Abstract: The technologies described herein are generally directed to using a loopback component to test a single fiber optic strand. For example, a method described herein can include generating a first optical beam of a first wavelength. The method can further include transmitting the first optical beam via a fiber optic fiber. Further, the method can include receiving via the fiber optic fiber, a second optical beam of a second wavelength, with the second optical beam having a characteristic of the first optical beam, and with the second optical beam being generated by a non-electrical conversion of the first light of the first wavelength to the second light of the second wavelength

Abstract: Aspects of the subject disclosure may include, for example, determining distinct timing offsets between an input port and output ports of a multiport optical device. An optical signal is injected at an input port of the device to obtain output signals at the output ports, which are injected into downstream fibers. An optical multipath return signal is received via the input port of the device, including a combination of measured events including reflections, backscatter, or both. A number of similar events expected in the number of downstream optical fibers is calculated to obtain an expected multipath signature based on configuration data. Results of the optical multipath return signal are then compared to the expected multipath signature to obtain comparison results. One of the measured events is distinguished from the others based on the first comparison results and the distinct timing offsets. Other embodiments are disclosed.

Abstract: A system may use a single fiber combining module (SFCM) that combines multiple wavelength channels of different optical technologies over a single fiber. In an example, a SFCM may include a original band (O-band) port, wherein the O-band passes signals at a first wavelength range; a XGS PON port, wherein the XGS-PON port passes signals at a second wavelength range; a dense wavelength division multiplexing (DWDM) port, wherein the DWDM port passes signals at a third wavelength range, wherein the first frequency range, the second frequency range, and the third wavelength range are different; and a common port connected with a fiber, the common port simultaneously combining signals from the O-band port, XGS-PON port, and the DWDM port.

Abstract: Aspects of the subject disclosure may include, for example, receiving a first optical signal from a first optical network via a first port of the wavelength converter, receiving a second optical signal from a second optical network via a second port of the wavelength converter, modulating the first optical signal with the second light signal to generate a third optical signal, eliminating the first light signal from the third optical signal to generate a fourth optical signal, and transmitting the fourth optical signal through the second optical network. The first optical signal can include a first digital signal modulated onto a first light signal of a first wavelength, the second optical signal can include a second light signal can include a second wavelength different from the first wavelength, and the fourth optical signal can include the first digital signal modulated onto the second light signal. Other embodiments are disclosed.
