Variable attenuator MOA-3800

Two versions of the MOA-3800 exists: singlemode and multimode. Optimized for use with EXFO systems and software, the MOA-3800 Variable Optical Attenuator (VOA) can add precise attenuation to four, eight or sixteen different singlemode or multimode fibers (each fiber can be set independently). An optional self-adjusting mode is also available, which automatically monitors and sets the output power to the desired level. With its remote control capabilities using Standard Commands for Programmable Instruments (SCPI) over Ethernet, the MOA-3800 is the ideal solution for the following applications: bit error rate (BER) testing system characterization component or system loss simulation optical margin analysis WDM power balancing Singlemode KEY FEATURES Optimized for singlemode fiber use Wide attenuation range up to 40 dB Protocol and bit rate independent 4, 8 or 16 channels housed in 1U SCPI over Ethernet remote control Available with VOAs only, or with a self-adjusting power option Linear response Multimode KEY FEATURES Optimized for multimode fiber use Stable attenuation, independent of mode fill condition Protocol and bit rate independent 4, 8 or 16 channels housed in 2U SCPI over Ethernet remote control capabilities Available with VOAs only, or with a self-adjusting power option Linear response
