METHOD AND DEVICE FOR FIBER ACCESS PHYSICAL LAYER UNBUNDLING USING MULTIPLE UPLINK CARDS

摘要

A system, an unbundling optical line terminal (OLT)(302, 602), and a method are described herein that allow at least two service providers (SPs)(304-1...304-N, 604-1...604-N) to use individual fibers of an optical distribution network (ODN)(307, 607). In one embodiment, the unbundling OLT (30) includes one or more wavelength division multiplexing-passive optical network (WDM-PON) line cards (308-1...308-M) and one or more SP uplink cards (312-1..312-L) that enable multiple SPs (304-1...304-N) to each utilize one uplink port (334-1) to access individual wavelengths of one or more passive optical networks (PONs)(306-1...306-M). In another embodiment, the unbundling OLT (602) includes one or more point-to-point line (p2p) line cards (608-1...608-M) (e.g., p2p fiber Ethernet line cards) and one or more SP uplink cards (61 2-1...612-L) that enable multiple SPs (604-1...604-=N) to each utilize one uplink port (634-1) to access one or more individual fibers (606-1...606-M).
