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.

  1. Allow for long reach between the CO and customer premises, operating at distances over 20 km

  2. Minimize fiber deployment in both the CO and the local loop.

  3. Provide higher bandwidth due to deeper fiber penetration, offering gigabit-per second solutions.

  4. Operating downstream as a broadcast network, PONs allow for video broadcasting either as IP video, or analog video.

  5. 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.

  6. 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.
