An optical power meter unit includes a transmitting/receiving port configured to connect to a fiber under test. The optical power meter unit also includes a light source and an optical power meter. The optical power meter unit further includes an optical fiber extending between the transmitting/receiving port and the optical power meter. The optical fiber has a core size greater than a core size of the fiber under test.

A method of identifying and testing an optical fiber includes emitting light into the optical fiber. The light includes an identification signal and a testing signal. The method also includes reading the identification signal and the testing signal with a single device. The method further includes determining an identity of the optical fiber based on the identification signal with the single device and determining a status of the optical fiber based on the testing signal with the single device.

Systems and methods for identification and testing of optical fibers

Optical fiber adapters and connectors are provided. An optical fiber adapter includes an adapter body, the adapter body extending along a longitudinal axis between a first end and a second end and comprising a first adapter portion which includes the first end and a second adapter portion which includes the second end. Each of the first adapter portion and the second adapter portion is one of a male adapter portion or a female adapter portion. The optical fiber adapter further includes a ferrule disposed within the adapter body, the ferrule extending along the longitudinal axis between a first end and a second end, and a thin-film filter provided on one of the first end or the second end of the ferrule, wherein the thin-film filter limits the wavelengths of light transmitted therethrough to within a predetermined wavelength range.

An apparatus for measuring optical power includes a first component configured to at least one of multiplex or demultiplex between a first composite optical waveguide and at least a first intermediate optical waveguide and a second intermediate optical waveguide. The apparatus further includes a second component configured to at least one of multiplex or demultiplex between a second composite optical waveguide and at least the first intermediate optical waveguide and the second intermediate optical waveguide. The first and second components have complimentary isolation levels. The apparatus further includes a first optical coupler positioned along the first intermediate optical waveguide and a second optical coupler positioned along the second intermediate optical waveguide. The apparatus further includes a first photodetector, a second photodetector, a first measurement device, and a second measurement device.

A fiber optic interface includes a first fiber optic connector and a second fiber optic connector. The first fiber optic connector has a ferrule extending from a distal end to a proximal end. The ferrule includes a contact interface defined at the proximal end of the ferrule. A first optical fiber extends within the ferrule and terminates at a first fiber end. The first fiber end is spaced apart from the contact interface towards the distal end of the ferrule by a distance of at least five microns. The second fiber optic connector includes a second optical fiber extending within the second fiber optic connector and terminating at a second fiber end. The ferrule of the first fiber optic connector includes an end face which faces the second fiber optic connector when mated and consists of a single face.

A method for calibrating an OLTS includes calibrating a first optical power meter of the OLTS using a stabilized light source. The method further includes calibrating a second optical power meter of the OLTS using the stabilized light source. The method further includes setting a power of an internal light source using the calibrated first optical power meter. A calibration cable is connected to a first test port and a second test port during setting of the power level, and a connection of the calibration cord to the second test port is maintained between calibrating of the second optical power meter and setting of the power level.

Methods for calibrating OLTS and determining optical loss

An optical fiber test apparatus includes an optical power meter operable to detect light at a predetermined wavelength, and a laser source operable to generate a visible laser beam. The optical fiber test apparatus further includes an optical fiber extending between a first end and a second end, and a diplexer which includes a first optical connector and is coupled to the optical power meter, the laser source, and the first end of the optical fiber. The optical fiber test apparatus further includes a second optical connector coupled to the second end of the optical fiber and including a test port. The diplexer is operable to transmit light at the predetermined wavelength from the second optical connector to the optical power meter and transmit the visible laser beam from the laser source to the second optical connector.
