    摘要： A GPON module comprises a housing and a circuit board disposed in the housing. The circuit board further includes ground lines that substantially isolate regions of the circuit board, an electro-optical interface for converting an inbound optical signal to an electrical signal and processing circuitry that is arranged to provide an electrical RF signal to an RF interface. The RF interface comprises a three-pin RF connector exposed from the housing, wherein the RF connector is coupled directly to the circuit board, and two of the three pins are coupled to ground.

    摘要： A coherent light source having a semiconductor laser resonator and an optical amplifier which amplifies coherent light emitted by the semiconductor laser resonator in response to current injection, in which the amount of current injected into the semiconductor laser is controlled for conformity with a chirp requirement of an optical communication system. The optical amplifier, which introduces no chirp, may be controlled to match an optical power requirement of the optical communication system. A heater may be provided to introduce a low frequency chirp in order to suppress interferometric intensity noise and unwanted second-order effects such as stimulated Brillouin Scattering. The optical amplifier may be monolithically formed with the semiconductor laser resonator, with separate electrodes provided for injecting current into the semiconductor laser resonator and the optical amplifier.

    摘要： An improved local synchronization module which uses Frequency-phase adaptive double locked loop (FPADLL) to control a stable controllable oscillator is disclosed. A single physical feedback loop is implemented which can operate in either a phase locked loop mode or a frequency locked loop mode. The sync module includes a controller which determines in which mode the feedback loop operates. The controller also uses slipping information from a network reference recovery interface to reduce slipping. Also effects of ageing of the stable controllable oscillator are predicted and compensated for.

    摘要： A passive optical network transceiver including a surge protection circuit so as to protect the electro-optical circuitry from lightning or other electrical surges. The surge protection circuit includes a ground line and at least one capacitor provided in a first line. In particular, the capacitance value of the capacitor is such as to limit the surge current in the first line, and the breakdown voltage of the capacitor is such as to limit the surge voltage between the first line and the ground line. In one embodiment, the surge protection circuit includes a second line connecting the first line to the ground line and at least one inductor provided in the second line. The surge protection circuit may include one capacitor with small value and high voltage rating, and multiple capacitors with larger value and lower voltage rating.
