AQ7277B Remote Optical Time Domain Reflectometer
Accurate, Remote, Reliable
The AQ7277B delivers precise, high-resolution reflection analysis for fiber-optic network monitoring and troubleshooting.
Designed for demanding applications in telecommunications operations, maintenance, and aerospace remote sensing, this remote OTDR enables Remote Fiber Test Systems (RFTS), combining robust performance with user-friendly operation.
Key Features
- Built for remote fiber monitoring
- Two wavelength options: 1650 nm for live-fiber monitoring and 1550 nm for long-distance testing
- High dynamic range: up to 50 dB typical
- Short event dead zone: 0.6 m typical
- High sampling resolution: minimum 2 cm
- Remote control interfaces: LAN and USB
- Alarm output function for system integration and status monitoring
Ready-to-Run with AQ7933 OTDR Emulation Software
Pre-integrated compatibility with AQ7933 enables rapid deployment and seamless integration into remote fiber test systems.
Designed for Monitoring Live and Long-Haul Fiber Networks
The AQ7277B-B01 uses 1650 ± 5 nm, which is suited to maintenance and monitoring of live fiber lines. The AQ7277B-B02 uses 1550 ± 25 nm and offers 50 dB typical dynamic range, making it suitable for testing long-distance fiber links.
Compact Module for Easy System Integration
The AQ7277B is designed as a compact form factor for embedding into remote test systems. Its dimensions are 230 mm (W) × 50 mm (H) × 140 mm (D) and its weight is approximately 1 kg. Compared to the previous model, its size is reduced by 60%, improving integration into RFTS platforms.
Reliable Remote Operation
For remote operation and system control, the AQ7277B supports 10BASE-T/100BASE-TX Ethernet and USB 2.0, with status query and LED drive signal alarm outputs available for external system linkage.
