            Optical LAN Service 
            Options
		
		
			
            Optical LANs are characterized by 
            high-quality links, low latency, and the freedom to choose the 
            topology. This permits extremely high-quality transparent circuits 
            which might be used for analog signal distribution or Internet 
            access. 
            Store-and-forward 
            optical packet/cell switching architectures are also possible, but 
            suffer from the same limitations discussed under MANs.
