Strictly control multi-mode EF (Encircled Flux), adaptable to different types of light source injection
Due to the different encircled fluxes when different multi-mode lasers transmit within the optical fiber, there will be significant errors
in the calibration data of the attenuator without calculating EF. Dimension Technology’s multi-mode attenuator, through the mode
controller and strict encircled flux detection equipment, strictly controls the EF within the standards of IEC-61280-1-4 and
TIA-455-203, ensuring good testing accuracy under the injection of different light sources.
Test results after optimization: attenuation linearity ±0.10dB
Ultra-low insertion loss and ultra-fast attenuation speed
The next-generation programmable optical attenuator, through optical path structure optimization, has achieved a further reduction in insertion loss (SM<1.0dB, MM<2.0dB). At the same time, the optimized design structure can meet higher attenuation rate requirements. The rate of mechanical attenuators has been upgraded from 25dB/s to 50dB/s, with full-range attenuation in 1.2 seconds; MEMS attenuators have been increased from 1000dB/s to 2000dB/s.
Built-in power monitoring with semi-open loop detection, controlling attenuation in three modes
To accurately measure the power value after attenuation, POA has added an optional optical power meter component after the
attenuation optical path, monitoring the optical path attenuation in a semi-open loop. With the addition of the power meter, real-time
feedback adjustment is made in power monitoring mode, achieving an attenuation accuracy of ±0.10dB.
The all-new generation of attenuators has been designed with three control modes to cater to different application scenarios and meet various needs:
Programmable support for remote control and automatic testing, platform + modular design
For users with a high degree of automated integration in their testing systems, Dimension’s new generation of programmable optical attenuators offers various remote control methods, including API interfaces, control commands encapsulated in LabVIEW statements, and OMEGA client software, etc., to help users quickly embed into the testing system.
For use cases in laboratories and universities, providing a setup interface on visual software makes it more convenient for users.
Therefore,Dimension Technology offers a highly customizable automatic attenuation task feature, allowing for quick test task setup.
