A:
Yes. This DWDM module uses a cooled EML laser tuned precisely to 1551.72nm (193.20 THz) on the 100GHz ITU C-Band grid. Please verify that your existing Mux/Demux tray maps this wavelength to its port labeling (commonly designated as Channel 32 in many C-band numbering schemes). As long as the tray supports this ITU channel, passive multiplexing will work seamlessly. By

In a carrier PoP batch rollout, all LS-DW3210-40I DWDM SFP optical transceivers passed eye‑pattern and spectrum checks on our 100 GHz grid, with low crosstalk through the mux/demux and no dropouts during thermal cycling; the industrial‑grade construction and tight channel spacing make it a reliable choice for dense DWDM deployments. We ran them through wide temperature swings in outdoor cabinets and the link stayed up with stable optical margins, which is exactly what we need for remote sites. The LC duplex connectors seated cleanly in our patch panels, and the modules reported consistent telemetry back to our monitoring stack. For large‑scale builds, this series gives us the repeatability and resilience we expect from carrier optics.

Procuring native optics for our multi-node DWDM transport project was going to blow our budget. Swapped in these LS-DW3210-40I 40km 10G DWDM modules and they synced up immediately at 10Gbps. Digital Diagnostic Monitoring lets us track optical Rx power levels in real time. Smooth transaction and straightforward deployment.

Needed a reliable 1551.72nm 100GHz module for a 35km point-to-point interconnect between two aggregation nodes. Received Tx power and Rx sensitivity fell well within the specified attenuation margins over standard duplex LC SMF cabling. No optical signal extenders or re-amplification required! Will definitely reorder for our next phase expansion.

Installed these units into our street cabinets for smart city surveillance backhaul links. Cold boots in sub-zero morning temperatures presented zero issues. The transmitter launch power and receiver sensitivity hit exact specs across our 30km single-mode run. Exactly what we needed for hardened outdoor edge deployments.

Deploying these 10G DWDM optics in unconditioned outdoor cabinets demands true industrial-grade hardware, and this -40°C to 85°C rated transceiver delivers. We monitored the C32 (1551.72nm) center frequency during extreme thermal cycling, and the internal stabilization kept the wavelength locked precisely on the 100GHz grid with no drift or link flapping. The ruggedized design handles sub-zero cold starts and peak summer heat effortlessly. For backhauling traffic from hardened edge switches over 30km+ SMF runs, this module's thermal budget and optical stability are outstanding.

This C32 DWDM module passed our 35km link tests with perfect optical power levels and instant DOM polling. However, import customs paperwork held up the package at the border for three extra days. Great hardware, but allow extra transit time for overseas shipping.
