B23K 26/00
B23K 26/362
G02B 6/38

Abstract:

Methods of reshaping ferrules used in optical fiber cables assemblies are disclosed. The reshaping methods reduce a core-to-ferrule concentricity error (E), which improves coupling efficiency and optical transmission. The methods include measuring a true center of the ferrule, wherein the true center is based on an outer surface of the ferrule; and reshaping at least a portion of the ferrule to change the true center of the ferrule, wherein the reshaping includes enlarging a portion of the ferrule. A variety of reshaping techniques are also disclosed.

International Classification:

G02B 6/38

Abstract:

Methods of forming a ferrule are disclosed where the ferrule includes an inner member and an outer member. An optical fiber is secured in an axial bore of the inner member, and then offset of a core of the optical fiber from a geometric center of the inner member is determined. The outer member is then formed over the inner member to “correct” for this offset so that the core of the optical fiber ends up closer to the geometric center of the resulting ferrule. Related ferrules and cable assemblies including the same are also disclosed.

Abstract:

Methods of reshaping ferrules () used in optical fiber cables assemblies () are disclosed. The reshaping methods reduce a core-to-ferrule concentricity error (E), which improves coupling efficiency and optical transmission. The methods include measuring a distance (δ) and angular direction (θ) from a true center () of the ferrule to the core (), wherein the true center () is based on an outer surface () of the ferrule. The methods also include reshaping at least a portion (P) of the ferrule () to define a new true center () of the ferrule () and reduce the distance (δ). A variety of reshaping techniques are also disclosed.

International Classification:

G02B 6/38
G01M 11/00

Abstract:

Systems and methods of measuring ferrule-core concentricity for an optical fiber held by a ferrule are disclosed. The method includes: generating ferrule distance data by measuring distances to a ferrule outside surface as a function of rotation angle using a distance sensor and rotating either the ferrule or the distance sensor about an axis of rotation that is off-center from the true ferrule axis; aligning the axis of rotation with the fiber core; using the ferrule distance data to determine a position of the true ferrule center relative to the optical fiber core; and measuring the concentricity as the distance between the true center of the ferrule and the optical fiber core.

Abstract:

A non-contact method of measuring an insertion loss of a DUT connector is disclosed. The DUT connector has a first ferrule with a first optical fiber and a first end face. The method utilizes a reference connector having a second ferrule with a second optical fiber and a second end face. The method includes: axially aligning the first and second ferrules so that the first and second end faces are confronting and spaced apart to define a gap with an axial gap distance d; measuring values of the insertion loss between the first and second optical fibers for different gap distances d>0; and estimating a value for the insertion loss for a gap distance of d=0 based on the measured values of the insertion loss when d>0.

International Classification:

G01M 11/00

Abstract:

A controlled-contact method of measuring an insertion loss of a compressible DUT having a first ferrule with a first optical fiber and a first end face is disclosed. The method utilizes a compressible reference connector having a second ferrule with a second optical fiber and a second end face. The method includes: axially aligning the first and second ferrules to define a gap with an axial gap distance of greater than 150 μm; moving the reference connector at a connector velocity in the range from 1 mm/s to 5 mm/s; when the gap distance is less than 150 μm, reducing the connector velocity to between 10 μm/s and 500 μm/s until contact while continuing to measure the coupled optical power; after contact, increasing the connector velocity as the reference and DUT connector axially compress. The insertion loss is determined from ongoing measurements of the coupled optical power.
