Optical Muxponder

DQM 400

Product Overview

The DQM400 is part of XKL’s DarkStar DWDM Muxponder family of products, and is based on XKL’s DarkStar architecture, the foundation for addressing today’s IT challenges and scalable growth.

This system enables customers to soft-configure the aggregation of 100GE and 400GE services. Network managers only need to swap the client optics in order to migrate from 100GE to 400GE. There are no licensing fees or additional costs to enable the 400G channels.

The DQM400-4 utilizes the latest pluggable coherent technologies to enable metro and long-haul connectivity for high-speed data networks. The DQM400-4 system installs in under 30 minutes and is available in 1 rack unit (1U) or 2 rack unit (2U) configurations.

A network based on DQM400 systems can be expanded to 48 channels of 400G. Growth starts by adding client and DWDM transceivers to the DQM400. Growth beyond 12 channels is accomplished by stacking DQT400 systems, and cabling to the expansion ports of the DQM4-400. The DQM400 contains the Mux/Demux filters and amplifiers, which are shared with the DQT400 systems.

The DQM400-4 contains the Mux/ Demux filters and amplifiers that are shared with the DQT400-4 systems. Network administrators can deploy and commission this system in a fraction of the time it takes to deploy traditional optical transport equipment. Setting up the management network, as well as configuring services, are done in minutes.

Zero cost software updates.
No licensing fees.
Simplicity, reliability, durability.
Highly scalable solutions.
