DZS MXK-190 1U GPON OLTzhone mxk 190

Compact, High-Performance 1U GPON OLT

DZS's New MXK Terabit Access Platforms a truly scalable solutions for high-bandwidth applications

MXK-19x, MXK-19x-10GE


The DZS MXK-190 provides next generation 1U GPON OLT features in a compact, hardened form-factor that makes it easy and cost-effective to deliver uncompromising triple play services throughout the serving area. Models are available with 4 or 8 GPON Ports. The ITU-T standard GPON technology provides 2.5Gbps downstream and 1.25 Gbps upstream bandwidth over a passive optical network on each of the 4 or 8 ports per unit.

GPON provides one of the most cost-effective ways for operators to deploy fiber-based services to the home, business, or node. With GPON splitters that can be co-located with at the CO or installed remotely in the network, the service provider can choose the network architecture that finds the right balance between capital cost optimization and scalability.

As part of the DZS FiberHome portfolio targeting the traditionally challenging and expensive service locations for residential and business users, the MXK-190 platforms' non-blocking architecture and intelligent processing enable GPON networks to deliver uncompromising quality for the full range of multi-play services, from multiple HDTV streams, video on demand, and video conferencing, to voice and high-speed internet access.

This MXK-190 design allows easy deployment in remote cabinets and space constrained central offices. The MXK-190 platforms offer unmatched bandwidth with non-blocking capacity while leveraging DZS’s well-proven SLMS access operating system for sophisticated service intelligence.

DZS's SLMS (Single Line Multi-Service) access operating system provides intelligent functionality across all the company's hardware products. Driven by 8 years of experience in commercial operation and collaboration with 700+ service providers worldwide, DZS's SLMS software delivers functionality critical to today's access networks in advanced networking, quality of experience, voice, security, and management.

Ease of Management

The MXK-190 provides simple yet powerful management facility via CLI, embedded Web GUI along with complete ZMS integration. The easy-to-use DZS Management System (ZMS) provides OSMINE-certified management and provisioning across the access network, from ONU/ONT to the Central Office OLT. The MXK-190 is fully remote managed, allowing carriers to reduce service turn-up intervals, reduce truck rolls, and ultimately, improve customer service.

DZS’s MXK-190 also includes Smart OMCI™, DZS's unique approach to GPON ONT configuration and management. To improve ease of use for service providers, the Smart OMCI modules present a comprehensive, intuitive interface on top of a 100% standard-compliant and proven interoperable implementation of the ITU G984.4 OMCI protocol. This interface provides the behind-the-scenes intelligence required to simplify the process of adding new or changing ONT models, service definitions, and configurations, all without OLT software upgrades. DZS has participated in the FSAN Interop plugfest conducted by ETSI, which confirms the interoperability of the Smart OMCI implementation.

The MXK-190 yet supports DZS's EZ Touch Provisioning extending ZMS element and network management capabilities, which have been mainly focused on core network elements like the MXK™ and MALC™, to the edge of the network where it cost-effectively manages and provisions the subscriber-facing features of DZS manufactured GPON ONTs.

Triple Play Services

The MXK-190 includes high-performance packet switching with advanced IP capabilities to deliver secure, reliable, and efficient voice, data, and video services. Now service providers can offer compelling bundles of multi-line voice, high-speed Internet access, and multi-set IP video (including HDTV) over their existing fiber infrastructure.

Optical or Copper Transport

The MXK-190 provides multiple SFP-based and RJ45 Gigabit Ethernet uplink ports, supporting both copper and fiber, as well as fiber XFP-based 10Gigabit Ethernet uplink ports to provide simple cost-effective transport. The uplink ports allow daisy-chained linear, RSTP (802.w), Ling Aggregation with LAG/LACP (802.3ad) or ring deployments supporting standards-based EAPS.
