DQT 100

DQT-100 Optical Transponder

Product Overview

The DQT100 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.

The DQT100 comes with either one or two 100G DWDM channels. The 100G data channel can use either tunable 100Gbps coherent CFP transceivers or non-DWDM short-reach CFP transceivers. These systems enable customers to soft-configure the aggregation of 10G Ethernet services.

The DQT100 utilizes the DarkStar DMD Mux/Demux in order to aggregate up to 96 wave lengths on a single fiber pair. Alternatively, the DQT100 can provide alien wave injection into an existing customer network. The DQT100 systems are fully tunable and allow for a customer to grow their network to 9.6 terabits of line-side bandwidth. The DQT100 solution includes a powerful aggregation scheme based on statistical multiplexing.

This approach to data aggregation optimizes channel utilization, provides bandwidth shaping controls, and gives the customer complete control over their data transport. Under the instantaneous demands of real-world internet traffic, statistical multiplexing leverages the statistics of real-time demand, allowing many more users to transmit their data packets over a shared channel than would normally be the case if a static aggregation approach, such as time-division multiplexing, were employed.

As a result, statistical multiplexing can help lower the cost of building and maintaining an optical network. DQT100 systems install in under an hour and are available in 1 rack unit (1U) or 2 rack unit (2U) configurations. A typical DQT100 (i.e.,1 port) uses 164 watts of power. 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. All the complexities of building an optical network are handled by the DQT100 system, leaving network administrators with confidence in their deployments.
