Optical transmission line |
摘要 |
<p>There is provided an optical transmission line that includes a bend insensitive fiber (BIF) defined by ITU-T Recommendation G.657 and that reduces the influence of MPI. An optical transmission line 1 includes a first optical fiber 11, a second optical fiber 12 joined to an incident end of the first optical fiber 11, and a third optical fiber 13 joined to an exit end of the first optical fiber 11. The first optical fiber 11 is a bend insensitive fiber (BIF), and each of the second optical fiber 12 and the third optical fiber 13 is a general single mode optical fiber. An attenuation coefficient of an LP11 mode in the first optical fiber 11 at a wavelength of 1310 nm, a splice loss between the first optical fiber and the second optical fiber, a splice loss between the first optical fiber and the third optical fiber, and a length of the first optical fiber satisfy a predetermined relational equation.</p> |
