Alphax LD temperature characteristic testing system

High-performance LD temperature characteristic testing system in accordance with the former Bellcore (present Telcordia) standards.

Alphax LD temperature characteristic testing system

  • Industry-standard machine acknowledged by users all around the world.
  • Efficiently conducts characteristic tests between -40 °C and +85 °C which satisfy the former Bellcore (present Telcordia) standards for optical communication systems.
  • A large number of units have been delivered not only for communication LDs but also for recording LDs (350 nm - 900 nm).
  • By changing the work holders, various types of element shapes can be supported.
  • Water cooling Peltier control is adopted for the temperature control system, and the temperature is controlled precisely within the range between -40 °C and +95 °C.
  • Measures electrical and optical characteristics of LDs (I-L, I-V, FFP, λ) automatically.
  • Increases and reduces the temperature of 160 elements simultaneously to minimize losses when the temperature is stabilized.
  • The measuring time is within 120 minutes at three temperatures (+25 °C -> +95 °C -> -40 °C -> Normal temperature) x I-L/λ (W/O-FFP).
