ODS–2200 Analog Fiber Optic Data Acquisition System

This latest addition to the ODS range of EMP/EMC links extends the operating bandwidth to 2.4GHz (typical) whilst still retaining all of the functional features of the original ODS–1800.   The ODS–2200 has been completely redesigned to incorporate:

  •  New amplifier designs for improved bandwidth and bandpass flatness

  •  New switching technology to significantly increase the isolation between all 8 transmitter inputs

  •  Slightly reduced transmitter form factor

  •  New battery retention latch for quick battery attachment and release

  •  Fiber optic connectors changed to duplex SC type, with an EMI shielded duplex SC type panel adapter
