Optical amplifier WS-57EYA2U

adjustablehigh-powertransmission

The WS-57EYAxx series high power 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-57EYAxx 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. 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. 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. Using digital control chip, remote or local output power adjustable. Excellent protection circuit design, with light detection, optical return loss monitoring. Great protection of lasers and light path safety. 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. Demultiplexer for 1310/1490/1560nm EPON and GPON. It greatly facilitates network applications with PON. Low noise figure (type ≤ 4.5dB, Max ≤ 5.0dB);
