  • FWA-1550G series is a Pre-amp DWDM EDFA ,Input power:-30~ -15dBm,Fixed output:-5~10dBm, realizing gain flatness ( ≤±0.5dB) at gain spectrum <1.0dB within whole C-band, FWA-1550G series Gain EDFA adopts the world's top class pump laser and America OFS erbium-doped optical fiber. Perfect  APC, ACC and ATC control, excellent design in the ventilation and heat-dissipation ensure the long life and high reliable work of pump laser. The LCD at the front panel offers the work index of all equipment and warning alarm. The laser will switch off automatically if optical power is missing, which offers security protection for the laser。


    Application

    (1)DWDM Line amplify  (2)DWDM Pre-amplify   (3)DWDM Power amplify   (4) Optical distribution system (5) SDH, ATM long distance transmission (6) Video, Ethernet optical transmission system ,etc.





     High quality: The former-class pump commonly use 980nm, after-class pump use 1480nm, power is legitimately optimized by software to minimize the NF of the EDFA. It can make the system to obtain superior CNR. 
     Reliability: Reliability: The 19 "1U standard rack, built-in high-performance switching power supply,it can work at 85 ∽ 265Vac City Network Voltage, As well as an optional DC48V power supply (reservations required); chassis cooling automatic temperature control.
     Intuitive: The laser is the most expensive machine components, machine equipped with microprocessor monitors the working state of the laser, the panel LCD window displays the operating parameters. 
     Network type: Select All-piece status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standard, it enable network management monitoring capabilities.
     Power plug: Aluminum structure using Plug-in type switching power supply, allows for heat dissipation and replacement. And dual power supply hot and cold backup.
