In an aspect there is provided a connector device. The connector device may include a cable connector having a housing having an opening at a first end and a cable gland at a second end; and a sleeve having an internal channel configured to interchangeably couple with an electrical transceiver module type and an optical transceiver module type. The internal channel may extend between a first end and a second end of the sleeve. The first end of the sleeve may be configured to insert through the opening in the housing to releasably couple the sleeve to the housing. The second end of the sleeve may be configured to insert through a port on a unit and couple the electrical transceiver to an edge connector on a printed circuit board (PCB) when the electrical transceiver is coupled with the sleeve. The second end of the sleeve may be further configured to insert through the port on the unit and couple the optical transceiver to the edge connector on the PCB when the optical transceiver is coupled with the sleeve. Related systems and methods are also described.

Small form-factor pluggable connector system

Methods and apparatus are provided to facilitate the alignment of an antenna. In one aspect, there is provided a transceiver. The transceiver may include an antenna and a downconverter module coupled to the antenna. The downconverter module may convert a signal received at the antenna to another signal. The downconverter module may measure received signal strength. The transceiver may also include a sequence detector for detecting an error rate of a sequence included in the other signal. The transceiver may also include an output module for providing an output representative the error rate, the received signal strength, and a combination of the error rate and the received signal strength. The provided output may be used to enable alignment of an antenna. Related apparatus, systems, methods, and articles are also described.

E-Band receiver and bit error measurement

A particle detection system uses a reflective optic comprising a curved surface to detect high angle scattered light generated by a particle in a liquid medium, when a laser beam is incident on the particle. When the particles transit the laser beam, light is scattered in all directions and is described by MIE scattering theory for particles about the size of the wavelength of light and larger or Rayleigh Scattering when the particles are smaller than the wavelength of light. By using the reflective optic, the scattered light can be detected over angles that are greater than normally obtainable.

Systems and methods for a multiple angle light scattering (MALS) instrument having two-dimensional detector array

Systems and methods for use with an optical communication beam are disclosed. The system allows the beam of light to operate at an adequate power level that provides a robust optical link while minimizing any safety risk to humans. The system calibrates and controls the gain for an avalanche photodiode detector (APD). A detector circuit is used to calibrate the APD. Once calibrated, the detector circuit further provides an electrical bias to the APD to process or condition the electrical signal to produce a detector output. The systems and methods disclosed herein attenuate the power level of an incoming communication beam to prevent oversaturation of an APD. The system further provides an alignment signal, which is effective over a wide dynamic range of incoming power levels.

Attenuation and calibration systems and methods for use with a laser detector in an optical communication system

A system and method for use with an optical communication beam of light is disclosed. The system allows the beam of light to operate at an adequate power level that provides a robust optical link while minimizing any safety risk to humans. Such a system includes multiple operating modes which control the power output of the beam of light. In the normal mode, the beam of light operates at a selected power level which provides a desired signal to noise ratio. Once a blocking occurs, the beam of light enters a power reduction mode to prevent harm to the blocking object. An acquisition and recovery mode is then employed to reestablish the blocked communication link.

Systems and techniques for aligning relative orientation of an optical transmitter and an optical receiver that are mounted to a common fixture in an optical transceiver.

Alignment of an optical transceiver for a free-space optical communication system

A system and method for controlling the power of a transmitter helps to ensure that the transmitted signal is within the dynamic range of the intended receiver. The transmitted signal is received by the receiver. The received signal strength is measured to determine its power level in relation to the dynamic range of the receiver. Where the signal strength is too high, the transmitter is slewed to effectively decrease its pointing accuracy, thereby causing a lower-power portion of the transmitted signal to impinge upon the receiver. Similarly, where the signal strength falls below a desired level, the transmitter is slewed back toward the center-pointing position, effectively increasing its pointing accuracy, and thereby increasing the signal strength received at the receiver.

System and method for improved pointing accuracy

An optical transceiver such as used, for example, in a wireless optical network (WON), includes multiple laser sources including a first laser source configured to transmit a first 5 output channel beam having a first optical characteristic and at least a second laser source configured to transmit a second output channel beam having a second optical characteristic; multiple detectors including a first detector configured to detect a first input channel beam having the first optical characteristic and at least a second detector configured to detect a second input channel beam having the second optical characteristic; and multiple apertures including a first aperture through which the first output channel beam and the second input channel beam pass and a second aperture through which the second output channel beam and the first input channel beam pass.
