Abstract
A multi-core optical fiber has dimensions to be backwards compatible with a conventional, single-core optical fiber of the single-mode or multimode type. In one embodiment, the center core has a diameter, such as 3 to 9 um, 50 um or 62.5 um. Such a multi-core optical fiber can be used in connector envelopes like an LC, SC, ST or an array connector, such as an MTP/MPO connector, and will permit the fiber optic connector to continue supporting conventional transmission using only the central core of the optical fiber. Yet, allow fiber optic networks to be upgraded from supporting conventional transmission to parallel transmission using the multiple cores within the optical fiber at a later date.
