    Description

    The DWDM EDFA power amplifier is a low-noise, gain-flat C-band erbium-doped fiber amplifier (dwdm edfa c-band), which cost-effectively extends the optical link power budget to build long-haul DWDM solutions. The EDFA can be used as dwdm EDFA booster or pre-amplifier dwdm edfa.
    The dwdm edfa amplifier are made up of high stability Pump Laser and unique ATC (automatic temperature control) and AGC (automatic gain control) circuit, which are the key components to ensure the high stability and reliability of output power. The unique optical circuit design ensures the excellent optical characteristics. The high stability and high precision MPU system are employed to ensure the control adjustment and display are intelligent and user-friendly.

    Professional design GFF (gain flattening filter) with excellent optical path design make flatness and noise reach the best optimization. It can provide 40~80 channels, and flatness above 35nm.

    The optical circuit is designed especially for digital optical fiber communication system including:

    (1) lower noise figure

    (2) the high output booster and high sensitivity pre-amplifier improve the system loss budget

    (3) Broad input power range and output power is adjustable easily.

    The design of dual Power Mixed and hot swap provides longer MTBF. Also, the power system can be backed up.

    Employing the intelligent temperature control system, the fan is on when the module temperature over 35℃, and it will stop when the temperature goes under 30℃, which ensures the dwdm edfa amplifier high thermal stability and fan’s long lifetime, moreover, the professional air flow design can also ensure the best temperature stability.

    The DWDM EDFA has intelligent network management system. Perfectly network interface: Ethernet, RS-485 and RS-232 network interface, and the open mib ensure the connectivity with all other network management systems.

    Features

    This Single Channel dwdm EDFA has the following features:

    ➢ Low noise figure: typical is under 4.5dB

    ➢ High Flatness: Typical 1.5dB

    ➢ Redundancy hot swap power module: 110/220VAC and -48VDC can plug mix

    ➢ Works for 19’ or 21’ racks

    ➢ Cover Whole C-Band: Carrier 40 or 80 chs

    ➢ OLED display shows and controls the system parameters, LED status indication shows the alarm status

    ➢ Supports ETH, RS232 ports by RJ45

    ➢ Network Management interface supporting SNMP via Ethernet port

    ➢ AGC(Automatic Gain Control)optical output
