It provides 2×2 non-blocking matrix switching with bi-directional signal paths, enabling flexible optical signal routing for transceiver and receiver testing, as well as multi-passive component characterization.

– Technical Specifications

• Configuration: 2×2 non-blocking matrix with bi-directional signal paths
• Switching Time: Typically < 10 ms, 10 ms, or 15 ms
• Insertion Loss: < 1.5 dB
• Polarization Dependent Loss (PDL): 10 million cycles
• Maximum Input Power: 300 mW
• Operating Temperature: 10 °C to 45 °C
• Humidity: 95% non-condensing
• Warm-up Time: 30 minutes
• Dimensions: 75 mm (H) × 32 mm (W) × 335 mm (D)
• Weight: 0.5 kg

– Key Features

• Available in single-mode (FC/APC narrow keying or SC/APC) and multi-mode (FC/PC) configurations
• Analog voltage output (0–2 V) proportional to optical signal strength; 2 V equals full power within current range
• Front-panel toggle button control or mainframe user interface operation
• Autoranging must be disabled when using analog output

– Typical Applications

Optical network laboratories, research facilities, and telecommunications environments requiring automated transceiver and receiver testing, multi-passive component analysis, and optical signal routing.
