Handheld Type Variable Optical Attenuator

Introduction: Our company’s handheld type VOA can make optical single have continuous

variable attenuation. The main purpose of this kind of attenuator is to test laser system online, so

this attenuator can applied to PDH, SDH and CATV system.

Applications:

Telecommunications project maintenance

CATV project and maintenance

Integrated wiring system

Optical components production and research

Optical communication’s teaching

and experiment

Other fiber project
