    Photline Technologies offers modulator bias controller with continuous tuning

    Oct. 10, 2007
    OCTOBER 10, 2007 -- The new MBC-1001 is a modulator bias controller designed to stabilize the operating point of LiNb03 Mach-Zehnder modulators.

    OCTOBER 10, 2007 -- Photline Technologies' (search for Photline) new MBC-1001 is a modulator bias controller designed to stabilize the operating point of LiNb03 Mach-Zehnder modulators. The MBC-1001 features continuous tuning of the operating point over the transfer function of the modulator, whereas classical systems only offer a limited choice of points (typically : Min, Max, Quad+, Quad-).

    This new capability is especially useful to accommodate the large variety of modulation formats used in new generation telecom systems, Photline says. It allows also enables compensation for the slight bias shift often caused by the modulators' internal monitoring photodiodes.

    The MBC-1001 is a bench-top instrument with a front-panel manual interface and LabView GUI through an RS-232 interface. The company says the system is compatible with all Mach-Zehnder type modulators and can operate with the photocurrent provided by an internal monitoring photodiode or by an external tap photodiode.
