A:
No. In a CWDM MUX/DEMUX system, wavelengths must be matched to the specific filter port. You must use a 1350nm CWDM module on both ends of that specific channel, or route it through a 1350nm CWDM filter port. By

The LS-CW3510-40I module integrates a Cooled EML (Electro-absorption Modulated Laser). The internal cooling mechanism keeps the wavelength stable on the 1350nm CWDM grid across the entire -40°C to +85°C range, preventing adjacent-channel interference. By

Yes, as long as your CWDM MUX/DEMUX supports the standard 20nm grid (1270–1610nm). 1330nm and 1350nm are separate channels and won’t interfere. By

We built a 10G network for a manufacturing plant, connecting machines and cameras across 18km of fiber. The -40 to 85°C temperature range was critical since some equipment sits in unheated facilities. The 1350nm CWDM wavelength doesn't interfere with our existing 1310nm network. The DDM data feeds into our monitoring dashboard, so we can track fiber health in real-time. These modules work alongside other brand equipment in our network ring without any compatibility issues. We've been running at full 10G capacity for a month with zero packet loss. The stable wavelength keeps our CWDM system running smoothly.

We installed these CWDM SFP+ modules to connect security systems, flight displays, and baggage handling across three terminals. The 1350nm CWDM channel fits our existing wavelength plan without conflicts. The industrial temperature rating handles our rooftop equipment enclosures through seasonal extremes. DDM monitoring lets our network team check link status remotely without site visits. After 2 months of 24/7 operation, all 22 units are still performing flawlessly. The 40km reach easily covers our entire airport campus.

Our city deployed these modules to connect traffic cameras, emergency services, and municipal buildings over a 10G fiber ring. The 1350nm CWDM slot integrates cleanly with our 18-channel mux system. The industrial temperature range handles our outdoor street cabinets through winter and summer extremes. We appreciate the real-time monitoring capability through our network management system. The 40km reach covers our entire metropolitan area with plenty of margin. After several months of operation, we've had zero module failures across 35 units.

We deployed 48 of these LS-CW3510-40I modules in a 10G CWDM ring for our metro network. The 1350nm wavelength slots cleanly into our 8-channel CWDM grid. Over 2 months, we've seen zero wavelength drift, thanks to the cooled EML laser. The industrial temp range (-40 to 85°C) is critical for our outdoor handhole enclosures, which see extreme seasonal swings. DDM/DOM integration with our NMS (via SFF-8472) gives us real-time TX/RX power, temperature, and bias current telemetry. We've caught two instances of fiber degradation early by monitoring RX power trends. For the price, these are hard to beat for industrial CWDM deployments.
