Edfa - Holar Network Co.,Ltd

1550nm EDFA,optical fiber amplifier

The HHGA-1550 optical fiber amplifier, uses the world-famous company mature 1550nm modulation technology. Core part all by the US original installation, had guaranteed product high grade and redundant reliability. As a result of the manufacture domestically, may reduce the network large scale for the user the cost of investment, and may obtain the consummation post-sale service.

This aircraft built-in consummation reliable luminous power output stabilizing circuit and the laser thermoelectricity cryostat temperature control control circuit, has guaranteed the complete machine optimum performance and laser's long life steady work.

Characteristics

This aircraft's light module pump laser and the er-doped optical fiber original installation import by the US.

This aircraft is equipped with the consummation reliable luminous power output stabilizing circuit and the laser thermoelectricity cryostat temperature-control circuit, has guaranteed the complete machine optimum performance and the laser long life steady work.

In this aircraft supposes the microprocessor software, has the laser condition monitoring, the digit demonstrated that fault warning, network management and so on many kinds of functions. Once laser's operational parameter deviation software establishes permission scope, automatic cutout laser power source. The red candle twinkle, prompts reports an emergency, digital kneading board prompt breakdown reason.

This aircraft micro processes the software to provide RS-232 and 485 connections, uses in the network management and the long-distance monitoring.

This aircraft uses 1RU 19 " the standard rack, the highly effective switching power supply, is suitable the 85~254V city electricity.
