Attributes of Traditional LH DWDM

• Designed for point-to-point transportCannot be deployed in ring topology

• Fixed OADM (usually 10–20% of total traffic)

• Cost model is for >40 channelsHigh first cost for amplifiers and filters

• Expensive Raman amplification to go >1000 km

• Large footprint and power consumption

• Cumbersome new wavelength provisioning

• Inability to support line-rate 10 GE LAN PHY (no G.709)Constrained by older, proprietary FEC coding


Attributes of Traditional Metro DWDM

• Primarily designed for 2.5-Gbps networksGrowth to 10-Gbps requires more amplifiers or OEO Regen

• Typically deployed in >200-km applicationsGrowth to >200-km requires more amplification or OEO RegenNo FEC on transponders

• Fixed OADM (usually up to 100% of total traffic)• Very low-cost model

Very few amplifiers requiredChannel or band-based architecturesNo FEC or tunabilityOSC and controllers are not redundant

• Small/medium footprint and low power consumption• Cumbersome new wavelength provisioning

Manual attenuators and no automatic power controlNo drop and continue because of band architectures


Cisco ONS 15454 MSTP Features

• 32 channels @ 100-GHz channel spacing in C-band• Hardware ready for 64 channels @ 50-GHz spacing in C-band• 1000-km nonregenerated optical performance• Transparent transport of any service from 8 MB to 10 GB• Muxponding of OC-n and data interfaces• SFP and XFP-based transponders• Tunable transponders over multiple channels• G.709-based transponders with full performance monitoring• Complete wavelength reuse with drop and continue• Automatic configuration, setup, and maintenance• Low power consumption and footprint • Lowest first cost and lowest total cost


Traditional DWDM Metro Solution

Traditional DWDM• Fixed channel filters

require specific part numbers.

• Current functions do not support dynamic traffic management.

• Systems use passive DWDM components for signal aggregation.

• Optical span power management is a manual process.

• Channel balancing is a manual process.

• Adding nonengineered λservices is intrusive

• Sparring is inefficient

Intelligent DWDM: Automatic Network Setup

Automatic Network Setup from Design to Deployment• MSTP design tool is used to design, verify and order

MSTP networks.• Output of MSTP design tool is used to automatically set

up network.MSTP design tool configuration file used to:

Automatically set all eVOA and amplifiers Identify card names and slot assignments for techniciansGive port-to-port fiber connections to technicians

• 1510-nm OSC is used to establish “DCC-like” link to all nodes.OSC gives full automatic topology discovery.OSC allows user to provision and monitor all cards and circuits.


Intelligent DWDM: Automatic Power Control

Automatic Power Control (APC)• Automatically monitors and adjusts the optical

power of amplifiers• Automatically corrects gain as needed without

manual intervention• Maintain power levels to avoid nonlinear effects• Manages fast effects directly at amplifier level • Manages aging at network level through

information exchange between nodes• Equalizes power on a per-channel basis at

network ingress


Intelligent DWDM:Wavelength Path Provisioning

Wavelength Path Provisioning• Optical circuits are managed in the same way as

SONET/SDH circuits.

• Element management system is used to provision A–Z SONET/SDH and wavelengths.

• Transponders are tuned to the correct wavelength.

• Incorrect circuits are not allowed if wavelength is unavailable.

• Wavelength performance monitoring is provided by G.709.

Description: WSS provides blocking and drop port tunability.

• Scaling from 8 to 32 is accomplished by adding units, 8 channels at a time.

• WSS offers the ability to predeploy ITU interfaces without knowledge of where that wavelength will originate and terminate, thereby lessening Txpdr-ROADM recabling.

• WSS offers automated bridge and role for churn.
