Optical fiber interconnection devices and systems using same

摘要

Optical fiber interconnection devices, which can take the form of a module, are disclosed that include an array of optical fibers and multi-fiber optical-fiber connectors, for example, a twenty-four-port connector or multiples thereof, and three eight-port connectors or multiples thereof. The array of optical fibers is color-coded and is configured to optically interconnect the ports of the twenty- four-port connector to the three eight-port connectors in a manner that preserves transmit and receive polarization. In one embodiment, the interconnection devices provide optical interconnections between twenty-four-fiber optical connector configurations to eight-fiber optical connector configurations, such as from twenty-four-fiber line cards to eight-fiber line cards, without having to make structural changes to cabling infrastructure. In one aspect, the optical fiber interconnection devices provide a migration path from duplex optics to parallel optics.
