摘要： Simplified laser drivers for closed path digital optical cables and digital optical cables including the simplified laser drivers. The laser driver can include less transistors than conventional laser drivers for optical communication cables. The laser can include a bias source and modulation source. The bias source can have a single constant current bias point for all laser diodes. The modulation current source can have a single temperature coefficient for all laser diodes. The laser driver can exclude, for example, any one of or combination of temperature compensation of the modulation or bias current sources, external programming of the modulation or bias current sources, power control based on output of the laser diode, and/or control based on feedback received from a monitor device or other sensor within the cables.

摘要： A photodiode and a method of fabricating a photodiode for reducing modal dispersion and increasing travel distance. The central region of the photodiode is made less responsive to incident light than a peripheral region of the photodiode. The less responsive central region discriminates the lower order modes such that only the higher order modes are incident on the more responsive peripheral region. Because the lower order modes are subtracted, the range of propagation constants is reduced and modal dispersion is also reduced.

摘要： Methods and apparatus for alignment of TO cans with photodiodes on fiber-optic receptacles. The methods and apparatus make use of direct connections to photodiodes or connections to Received Signal Strength Indicator (RSSI) outputs to align TO cans in fiber-optic receptacles. An optical source, such as a laser diode, can be powered by a low-frequency or DC source. This optical source can direct light into the fiber-optic receptacle. The TO can is manipulated in a barrel of the fiber-optic receptacle. The current through the photodiode or the RSSI output is monitored to determine when light directed into the photodiode is at a maximum or above a predetermined threshold. The TO can is fixed in the barrel when the light directed into the photodiode is at the maximum or predetermined threshold.
