Optical Muxponder DSM 10-5R

Product Overview

The DSM10-5R 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.

The DSM10-5R provides 1G – 10G services through ten softconfigurable channels—set to 5 channels East, 5 channels West. These systems include optical amplifiers for extending network reach, filters, protection solutions, and other optical components that are required for any optical network.

A network based on DSM10-5R systems can grow to 40 channels (400G) by adding the DarkStar Mux/Demux (DMD), making them ideal for point-to-point and rings, data center interconnect, as well as for those who are unsure about future bandwidth requirements. DSM10-5R systems install in under an hour and require only 1 rack unit (1U) of space.

A typical DSM10-5R uses between 66 and 83 watts of power, and has a data propagation latency of 20 nanoseconds (ns) per system. The DSM10-5R is a DWDM appliance. As such, 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 DSM10-5R 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:

  • Fully integrated optical components including DWDM Mux/Demux
    filter, Erbium-Doped Fiber Amplifier (EDFA), Dispersion Compensation
    Module (DCM)
  • 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: 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.
