Transformation of the Enterprise Network Using Passive Optical LAN

The rapid growth of bandwidth requirements and the changing role of enterprise networking are causing disruptive change in the enterprise Local Area Network (LAN). Incumbent vendors are recommending upgrading Ethernet switches to 10 Giga-bit Ethernet (GbE) uplinks which typically require single-mode rather than multimode fiber optic cable and replacement of lateral CAT 5 cable with CAT 6 cable. Enterprises facing such disruptive change to either an existing enterprise site or a new enterprise site have the opportunity to dramatically reduce Total Cost of Ownership (TCO) by moving to a Passive Optical LAN (POL) solution, rather than continuing with the Present Mode of Operations (PMO) which uses a two- or three-tier switched Ethernet solution.
