Abstract: An optical cable includes an optical component assembly, inner and outer optical fibers, a componentry cover, and a connector. The optical component assembly includes an optical unit. The inner and the outer optical fibers are on opposing sides of the optical unit such that the optical unit receives a first optical signal from the inner optical fiber and the outer optical fiber receives a second optical signal from the optical unit or such that the optical unit receives the second optical signal from the outer optical fiber and the inner optical fiber receives the first optical signal from the optical unit. The componentry cover encapsulates an entirety of the optical unit and portions of the inner and the outer optical fibers. The connector includes a portion of first outer optical fiber that is exposed to route the second optical signal.

Abstract: The present disclosure is directed to an optical device including at least one temperature-dependent tunable element for controlling a wavelength of an optical signal, a first temperature control circuit for controlling a temperature of a first region of the optical device; and a second temperature control circuit for controlling a temperature of a second region of the optical device. The second region may include a portion of the first region. The second region may be smaller than the first region. The tunable element may be positioned in the second region such that a temperature of the tunable element is controlled based on the second temperature control circuit controlling the temperature of the second region. The tunable element may be one of (i) a laser for transmitting an outgoing optical signal and (ii) an optical filter coupled to a photodetector for receiving an incoming optical signal.

Abstract: A connector assembly includes an adapter, a housing device, a ferrule assembly, and a sensor. The housing device is received by the adapter and has a bore, a front end, and a rear end opposite the front end. A ferrule of the ferrule assembly is within the bore of the housing device and has a mating end extending beyond the front end of the housing device. The sensor is mounted on the rear end of the housing, the rear end of the ferrule assembly, or on the adapter confronting and spaced apart from the housing device or the ferrule assembly. The sensor is configured for detecting a force applied by the housing device or the ferrule assembly, respectively. An electrical characteristic of the sensor changes to indicate a predetermined force has been applied by the housing device or the ferrule assembly, respectively.

Abstract: The present disclosure is directed to an optical device including at least one temperature-dependent tunable element for controlling a wavelength of an optical signal, a first sensor configured to indirectly monitor the optical signal, a second sensor configured to directly monitor the optical signal, and a control circuit. The tunable element may be one of (i) a laser for transmitting an outgoing optical signal and (ii) an optical filter coupled to a photodetector for receiving an incoming optical signal. The control circuit may be configured to receive first and second inputs from the first and second sensors, respectively, adjust the tuned wavelength of the tunable element from a first preselected wavelength to a second preselected wavelength based on the first input received from the first sensor, and maintain the tunable element at the second preselected frequency based on the second input received from the second sensor.

Abstract: An optical signal routing device may include a first lens, second lens and a wavelength division multiplexer (“WDM”) filter positioned between the first and second lenses. The WDM filter may reflect a signal of a first wavelength with a first attenuation and pass the first wavelength signal attenuated by at most a second attenuation to the second lens, the first attenuation exceeding the second attenuation by a first predetermined amount. The WDM filter may reflect a signal of a second wavelength different than the first wavelength with at most a third attenuation, the first attenuation exceeding the third attenuation by at least a second predetermined amount. The device may further include a reflector positioned to reflect the first wavelength signal reflected by the WDM filter toward the WDM filter with at least a fourth attenuation, the fourth attenuation exceeding the second attenuation by at least a third predetermined amount.

Abstract: A cable guide apparatus includes a first longitudinal channel defined by first, second, and third walls, the third wall toward and away from the first. The second and third walls may have a plurality of openings to facilitate bending of the longitudinal channel and any cables secured therein. The first wall may include a plurality of closure mechanisms, such as hooks, and the third wall may include a plurality of closure mechanisms, such as lips. The cable guide apparatus has an open condition in which cables may easily be inserted into the channel, and a closed condition in which the cables are secured in the channel. The width of the openings may define a maximum amount the cable guide apparatus may bend, such that cables secured within the apparatus do not bend to the point of being damaged.

Abstract: An optical device has a first frame element and second frame element. At least portions of a plurality of optical fiber pairs of an array each including an exposed end are arranged between the two frame elements. A region is defined between opposing surfaces of the two frame elements to hold the optical fibers. When holding the fibers, the two frame elements cooperate to positionally align and orient the exposed ends of each of the optical fibers for at least one of transmitting and receiving light. An optical system with the device includes a TAP photodiode array such that a portion of light is transmitted from at least a pair of input optical fibers to a corresponding pair of photodiodes of the array, and a portion of light is reflected back from an optical filter to output optical fibers corresponding to the input optical fibers.
