Abstract

A fiber optic jumper assembly comprising at least one bend performance optical fiber comprising a core region and a cladding region surrounding the core region, the cladding region comprising an annular hole-containing region comprised of non-periodically disposed holes, a protective covering positioned over the at least one bend performance optical fiber, and at least one connector mounted upon each end of the at least one bend performance optical fiber. A preconnectorized fiber optic jumper assembly comprising a microstructured fiber having a delta attenuation of 0.00 dB at 5 wraps about a 6 mm diameter at a reference wavelength of 1625 nm.

Claims

1. A preconnectorized fiber optic jumper assembly comprising:

a microstructured fiber having a hole-free inner annular cladding region surrounding the core region, an annular hole-containing cladding region surrounding the inner annular cladding region and comprised of non periodically disposed holes, and an outer hole-free cladding region surrounding the annular hole-containing cladding region, wherein the core region has a radius R1 in the range from 1 μ

m to 5 μ

m, the inner annular cladding region has a radius R2 in the range between 10 μ

m and 20 μ

m, and the annular hole-containing cladding region has an annular width W23 in the range from 0.5 μ

m to 20 μ

m;

at least one connector mounted upon each end of the at least one microstructured fiber; and

wherein the microstructure fiber has a delta attenuation of 0.00 dB at 5 wraps about a 6 mm diameter at a reference wavelength of 1625 nm.

2. The preconnectorized jumper assembly of claim 1, wherein the microstructured fiber has 12 mm macrobend induced loss at 1550 nm of less than 0.1 dB/turn.

3. The preconnectorized jumper assembly of claim 1, wherein the microstructured fiber has a 12 mm macrobend induced loss at 1550 nm of less than 0.05 dB/turn.

4. The preconnectorized jumper assembly of claim 1, wherein the microstructured fiber has an 8 mm macrobend Induced loss at 1550 nm of less than 0.2 dB/turn.

5. The preconnectorized jumper assembly of claim 1, wherein the microstructured fiber has an 8 mm macrobend induced loss at 1550 nm of less than 0.1 dB/turn.
