edfa optical amplifier

 is a high power multi-output optical fiber amplifier with a gain spectrum
bandwidth of 1535~1565nm. It is mainly designed for CATV or 1~8 continuous strip channels (ITU wavelength) applications.
It provides a flexible, low-cost solution for large-scale FTTH coverage of CATV systems in large and medium-sized cities.
WS-56EYAxx can achieve single-wavelength cable TV transmission, CWDM single-fiber three- wave, flat-gain type, DWDM;
its reliable and excellent performance ratio between the main application of FTTH, FTTB, DBS, MMDS, FTTX pon, is to build CATV large Medium-sized optical fiber transmission network is an important equipment.

1. Adopts world top brand pump lasers and the OFS fiber of United States, advanced LG switch low-power circuit design, greatly reducing the overall power consumption and heat.
2. Perfect APC, ACC, ATC control, users use in different networks, good ventilation design and temperature-controlled fan, ensure the long life and high reliability of PUMP laser.
3. Using digital control chip, remote or local output power adjustable.
4. Excellent protection circuit design, with light detection, optical return loss monitoring. Great protection of lasers and light path safety.
5. Built-in low-noise preamplifier eliminates the need for cascaded EDFA, allowing input light to be as low as -5dBm, greatly reducing CNR and MER degradation.
6. Demultiplexer for 1310/1490/1560nm EPON and GPON. It greatly facilitates network applications with PON. Low noise figure (type ≤ 4.5dB, Max ≤ 5.0dB);
7. The total output optical power is optional: 2-10W (33-40dBm);
8. The front panel can be removed and replaced flexibly according to the number of output ports; Can add a built-in optical switch module to facilitate the expansion of the device function; Cooling fan supports online replacement;
9. The front panel LCD provides the operating parameters and alarms of the entire unit. RJ45 provides serial communication and SNMP network management interface; Carrier-grade dual power hot backup, CPU assignable power.
