US Classification:
398210, 398208, 398135, 398136, 330 59, 330308, 250214 A, 250214 AG
Abstract:
Configurable amplifiers for optical receivers and transceivers are disclosed. In one aspect, a configurable amplifier may be coupled with an output of a current-to-voltage converter to receive a voltage. The configurable amplifier may be capable of being configured to use either a substantially linear amplifier portion or a substantially non-linear amplifier portion to amplify the voltage.

International Classification:
H04B 10/08 H04B 10/06
US Classification:
398208, 398 33, 398209
Abstract:
Described is a method and apparatus for generating a mid-level reference signal and for cancelling amplifier offset in an optical communication system without DC-balancing of optical data. The apparatus comprises an optical-to-electrical converter to receive an optical signal and to generate an electrical signal; an amplifier to receive the electrical signal and to generate an output signal based on a reference signal; a feedback mechanism to be enabled during a training phase only and to generate a control signal from the output signal; and a counter logic having a digital-to-analog converter to generate the reference signal based on the control signal.

International Classification:
H04J 14/00
US Classification:
398 45
Abstract:
An optical link power management scheme takes the best advantage of a dynamic connection environment, where ports may be connected and disconnected at any time, and where data flows may start and stop as needed by the applications using the high speed data links. Power consumption is optimized, eye safety standards are met, and robust connection detection is preserved.

International Classification:
G02B 6/12
US Classification:
385 14, 385 24, 385129
Abstract:
Briefly, in accordance with one or more embodiments, a backplane includes one or more optical links and is capable of receiving one or more circuit cards. Optical signals sent via the optical links may at least partially travel in a free space region between optical elements of the circuit cards and the optical links. Optical signals may also traverse the free space between optical links in the absence of a circuit card wherein the optical signal may travel to one or more other circuit cards on the backplane. As a result, in one or more embodiments a network between one or more of the circuit cards on the backplane may be automatically configured even in the absence of one or more circuit cards from the backplane.

International Classification:
H03F 3/45 H03F 1/34
Abstract:
Techniques and mechanisms for providing signal communication with a configurable transceiver circuit. In an embodiment, an integrated circuit comprises transceiver circuitry including an output stage and current mirror circuitry. The output stage is coupled to receive a differential signal pair and to provide at least one output signal based on the differential signal pair. In another embodiment, configuration logic is operable to select between a first mode and a second mode of the transceiver circuit. The first mode includes the current mirror circuitry being disabled from providing a current signal to the output stage, and a first circuit path being closed to provide voltage to the output stage. The second mode includes the first circuit path being open and the current mirror circuitry being enabled to provide a current signal to the output stage.

Abstract:
Embodiments of the present disclosure provide laser safety techniques and configurations. In one embodiment, an optical module includes a first die including a laser configured to transmit optical signals, a first node electrically coupled with the laser, and a second node electrically coupled with the laser, and a second die including a power supply line configured to provide power to the laser, a third node electrically coupled with the power supply line and electrically coupled with the first node to provide the power to the laser, a fourth node electrically coupled with the second node of the first die, and a switch configured to prevent the power of the power supply line from reaching the laser through the third node based on a voltage of the fourth node when a laser fault event occurs. Other embodiments may be described and/or claimed.
