Optical Transponder

DQT 400

DQT 400 Optical Transponder

Product Overview

The DQT400 is part of XKL’s DarkStar DWDM Transponder family of products, and is based on XKL’s DarkStar architecture, the foundation for addressing today’s IT challenges and scalable growth. These systems enable 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 DQT400 utilizes the latest pluggable coherent technologies to enable metro and long-haul connectivity for high-speed data networks. DQT400 systems install in under 30 minutes and are available in 1 rack unit (1U) or 2 rack unit (2U) configurations.

The DQT400 utilizes the DarkStar DMD Mux/Demux in order to aggregate up to 48 channels at 400G per channel, or 96 channels at 100G per channel, on a single fiber pair. Alternatively, the DQT400 can provide alien wave injection into an existing customer network. The DQT400 systems are fully tunable and allow for a customer to grow their network to 19.2Tb in 5U of rack space. A 12-channel DQT400, transporting 4.8Tb of bandwidth, uses only 470W.

Network administrators can deploy and commission these systems 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.

  • 1 Year hardware warranty
  • Zero cost software updates
  • Zero license fees
  • Ultra-high Bandwidth, 1.6Tb per DQT400-4 system
  • Highly scalable systems, stackable up to 4.8Tb connectivity
  • Low-power, minimal cooling, and a compact (1U) footprint

XKL’s DQT400 solution is fully capable of meeting the demands of today, with scalability to meet the network capacity requirements for the future.

Technical Features
