The AK355E Compact Central Office Unit enables the point-to-point transport of high-quality, high bandwidth Carrier Ethernet services over bonded copper pairs. The AK355E provides 50 Mbps of symmetrical bandwidth capable of delivering carrier-grade services to 12 Kft/3.7 Km and beyond. The hardened unit is capable of providing line powering to an AK525RU Compact Remote Unit over the same pairs of copper that carry the data.
The AK355E works in conjunction with the AK525RU Carrier Ethernet Compact Remote Unit. Environmentally hardened for both inside and outside plant deployment scenario, the compact CO unit facilitates deployment in Central Office locations where space is at a premium. Its compact size enables service providers to overcome the common challenges with respect to space availability, while it’s robustness make it possible to deploy in existing outside plant cabinets with minimal modifications.
Positron’s signature FlexStream functionality enables the AK355 and AK355E to run either in symmetric or asymmetric mode with a simple software command. It allows service providers to dictate how much bandwidth is allocated to downstream vs. upstream traffic - an essential tool for ensuring precious bandwidth is used as efficiently as possible.
The AK355 can be configured as either a 100 Mbps Ethernet or a 45 Mbps DS3 product. This powerful combination of capabilities makes the AK355 the perfect product to support service provider network migration strategies. The AK355E supports Ethernet functionality and can be configured to deliver up to 100 Mbps. The AK355 and AK355E systems consist of 1RU high Central Office and Remote units for 19” and 23” racks or for wall mounting. They are environmentally hardened and the Remote units can be either line or locally powered.
Unlike other bonded copper-based broadband systems, the AK355 and AK355E deliver services that can co-exist in the same binder groups with ADSL and HDSL. This advantage exists because both systems are T1.417 spectrally compliant at bit rates and reaches that G.SHDSL based products cannot meet without the need for expensive and cumbersome repeater devices. The AK355 meets all DS3 standards. When the systems are in Ethernet mode, they are compliant with IEEE 802.3ah EFM, IEEE 802.1 and 802.3 LAN standards. They also comply with Metro Ethernet Forum MEF9/MEF14.
The first broadband over copper products to utilize patented MIMO on DMT technology, the AK355 and AK355E achieve up to 10 times more bandwidth when compared to existing symmetric DSL technologies. Utilizing Positron’s breakthrough multi-channel signal processing techniques embodied in the hardware and software, the AK355 and AK355E can transport more bandwidth over longer distances on fewer pairs than any other technology. This significant improvement is achieved by overcoming traditional copper transmission interferences such as self cross-talk, alien cross-talk and noise. The superior performance lets providers deliver more bandwidth and reach up to three times more customers.
The AK355 and AK355E dynamically compensate for individual copper pair failures. If a copper pair fails, the systems automatically adjust the other copper pair margins to compensate for the loss. This allows any pair to protect all pairs in a bonded group.
The systems can be managed by Positron`s Element Management Software (AKEMS) and AktinoView (GUI software) or via a Command Line Interface (CLI). The systems interoperate with standard Network Management Systems to provide comprehensive performance monitoring for both the transport physical layer and Ethernet or DS3**.* 24 AWG copper pair
