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:

•Simultaneously provides six automatic bias voltages for Dual Polarization IQ modulators
•Modulation format independent:
SSB, QPSK, QAM, OFDM 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) × 29mm(D) ×8mm(H)
•High stability: fully digital implementation Easy to use:
•Manual operation with mini jumper 2
Flexible OEM operations through UART /IO
•Two modes to provide bias voltages: a.Automatic Bias Control b.User defined bias voltage

Application:

•LiNbO3 and other DP-IQ modulators
•Coherent Transmission

¹ The highest extinction ratio depends on and cannot exceed 1 the system modulator maximum extinction ratio.

² UART operation is only avaliable on some version of the controller.

1 MER refers to intrinsic Modulator Extinction Ratio. The extinction ratio achieved is typically the extinction ratio of the modulator specified in modulator datasheet.
² Let Vπ denote the bias voltage at 180° and VP denote the most optimized bias voltage at Quad points.
³ Please be noted that the input optical power does not refer to the optical power at the selected bias point. It is the maximum optical power that the modulator can export to the controller when the bias voltage ranges from −Vπ to +Vπ .
