摘要： A DC level detection circuit between high speed signal line connecting ports and a system using the same in optical communications is disclosed. Corresponding ports of a high speed signal line each have an additional resistor, where one additional resistor has a resistance significantly greater than that of the other resistor. The smaller resistor is grounded. The larger resistor is connected to a DC voltage source, a low pass filter, and a signal detection port. Thus, when both ports of the high speed signal line are connected, a status of the electrical level detected at the signal detection port changes. The circuit detects the connection state of the high speed signal line without negative effects on signal transmission and is applicable to various circuits, especially plug-in modules and corresponding slots. Thus, the circuit further enables signal port multifunctionality, increases module installation accuracy, and provides higher compatibility for plug-in modules.

摘要： The present invention relates to an optical module and optical module system using the same. The optical module comprises a transceiving unit, an antenna and an MCU. The transceiving unit receives control commands from one or more control computers via the antenna and transfers them to the MCU. Then the MCU processes the control commands and provides feedback information to the one or more control computers through the transceiving unit. In the optical module of the present invention, as a result of an additional IOT wireless unit, the optical module is capable of communicating with remote control computers, thereby achieving remote testing and control for optical modules, instead of using conventional control methods for optical modules.

摘要： A dual-rate power point compensating circuit, comprising a microprocessor and a transmitter optical subsystem assembly (TOSA), wherein the TOSA includes a laser connected to a laser driver, a monitor photodiode (MPD) connected to the laser driver, and a current divider connected to the microprocessor and the MPD. When a feedback current from the MPD exceeds the adjustable and/or operating range of the laser driver, the feedback current is reduced so that it is kept in the adjustable and/or operating range of the laser driver. The laser driver determines the optical output power of the laser from the value of the reduced feedback current. The circuit and method extend the adjustable and/or operating range of a laser driver and enable it to regulate a target optical output power of the laser with a broad testing range and high accuracy when the feedback current is relatively high.

摘要： A gain-variable trans-impedance amplifier (TIA) in optical device is disclosed. The TIA has an improved dynamic range for receiving electrical signals and is configured to convert current signals from an avalanche photodiode (APD) to voltage signals. A resistor element is between the input and output terminals of the TIA, wherein the resistance of the resistor element can regulate the resistance and/or impedance value of the TIA, and a switch determines or controls the resistance of the resistor element. When the power of an optical signal received by the APD is higher than a predetermined value, the resistance becomes smaller and the gain of the TIA becomes greater. When the power of the optical signal is lower than the predetermined value, the resistance becomes greater. The gain of the TIA is automatically adjusted on the basis of the intensity of received optical signals to obtain a greater dynamic operational range.

摘要： A small form-factor pluggable (SFP) optical transceiver includes a casing configured to accommodate optical and electrical devices. During normal operation, the casing is connected to a switchboard via a connector in the switchboard, and the optical devices are outside the switchboard, thereby exposing optical devices sensitive to high temperature to the outside air, reducing the operational temperature of the optical device portion relative to the heated portion inside the switchboard. Thus, the present SFP optical transceiver advantageously improves operational performance and extends the life of the device. Also, the present SFP optical transceiver having the optical device portion outside the switchboard advantageously improves the cooling performance for the optical device portion.
