4. Product Introduction & Supply Chain Strategy
The Alcatel-Lucent 1665 LNW19B is a high-capacity 10G Optical Line Interface (OLI) designed for the Metropolis DMX multiservice multiplexer platform. It serves as the primary backbone interface, enabling the 1665 DMX to aggregate TDM and Ethernet traffic into high-speed OC-192 rings. This module is vital for service providers and private network operators who require high-density bandwidth for metro-core and edge-access applications.
From a supply chain perspective, the LNW19B is a critical “Last-Time-Buy” candidate. As many SONET platforms reach maturity, securing New Surplus units is a strategic necessity to avoid the catastrophic risks associated with refurbished cards. Used LNW19B modules often suffer from degraded internal timing circuits or laser driver instability due to years of continuous 24/7 operation. By stocking New Surplus inventory, you ensure a significantly lower Total Cost of Ownership (TCO), bypassing the unplanned $25,000+ expenses related to emergency technical dispatch and ring restoration when a second-hand card fails.
5. Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
Verify the DMX shelf has the required high-speed slot capacity and that the backplane is configured for 10G throughput. Use a digital fiber scope to inspect the XFP optics and patch cords. Critical: Always wear a grounded ESD wrist strap; the high-speed Gallium Arsenide (GaAs) components on this card are highly susceptible to static damage.
Stage 2: Removal
If replacing an active LNW19B, perform a forced switch to the protection line via the Management System to ensure no traffic loss. Loosen the faceplate thumb screws and use the extractor handles to pull the module straight out of the chassis.
Stage 3: Installation (Clone & Seat)
Verify that the XFP module is properly seated in the LNW19B before inserting the card into the shelf. Slide the module into the designated high-speed slot and push firmly until the handles click into place. Secure the captive screws to ensure electrical continuity with the chassis ground.
Stage 4: Power-On & Testing
Monitor the LED indicators. The “Active” LED should stay dark until the card is provisioned, while the “Fault” LED should turn off after initial hardware stabilization. Use the CIT (Craft Interface Terminal) to confirm the module is recognized and to check the received optical power levels (dBm) to ensure they fall within the specified receiver sensitivity range.

6. Firmware/Software Versions & Upgrade Notes
The LNW19B typically requires Metropolis DMX Release 5.0 or later. If your system is running an older software load, the card may be “unrecognized” or exhibit “Version Mismatch” alarms.
Technical Note: Before swapping an LNW19B, check the “Target Identifier” (TID) and ensuring the software database is backed up. When the new card is inserted, the shelf controller may automatically push the current system firmware to the card; do not remove the module or reset the shelf during this synchronization process.
7. Frequently Asked Questions (FAQ)
What makes this “New Surplus” rather than “Refurbished”?
Our LNW19B units are sourced from unused project overstock. They have never carried live traffic and have remained in climate-controlled, ESD-protected storage. Unlike refurbished units, these have zero wear on the high-speed backplane connectors and no heat-related component aging.
Does this card include the XFP optical transceiver?
The LNW19B is the base interface card. While some may come with an XFP pre-installed, the optical transceiver is typically treated as a separate line item to allow you to choose the specific distance (SR, IR, LR) required for your fiber span.
Is the LNW19B hot-swappable?
Yes, the 1665 DMX platform supports hot-swapping. however, to maintain ring stability, we recommend performing a manual protection switch before removing a service-affecting card.
Will this work in the 1665 DMXtend (small shelf)?
Yes, the LNW19B is compatible with both the full-sized 1665 DMX shelf and the DMXtend shelf, provided there is a high-speed slot available for 10G operation.
What is the warranty for a New Surplus card?
We provide a standard 12-month replacement warranty on all New Surplus Alcatel-Lucent modules. This offers significantly higher protection than the “as-is” or limited 30-day warranties typically found with used equipment brokers.
