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
171717© 2004 Cisco Systems, Inc. All rights reserved.
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

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

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.
