Passive Optical LAN (POL) is to the traditional Ethernet LAN what fiber-to-the-home is to traditional copper telephone lines. POL brings the power of fiber optic broadband technology to enterprises, university campuses, hospitals, hotels or anywhere else that needs a Local Area Network.
POL uses fiber-optic cable instead of copper and the Gigabit Passive Optical Network (GPON) transmission technology to transmit Ethernet frames. GPON is used to deliver commercial and mission-critical broadband services to millions of users worldwide.
However, Ethernet LAN does have one thing going for it: familiarity. Ethernet LAN is a 30-year old technology. It is tried and trusted and, by and large, does the job it’s meant to do.
But bandwidth needs in the office are growing as rapidly as at home. Perhaps more so. Ethernet LANs are reaching their capacity limitations and many enterprises are considering how their LANs will cope 5, 10, 20 years from now. Many are also looking to their IT managers to deliver cost savings from their local area networks and services.
