Frequency-Division-Muliplexed Coherent OTDR (FODTR-300)

The FDM-OTDR encodes multiple probe pulses at different frequencies, in the same time frame that conventional C-OTDRs send out a single pulse. This frequency-division-multiplexing enables larger data acquisition in the same measurement time compared to C-OTDRs. As a result the FDM-OTDR can achieve higher dynamic range with the same measurement time, or a significantly reduced measurement time with the same dynamic range.

    • High dynamic range >23dB (1)
    • 10 ~ 40 times faster measurement than conventional C-OTDRs
    • Characterize up to 12,000km long submarine optical cables
