摘要： A translation circuit for mediating between a fiber-optic controller chip and a host device. The translation circuit may be on a fiber-optic transponder. The controller chip includes a phase locked loop that outputs a short synchronization signal when a hunting frequency passes through a target data signal frequency while hunting for a data signal and outputs a synchronization signal when the phase locked loop is locked onto a data signal. The translation circuit distinguishes between the synchronization signals and generates a lock signal when the phase locked loop is locked onto a data signal, but does not when the hunting frequency passes through the target data signal frequency. The lock signal may be used by a host device into which the fiber-optic transponder has been in installed. Errors from misinterpreted signals can thus be mitigated.

摘要： A general method is given for screening laser diodes for electrostatic discharge, (ESD), damage. The laser diode may be selectively isolated from the laser driver so that a current-voltage (I-V), curve can be taken and then compared to curves taken previously on the same laser diode to ascertain the possibility of ESD damage. Presumably the initial I-V curve will be representative of the characteristics of that particular laser in the undamaged state. Such an initial curve may be supplied by the manufacturer and may be a curve specific to a particular laser diode. Comparison with a standard curve is not sufficient to determine ESD damage in the early stages of failure. Some embodiments focus on isolating the laser diode from the laser driver, storing the information locally in the transceiver, and providing some analysis resulting in flagging laser diodes showing changes that are indicative of ESD damage.

摘要： Optical transceivers have loopback and pass-through paths for diagnosing transceiver components and optical networks connected to the optical transceiver or for routing data out of the transceiver in a pass-through mode. The loopback paths are selectively configured so that a selected number of the components in the transceiver are included in the loopback path. Where more than one loopback path is present, a network administrator can select which components will be included in a particular test so that, depending on whether a signal is returned on the loopback path as intended, the network administrator can determine which components are operating correctly and which are faulty. The loopbacks can be configured to run on the electrical side of the transceiver from input port to output port or on the optical side from receiver to transmitter. The pass-through paths can be used to connect the transceiver to other devices.

摘要： A dual stage optical modulator is disclosed that uses optical predistortion to achieve a high degree of linearity and also provides signals having substantially no residual phase modulation, or chirp. The modulator allows fiber optic transmission over fibers having a zero dispersion wavelength that is significantly different from the operating wavelength of the source laser without a chirp-induced dispersion penalty. In one embodiment of the modulator, an input Y-junction splits an optical input signal into a first interferometer, also referred to as a phase/intensity modulator, having first and second interferometer arms and an electrode structure for modulating the split signal. The electrode structure includes a pair of ground electrodes and a modulating electrode for receiving a first RF modulating voltage and associated DC bias. The modulating electrode is positioned between the interferometer arms but is offset from the center of the arms for providing a first asymmetric electro-optic effect through the introduction of intensity modulation and residual phase shift in the split signals. The split signals are then mixed in unequal proportions in a directional coupler and are separated into a second phase/intensity modulator that is substantially similar to the first, but which receives a second RF modulating voltage. The signals from the second phase/intensity modulator are again mixed in unequal proportions in a second directional coupler which couples the signals and provides first and second optical output signals. Linearization is achieved through optical predistortion by adjusting the DC biases and attenuating the second modulating voltage with respect to the first such that any distortion generated in the first interferometer is canceled in the second interferometer. Chirp introduced in the signals by the first interferometer is reduced in the second interferometer and directional couplers and is eliminated in at least one of the output signals by appropriately selecting the amount of asymmetric phase distortion applied to the signal in each stage.
