1550nm Erbium Doped Fiber Amplifier ZOA1550HW
ZOA1550HW series high power single mode EDFA is characterized with low noise, high linearity. Build-in well-performed CWDM integrated 1490nm /1310nm data stream from the OLT and ONU into single fiber transmission through EDFA, reducing component count and improve system performance and reliability. It offers a flexible, low-cost solution for CATV large area coverage of metropolises and medium-sized cities.
ZOA1550HW series is equipped with completed APC, AGC, ATC control, excellent design for heat-dispersion which guarantees long time working and stable operation of the PUMP laser. RJ45 on the back panel offers SNMP network interface. The wide LCD displays all the parameters of the whole unit and alarming. The laser will be automatically switched off if optical power is missing; it offers security protection for the laser. All of the optical outputs are located on the front panel (can be on back panel is customer specify). ZOA1550HW series adopts single mode pump, EDFA and multi-pumps integration technique. Optimized for low noise, allow for clear transmission of video, voice and data signals. Its noise figure and reliability is much better than Double-clad Yb/Er Amplifiers.
1RU chassis, total output power >1000mW, 8 uplink optical ports, for OLT+8 1550nm output optical port, multiply 1310/1490 data stream.
2RU chassis, total output power >4000mW, max. 32 uplink optical ports, for OLT+32 1550nm output optical port, multiply 1310/1490 data stream.
Features
(1) High quality: the former-class pump adopts 980nm as small signal to amplify, after-class adopts 980nm high power multi-mode pump, optical power is optimized by software to minimize noise figure of EDFA, and make systems achieve excellent CNR.
(2) Flexibility: 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. Mechanical cooler (Dual fans) on back panel helps to make heat dispersion thus to protect the pump laser
(3) Intuitive: The machine equipped with microprocessor monitors the working state of the laser, the panel LCD window displays the operating parameters.
(4) Network type: Select All-piece status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standard, it enables network management monitoring capabilities.
(5) CWDM: Build-in well-performed CWDM integrated 1490nm /1310nm data stream from the OLT and ONU
