YOKOGAWA AQ7277B Remote OTDR Optical Time Domain Reflectometer

FEATURES High performance OTDR module for RFTS (Remote Fiber Test System) The AQ7277B is 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 -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.
