Ethernet Over Passive Optical Networks
A well established Last - Mile technology which
affordably addresses the high bandwidth demands of
today's end users. AEM G-EPON (Gigabit-EPON) is
the architecture of choice for delivering service
performance that allows the carrier to offer high
bandwidth “Triple Play” Voice, Video and Data
services at very low access costs. An EPON uses
Point-to-Multipoint topology and eliminates active
electronic components like amplifiers,
regenerators and lasers from the outside plant. It
also saves fiber by passively coupling traffic
from up-to 256 customer-ends on-to a single fiber
that runs from a neighborhood demarcation point
back to the service provider’s CO.
-
Allow for long reach
between the CO and customer premises, operating at
distances over 20 km.
-
Minimize fiber deployment
in both the CO and the local loop.
-
Provide higher bandwidth
due to deeper fiber penetration, offering gigabit-per
second solutions.
-
Operating downstream as a
broadcast network, PONs allow for video broadcasting
either as IP video, or analog video.
-
Eliminate necessity of
installing active multiplexers at splitting
locations, relieving network operators from the gruesome
task of maintaining active curbside units and providing
power to them. Instead of active devices locations, PONs
use small passive optical splitters, located in splice
trays, and deployed as part of optical fiber cable
plant.
-
Being optically transparent
end-to-end, PONs allow upgrades to higher bit rates or
additional wavelengths.

Customer Premises equipment,
connected to the Central Office via a Passive
Optical Splitter. It is a single integrated fiber
termination device located at the subscriber’s
home, terminating the EPON and presenting native
service interfaces to the user.

Datasheet
(PDF) |
Central
Office end equipment, which is directly connected
to the WAN link at the service- provider’s side,
capable of singly managing and dynamically
allocating bandwidth across up-to 32 connections
spread over a 20 km radius, all on a single
full-duplex fiber link, acting as an interface
between EPON and backbone network.
