APC availableWarranty3 years(1): Customer optional(2): Pre-Amplifier: input power –35~-25dBm; Inline-Amplifier: input power –25~-10dBm, Booster: input power –10～+6dBm(3): No condensation
