Import Edfa Optical Amplifier — Buy in wholesale FOB from Supplier in China

EDFA Optical Amplifier module provide multi-function, low noise, Erbium-Doped Fiber Amplifier (EDFA) solutions, The amplifier module can be operated at constant gain (Automatic Gain Control AGC), constant output power (Automatic Power Control, APC). Integrated VOA can be automatically adjusted to achieve smooth gain spectrum. It can amplify the C-Band signal with or w/o middle stage access (MSA), which brings great flexibility for the network application. C-band optical signal overall amplification Covering the wavelength range of 1528 ~ 1565nm Support systems to achieve different cross-section radio repeater transmission Wide operating wavelength range:1528nm~1565nm Three Optical Amplifier C-Band applications: Booster ï??n-line Pre-amplifier Low noise figure: typical: 5dB Excellent gain flatness Multiple operating modes: AGC adjustable Gain APC output is adjustable ACC voltage adjustable Mid-stage access for DCM or OADM Optional OSC channel for remote management MON port, on-line monitoring optical power and OSNR Many model options serve all the traditional amplifier applications in an extended optical link: booster, in-line, and pre-amplifier. A booster amplifier operates at the transmission side of the link. It features high input power, high output power, and medium optical Gain . Boosters are designed to amplify aggregated optical input power for reach extension. An in-line amplifier operates in the middle of an optical link. It features medium to low input power, high output power, high optical Gain , and a low noise figure. In-line amplifiers are designed for optical amplification between two network nodes on the main optical link. A Pre-amplifier operates at the receiving end of an optical link. It features medium to low input power, medium output power, and medium Gain. Pre-amplifiers are designed for optical amplification to compensate for losses in a demultiplexer located near the optical receiver. Some EDFA Models include an additional mid-stage port designed for insertion of a Dispersion Compensation Management (DCM) unit without its inherent insertion loss. The design of these models maximizes the DCM benefits to increase deployment flexibility. New placement options require fewer amplifiers in the link, and they can open the door to applications that were not possible with older technology. Some EDFA Models include a Red and a blue port designed for Single fiber DWDM Solution. The design of these models is used for single-fiber DWDM transmission systems.
