摘要： A voltage comparator (1) has a high switching speed and simplicity of design. It minimizes pulse-width distortion of input digital signals when functioning as a digital input buffer in high speed communications applications. In addition it provides a simple hysteresis circuit (31) that is easily tuneable with a reference current. The hysteresis circuit (31) is dependent on a reference current. This current may be chosen to have a proportionality to temperature, supply, or another selectable parameter, and may be programmable, in order to create the desired hysteresis performance.

摘要： An optical receiver (1) comprises a differential TIA (4) linked with a photodiode (2, 3) providing a current sense signal (I sig_tia ). The receiver is configured to provide to the TIA a sense signal as a sense TIA input (I sig_tia ) and a second input (I dark_tia ) which is a proportion of the maximum sense signal. The proportion input is half of said maximum sense signal. The inputs to the TIA are via cascode circuits (5, 6), thereby providing the advantages of a low input impedance for large area photodiodes at the TIA input, while creating a fully differential signal at the output, and the reduction of TIA bandwidth in burst mode applications, which filters out high frequency noise.

摘要： A receiver has a differential transimpedance amplifier (4) with two inputs and two outputs. The differential transimpedance amplifier (4) provides a differential output and this is peak-detected (15, 16) to provide amplitude reference signals. The differential transimpedance amplifier output and the amplitude reference signals are fed to a differential summing amplifier (10), which provides a fully differential signal to a comparator, or to an automatic gain control circuit (5) to regulate the differential transimpedance amplifier gain. The differential summing amplifier (10) output is a fully differential signal, thereby having lower distortion for DC and burst mode receiver applications.

摘要： A beam expander (100) of the invention is a single moulded transparent plastics body having a planar light input surface (101), circular in end view, upon which input light is incident, and a tapered outer reflection surface (102) forming a frusto-conical shape. A planar light output surface (103) faces in the longitudinal or axial direction and a tapered reflection inner surface (104), in a frusto-conical shape, is formed by an on-axis recess in the moulded body. All of the surfaces have an axis on a longitudinal axis of the device, namely the optical axis. Light is directed by the inner reflection surface radially towards the outer reflection surface, where it is again reflected back to axial, but with a much longer beam diameter. The overall length (t) of the beam expander is very short.

摘要： An optoelectronic device (30) has a lead frame (31) and a circuit board (34) on the lead frame. A moulded body (32) forms a lens (33) over an optoelectronic component (39). The component is placed on the lead frame (31) within an aperture (37) of the circuit board. The aperture may include a conductor on the inward-facing surface to contribute to screening of the optoelectronic component, and there may additionally be wires (51) over the aperture to contribute to screening. By virtue of being within an aperture the optoelectronic component may be physically further from the lens (33) surface, there is additional space for conductors, and there may be additional electromagnetic interference screening.

摘要： An optical receiver circuit (100) has a first photodiode (102) and a second diode (103) and an amplifier circuit (104-108) connected to the diodes. The photodiodes are arranged so that the second photodiode receives substantially the same optical signal as the first photodiode but reduced in magnitude. There is a TIA for each channel. The first photodiode is coupled to the input of a first TIA (104), and the second photodiode is connected to the input of a second TIA (105), and the receiver comprises an output (107) linked to the outputs of said TIAs. A switch (106) is connected by separate inputs to the TIAs, and a signal level detection circuit sends a control signal to the switch.

摘要： A connector (1) comprises a main body (2), and a pair of sockets (3). Each socket (3) comprises a pair of opposed resilient walls in the overall configuration of a split tube. The connector (1) also comprises a transversely sliding clamp (4) with two tapered slots (8), located so that one of the sockets (3) passes through each slot (8). After fibre terminations are pushed into the sockets (3) through the clamp (4) slots (8), the clamp is simply slid in a plane across the socket (3) axes so that the narrower ends of the slots (8) engage the opposed split tube resilient walls of each socket. This squeezes each socket so that the opposed split tube resilient walls press against the associated fibre termination and retains it in place. The sockets may have guide slots for guiding clamp movement. In most embodiments the clamp moves in a translational movement, but in another example the clamp rotates in the lateral plane to squeeze the sockets.
