  • Diagram
  • 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 1310/1490/1550nm EPON and GPON. It greatly facilitates network applications with PON. Low noise figure (type ≤ 4.5dB, Max ≤ 5.0dB);

  • The total output optical power is optional: 2-10W (33-40dBm);

  • 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;

  • 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
