Description by Manufacturer

Rofea' modulator bias controller is specially designed for Mach- Zehnder modulators to ensure a stable operation state in various operating environments. Based on its fully digitized signal processing method, the controller can provide ultra stable performance.

The controller injects a low frequency, low amplitude dither signal together with bias voltage into the modulator. It keeps reading the output from the modulator and determines the condition of the bias voltage and the related error. A new bias voltage will be applied afterwords according to the previous measurement. In this way, the modulator is ensured to work under proper bias voltage.

Feature:

•Provides three biases for IQ modulators Modulation format independent:
•QPSK, QAM, OFDM, SSB verified
•Plug and Play:
No manual calibration needed Everything automatic
•I, Q arms: controll on Peak and Null modes High extinction ratio: 50dB max1
•P arm: controll on Q+ and Q- modes Accuracy: ± 2°
•Low profile: 40mm(W) × 28mm(D) × 8mm(H)
•High stability: fully digital implementation Easy to use:
•Manual operation with mini jumper Flexible OEM operations through UART2
•Two modes to provide bias voltages: a.Automatic Bias Control b.User defined bias voltage

Application:

•LiNbO3 and other IQmodulators
•QPSK, QAM, OFDM, SSB and etc
•Coherent Transmission

1. MER refers to Modulator Extinction Ratio. The extinction ratio achieved is typically the extinction ratio of modulator specified in modulator datasheet.
2. Please be noted that input optical power does not correspond to the optical power at selected bias point. It refers to the maximum optical power that the modulator can export to controller when bias voltage ranges from −Vπ to +Vπ .
