    • A programmable digital black level calibration circuit comprises a combining circuit, a digital programmable gain amplifier (PGA), and a black level feedback circuit. The combining circuit combines a digital image signal for optical black (OB) pixels and a feedback signal and outputs a digital PGA input signal. The PGA amplifies the digital PGA input signal by a PGA gain value and outputs a digital PGA output signal. The black level feedback circuit receives the digital PGA output signal and a target black level and in response outputs the feedback signal such that a black level of the OB pixels is calibrated with respect to the target black level. The programmable digital black level calibration circuit calibrates the black level in pure digital domain using signed data buses. The target black level is adjustable to a desired positive or negative value independent from the PGA gain value.

    • An optical module which can be inserted into and removed from a cage, the optical module includes a lock pin inserted into a lock hole provided in the cage and engaging the cage and the optical module with each other in a state where the optical module is inserted into the cage; a tongue having an axial part and configured to be rotated with respect to the axial part in a direction where the insertion of the lock pin into the lock hole is released; and a bail configured to be rotated with respect to a rotational axel so that the tongue is rotated. The engagement of the cage and the optical module formed by insertion of the lock pin into the lock hole is released by rotating the bail 90 degrees.

    • A case containing an optical interface section including a connector-fitting unit in its front portion, a printed board in its central portion, and an electrical interface section in its rear portion is accommodated in a housing. When a data link module is inserted in a cage, a housing tongue and a through hole both formed in a bottom plate of the housing are overlapped with a cage tongue and a lock pin both provided in and on a bottom plate of the cage, into and from which the data link module is inserted and removed, such that the lock pin is engaged in and locked by the lock hole. When removing the data link module from the cage, by angularly turning a bail pivotally supported by the connector-fitting unit, the cage tongue is pushed down following to the housing tongue with the camming operation of a plate cam, thus causing the lock hole to be disengaged from the lock pin.

    • An optical fiber amplifier employs an optical fiber and an optical coupler. The optical fiber has a core and a clad. The core has an erbium-aluminum-doped center and an erbium-doped annular section. The optical coupler guides signal light and pump light to the optical fiber, which amplifies the signal light using the pump light. The center of the core corresponds to a section where the field diameter of the signal light overlaps that of the pump light. The annular section is outside the field diameter of the pump light. The amplifier provides a required gain without employing optical parts such as filters. The signal light has a wavelength in the 1.5-micrometer band, and the pump light has a wavelength, in the 1.45-micrometer band, corresponding to the absorption band of erbium. The present invention may further employ pump light having a wavelength in the 0.98-micrometer band. The optical fiber may be doped with erbium and aluminum only in an annular section around the center of the core, to prevent a gain drop near a wave length of 0.98 micrometers.
    • 光纤放大器采用光纤和光耦合器。 光纤具有芯和包层。 芯具有铒铝掺杂中心和掺铒环形部分。 光耦合器将信号灯和泵浦光引导到光纤,光纤使用泵浦光放大信号光。 芯的中心对应于信号光的场直径与泵浦光的直径重叠的部分。 环形部分在泵浦光的场直径之外。 放大器提供所需的增益,而不使用诸如滤波器之类的光学部件。 信号光的波长为1.5微米,泵浦光的波长为1.45微米,与铒的吸收带相对应。 本发明还可以使用波长在0.98微米波段的泵浦光。 光纤可以仅在围绕芯的中心的环形部分中掺杂铒和铝,以防止在0.98微米波长附近的增益下降。
