Optical Transponder

DQT 10

DQT 10 XKL Transponder

Product Overview

The DQT10 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 aggregatation of 1G – 10G services, including optical amplifiers for extending network reach, protection solutions, and other optical components that are required for any optical network.

An extension of the DQM10 family of DWDM systems, the DQT10 muxes waves outside of XKL’s typical integrated chassis, thereby allowing network growth to 96 channels and augmentation of existing networks via alien wave injection. The DQT10 systems are factory configured for 120G, 240G, or 360G of transport, making them ideal for point-to-point applications, data center interconnect, as well as for those who are unsure about future bandwidth requirements.

DQT10 systems install in under an hour and are available in 1 rack unit (1U) or 2 rack unit (2U) configurations. A typical DQT10 (i.e., 12 DWDM channels) uses 90 watts of power, and has a data propagation latency of 20 nanoseconds (ns) per system. 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 DQT10 system, leaving network administrators with confidence in their deployments.

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



Technical Features

Integrated System Architecture:

  • DWDM Solution.
  • No layer 2/3 protocol processing, no data buffering. This is both a
  • reliability and security feature; impossible to access transport data through management network.

System Level Features:

  • Hot-swap components:
  • 1+1 redundant power supplies, supports AC and DC.
  • Redundant fans.
  • Laser transceivers: C-Band Tunable SFP+, QSFP+, and Optical
  • Service Channel (OSC).
  • Field-replaceable dual flash storage modules; one is write-protected.
  • Hitless software upgrades—no customer data loss.
  • System-wide watchdog timer to ensure software response.

Client Services:

12 Channel: 3 x QSFP +
24 Channel: 6 x QSFP +
36 Channel: 9 x QSFP +

Line Side:

12 Channel: 12 x tunable SFP+
24 Channel: 24 x tunable SFP+
36 Channel: 36 x tunable SFP+


120G per chassis; grows in 120G increments up to 360G per chassis. (A DQT10 requires the DMD-A or DMD-P Mux/Demux.) A network based on the DQT10 and DMD solution can grow to 48 or 96 channels. Alternatively, the DQT10 can provide alien wave injection into an existing customer network.

Field Replaceable Units:

Field-replaceable dual flash storage modules; one is write-protected.
Hot-swap laser transceivers: C-Band Tunable SFP+, QSFP+, and Optical Service Channel (OSC).
Hot-swap power supplies (1+1 Redundant).
Hot-swap fan units.

Supported Topologies:

Protected (using DMD-A)
