3. What is EPON
 Ethernet passive optical networks (EPON) are an
emerging access network technology that provides
a low cost method of deploying optical access lines
low-cost
between a carrier office (CO) and customer site.
 We can say that, Ethernet Passive Optical Networks
(
(EPONs) represents the convergence of low-cost
) p g
Ethernet equipment and low-cost fiber
infrastructure, to be the best candidate for the Next-
Generation access network.

8. Benefits - P2MP
 Lower cost
 Fewer optic
modules
 Less fiber
Point-to-multi points, need of
(N+1) receive modules, the fiber
amount is(D1+N*D2)
