Customized board-based DVS module



Overview
The customized DVS module is suitable for customers with specific requirements for the chassis size. We can design the DVS module based on the chassis size provided by the customers. By integrating the optical path hardware of the distributed optical fiber vibration DVS system and the DVS acquisition card, and outputting signals through Gigabit Ethernet, the module is small in size and suitable for use in customized equipment such as fiber optic monitoring systems and optical cable locator instruments.

Characteristics
  • Customized requirements: Customized design based on the customer's chassis size.
  • High integration (UNL, AOM, EDFA, BPD, capture card)
  • Output of vibration data information via gigabit network interface
Application
  • Optical cable monitoring equipment
  • φ-OTDR system
  • DVS Distributed Vibration Monitoring
  • Optical cable locator, portable device

Mechanical dimension drawing

The following is the dimension drawing of the integrated module. The overall size of the module is 190*150*33mm. It does not include connectors and optical fibers. To ensure the heat dissipation performance of the module, a good ventilation environment should be ensured when installing the module. For the optical fiber flange and coaxial connector, please use the corresponding protective caps when not in use to prevent the connectors from getting dirty.
