AEM Optical Line Termination (OLT)
Ethernet Over Passive Optical Networks
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.
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.

AEM Optical Network Terminal (ONT)
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.
