Demands on access networks are increasing at an accelerating rate, requiring a clean-sheet approach to a truly scalable multi- service architecture. DZS’ MXK™ intelligent terabit access concentrator reflects this new approach, with non-blocking capacity of up to 3,600 100Mbps GPON subscribers or 360 1G Active Ethernet subscribers per chassis. Beyond sheer bandwidth, MXK platforms leverage DZS’s well-proven SLMS access operating system for sophisticated service intelligence, to guarantee high quality of experience for subscribers, along with ease of management to address rising costs of network operation.

The MXK delivers these fundamental advances in access networking while meeting the full spectrum of baseline carrier-class requirements for multi-service hardware and software. For residential triple play and high-bandwidth business services over any FTTx architecture, the MXK solution sets a new performance benchmark for the industry.

The MXK family offers a wide range of options for FTTx solutions. It supports Active Ethernet and GPON line cards, and interoperates with indoor and outdoor ONTs. Supporting Active Ethernet and GPON on the same chassis allows service providers to configure their networks with maximum flexibility and efficiency, using a combination of GPON splitters and dedicated fiber connections.


The MXK family includes three fully-integrated form factors:

  • MXK-319 – 19″ Rack x 3RU, with 7 slots for line cards
  • MXK-819 – 19″ Rack x 8RU, with 14 slots for line cards, 68W
  • MXK-823 – 23″ Rack x 8RU, with 18 slots for line cards). The chassis support both front and rear power options and are equipped with a cable management tray, easy fan access, and redundant power feeds.


MXK uplink cards offer a mix of multiple 10G and 1G interfaces to suit a variety of network designs. Several line rate configurations are currently available, including two different variants of 2x10G + 8x1G, as well as 6X1G. These cards provide connection points for common synchronization inputs including SyncE and 1588v2, as well as support for both copper and fiber SFPs, link aggregation, link redundancy, and the EAPS ring interface.


DZS’ SLMS (Single Line Multi-Service) access operating system provides intelligent functionality across all the company’s hardware products. Driven by experience in commercial operation and collaboration with 700+ service providers worldwide, DZS’ SLMS delivers functionality critical to today’s access networks in advanced networking, quality of experience, voice, security, and management.


To maintain tight security in the last mile, the MXK platform mounts considerable defenses, powered by all of DZS’s SLMS security features, including multicast control lists, secure bridging, broadcast suppression, dynamic IP filtering, SSH and SFTP, and RADIUS authentication.


The MXK product line integrates fully into the DZS Management System (ZMS). Using ZMS, thousands of MXK nodes can be managed from remote locations. Customer provisioning, auto discovery, alarm aggregation, and maintenance can easily be performed without any service interruption.


Unlike vendors who have dodged the complexity of the ITU’s G984.4 standard for GPON ONT management, DZS provides a simple and clean interface to a fully standards-compliant OMCI implementation. DZS’s Smart OMCI™ approach allows the MXK OLT to interoperate with any vendor’s ONT, yielding rapid ONT and service extension without OLT software upgrades. With Smart OMCI you can configure, obtain stats and support alarms on any ONT without hassle.


DZS offers a full line of outside cabinets engineered specifically to support MXK platforms. Multiple configurations are available for deployments from small to large scales, with a wide range of powering, protection, and line termination options.
