High performance OTDR module for RFTS(Remote Fiber Test System)

The AQ7277 and AQ7277B are OTDR modules for RFTS (Remote Fiber Test System) including features required for monitoring fibers.

-High-speed data transfer

  The Ethernet (10BASE-T/100BASE-TX) interface achieves high-speed data transfer.

-Maintenance wavelength which has no influence to live communications

  OTDR with the maintenance wavelength (1650 nm) enables the monitoring of live communications line.
  A built-in cut filter reduces an impact of communications signals on the measurement.

-Available for test through high-port-count splitters

  Supports the measurement of the PON system including high-port-count splitters.

AQ7277B New

-Small-sized module

  The volume is reduced by 60% compared to the existing model (AQ7277).
  The mountability in the RFTS is improved.

-Wavelength lineup

  In addition to the model of the maintenance wavelength (1650 nm), there is a model of 1550 nm (DR 50 dB) which supports long distance measurement.
