Abstract
An active optical network switch having a switch module, a plurality of uplink modules and a plurality of downlink modules connected to a backplane for connecting the modules and passing signals among them. A CPU module assists in managing the routing of traffic signals by the switch module; said modules and backplane are enclosed in an environmentally hardened housing. Six downlink modules may include four downlink ports each, for connecting the switch to twenty-four subscribers. Multiple switches may be daisy-chained together; one being a master and the remainder being slaves, to increase the number of subscribers that are served by an uplink fiber/pair. Dense Wavelength Division Multiplexing may aggregate traffic signals between many subscribers and a CO/head end along a single backhaul fiber. Switch software may provide 'network edge' functions including traffic shaping, policing, filtering and aggregation, and address control.
