JDS Uniphase MAP-VOA

The JDS Uniphase MAP-VOA is a modular variable optical attenuator engineered for integration into the JDS Uniphase MAP Series platform. This hot-swappable cassette module delivers precise optical power control across the C- and L-bands, supporting both single-mode and multimode fiber configurations. Operating wavelengths span 1260 nm to 1650 nm, with attenuation capability up to 70 dB and guaranteed accuracy of ±0.1 dB from 0 to 45 dB. The 0.001 dB setting resolution enables fine-grained signal conditioning in automated test environments, laboratory setups, and production line applications. Insertion loss remains below 1.0 dB at minimum attenuation, while repeatability of ±0.01 dB ensures consistent measurement results across multiple cycles. With maximum input power handling of +23 dBm (up to 2 W for single-mode fiber with optional higher power capability), the MAP-VOA accommodates high-power optical signals. Return loss exceeds 55 dB typical, and shutter isolation reaches 100 dB typical. Remote control via RS-232 and GPIB interfaces enables seamless integration into automated test sequences. Up to 16 independently controlled attenuators can be installed in a single MAP chassis. The modular architecture allows insertion and removal without system power-down, supporting rapid system reconfiguration and maintenance.
