Abstract: A data receiver, which could be an optical transceiver, a modem, a router hub, is capable of detecting the transmission rate of incoming data. The data is converted to electrical waves appropriate for passive or active bandpass filtering. The frequencies at which the waves are filtered are determined from a plurality of known possible transmission rates and are chosen as having the most detectable difference in the power spectra. By implementing a filter at the corresponding frequency(ies), data having that (those) frequency(ies) will be transmitted. A signal detector then can receive a signal transmitted through the filter and determine the corresponding data rate. It is further contemplated that the multiple frequencies can be filtered by using stages of filters and signal detectors for different frequencies or by filters and detectors capable of multiple frequency operation.

Abstract: An apparatus, program product and method enable a host system to read a signal or signals that are proportional to the output power and/or the bias of a laser in a fiber optic link connected to that host system without breaking that link. By reading one or more of these signals and being aware of the laser characteristics, the “health” of the laser is known and the integrity of the link is maintained. Consequently, the host system has a predictive tool which is able identify substandard lasers and replace them before a serious, and potentially costly, data disruption occurs.

Abstract: An apparatus, circuit arrangement and method enable a host system to read a signal that is proportional to the peak-to-peak optical power incident on a transceiver at one end of a fiber optic link without breaking that link. By reading this signal and being aware of the characteristics of the laser, the “health” of the laser is known and the integrity of the link is maintained. Consequently, the host system has a predictive tool that is able identify substandard lasers so that such lasers can be replaced before serious, and potentially costly, data disruptions occur.

Abstract: A flex cable has a number of conductive wirings for electrically coupling electrical leads of an electrical component to a wiring board. The flex cable has a conductive tab for electrically coupling one of the conductive wirings to one of the leads. The flex cable is bendable to form an essentially horizontal portion and an essentially vertical portion. The conductive tab is disposed at a transition between the horizontal portion and the vertical portion.
