Optical Muxponder

DQM 10

Product Overview

The DQM10 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.

These systems enable customers to soft-configure the aggregation of 1G – 10G services, including optical amplifiers for extending network reach, filters, protection solutions, and other optical components that are required for any optical network.

A network based on DQM10-12 systems, 12x10G channels, can grow to 48 channels. One way growth is accomplished is by stacking DQT400 systems, and cabling to the expansion ports of the DQM10-12. This creates a solution of 10G and 400G DWDM channels.

The DQM10-12 contains the Mux/Demux filters and amplifiers that are shared with the DQT400 systems. DQM10 systems install in under an hour and are available in 1 rack unit (1U) or 2 rack unit (2U) configurations. A typical DQM10 (i.e., 12 DWDM channels) uses 90 watts of power, and has a data propagation latency of 20 nanoseconds (ns) per system.

The DQM10 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 DQM10 system, leaving network administrators with confidence in their deployments.

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.
