Q
What is the Cisco OADM EWDM Module?
A
The Cisco Optical Add-Drop Multiplexer (OADM) EWDM Module is a pluggable line-card solution that enables efficient insertion and extraction of specific wavelengths in an optical DWDM network.
Q
How does the Cisco OADM EWDM Module improve network capacity?
A
By selectively adding or dropping individual wavelengths, the module maximizes fiber utilization, increases overall bandwidth, and supports scalable service growth without new fiber installations.
Q
What are the key features of the Cisco OADM EWDM Module?
A
Key features include ultra-low insertion loss, channel-level monitoring, extender compatibility up to 100 GHz grid, and full integration with Cisco NCS and aggregation platforms for end-to-end management.
Q
Which Cisco platforms support the OADM EWDM Module?
A
The module is compatible with Cisco NCS 2000, NCS 4000, and ASR 9000 Series routers—delivering seamless integration in both metro and long-haul DWDM architectures.
Q
How many wavelengths does the Cisco OADM EWDM Module support?
A
It supports up to 80 CWDM or 96 DWDM wavelengths per fiber pair, depending on the platform and line-card configuration.
Q
What is the typical insertion loss of the OADM EWDM Module?
A
Typical single-channel insertion loss is 2.5 dB, ensuring minimal signal degradation and maintaining high optical signal-to-noise ratio (OSNR).
Q
How do I install the Cisco OADM EWDM Module?
A
Install the module into a compatible line-card slot, secure the mounting screws, connect the tributary and trunk fibers, then configure channels via the IOS XR CLI or Network Services Orchestrator.
Q
How can I monitor and manage the module?
A
Use Cisco IOS XR software or the Cisco Network Services Orchestrator for real-time wavelength alarms, optical performance metrics, and end-to-end service visibility.
Q
What are the ordering part numbers for the OADM EWDM Module?
A
Ordering codes vary by platform: NCS-2K: OADM-EWDM-1T; NCS-4K: OADM-EWDM-2X; ASR9K: OADM-EWDM-3S. Confirm with Cisco sales for regional SKUs.
Q
How is the Cisco OADM EWDM Module powered?
A
The module draws power directly from the host chassis and requires no additional external power supplies.
Q
What safety and compliance standards does it meet?
A
The module complies with CE, FCC, RoHS, and UL 60950 standards, ensuring environmental safety and electromagnetic compatibility.
Q
What is the operating temperature range?
A
Supported operating temperatures range from 0 °C to 40 °C, with storage tolerance from –40 °C to 70 °C.
Q
Can the OADM EWDM Module support dynamic wavelength provisioning?
A
Yes, when integrated with Cisco NCS and SDN controllers, it supports on-demand wavelength allocation and software-driven network reconfiguration.
Q
What are common troubleshooting steps for the module?
A
Verify fiber connections, check OSNR and channel alarms, review the IOS XR event logs, and perform a module reseat before escalating to Cisco TAC.
Q
How does Cisco OADM differ from ROADM?
A
OADM provides fixed add/drop functionality for predetermined wavelengths, whereas ROADM offers dynamic wavelength routing and colorless, directionless, contentionless flexibility.
Q
Which use cases benefit most from this module?
A
Ideal for metropolitan access rings, point-to-multipoint enterprise services, and cost-efficient wavelength expansion in existing DWDM infrastructures.
Q
How do I contact Cisco support for module issues?
A
Open a Cisco TAC case via the Cisco Support Portal at https://support.cisco.com or call your regional support hotline for expedited assistance.
