A USB connector is provided that has an OE module and high-speed electrical connections integrated therein. The OE module includes an optical module, at least one laser diode, at least one photodiode, an optical transceiver IC, and a PCB. The optical module, the laser diode, the photodiode, and the IC are mounted on a surface of the PCB. The OE module is secured within the USB connector. The PCB includes conductive traces and electrical contact pads. The conductive traces electrically connect the IC with the contact pads. The contact pads are electrically connected via through holes formed in the PCB to the high-speed electrical connections, which, in turn, are electrically connected to conductive traces of a motherboard or a computer.

Embodiments introduce redundant optical channels to significantly extend the lifetime of parallel optical transceivers. A plurality of transmitters, N, transmit on a plurality of optical channels, where N is an integer number of optical channels greater than 1. One or more redundant channels, M, are also provided. N+M multiple input shift registers provide multiple paths for signals from each of the transmitters to connect to N+M laser diodes. In the event up to M of the N+M laser diodes fail, the multiple input shift registers connect the N transmitters to functioning ones of the N+M laser diodes thus extending the life of the device. A corresponding scheme is also described for the receiver side.

A laser driver for generating drive waveforms that are suitable for driving a single VCSEL or an array of VCSELs. A digital controller is integrated into the laser driver and is utilized to initially program and selectively adjust during the operation of the driver one or more of the following VCSEL drive waveform parameters: (1) bias current, (2) modulation current, (3) negative peaking depth, and (4) negative peaking duration.

The laser driver also has a temperature compensation mechanism for monitoring the temperature of the driver IC and selectively adjusting the dc and ac parameters of the VCSEL drive waveform to compensate for the changes in temperature.
