ROF -ABC automatic bias point controller
Product description
ROF-ABC automatic bias point controller can be used to control the bias point of a M-Z intensity modulator, or six bias points of two QPSK modulators, which is suitable for such fields as optical fiber sensing, and PM-QPSK modulation in optical fiber communication. The automatic bias controller can be integrated with other circuits that are use for lithium niobate modulator, or used as a separate module. The power adapter can provide power when the controller is used as a separate control module.
Features |
l Optional working mode: automatic calibration mode and memory lock mode
l Multiple bias points are available (Quad+↔Quad-，Min ↔Max)
l Additional program-controlled auto-tuning back to lock the offset point
l Operating wavelength range ：1000nm—1650nm
l Ultra min size （77.30mm×40.40mm），easy to integrate
l Multiple module can be choose for different modulator
Applications |
l LiNbO3 modulator
l Optical fiber communication
l Analog application
l Pulse light application
