We are extending a 10G link between two factory buildings. Can this module work with our existing single-mode fiber?

Yes, the module is designed for duplex single-mode fiber links and uses a duplex LC connection. Please check that your DWDM channel plan uses C18 1563.04nm.

We need optics for an LTE backhaul project in remote locations. Is this a suitable option?

Yes, the LS-DW1810-40I DWDM module is suitable for LTE systems and other 10G optical links. Its DWDM wavelength helps carry more services over limited fiber resources.

We are installing these in outdoor RRU cabinets on LTE cell towers in Northern Canada. Can this optical module handle sub-zero winter temperatures?

Yes, perfectly. The "I" suffix in LS-DW1810-40I indicates an industrial-grade operating case temperature range of -40°C to +85°C. It is built specifically to operate reliably in unconditioned outdoor enclosures during extreme winters.

We plan to plug this module into a 100GHz DWDM Mux/Demux filter. Is Channel 18 guaranteed to be stable without wavelength drift?

Yes. This LS-DW1810-40I module uses a high-precision cooled EML laser designed specifically for 100GHz ITU C-Band grid stability. It maintains its tight 1563.04nm wavelength tolerance even under fluctuating operational loads.

We installed this DWDM SFP+ module to connect our main server room with a remote campus building. The fiber path already had several patch panels and a passive DWDM system in place, so we wanted an optic that would fit the existing channel plan without extra work. The module was recognized quickly, and the connection came online after the normal fiber checks. Since going live, the link has carried daily business traffic without unexpected drops. The DOM information is also helpful because our team can check optical power and module health from the network interface instead of sending someone onsite first. It has been a dependable choice for our campus fiber connection.

We added these modules to a multi-channel DWDM transport setup for an offsite rack row. The LS-DW1810-40I showed healthy RX power on both ends, and hot-swapping made the maintenance window very short. It is a practical 40km SFP+ solution for metro access links.

We selected this DWDM transceiver for a metro fiber project where fiber capacity was limited and several services needed to share the same route. It matched our planned optical channel and worked well with the passive DWDM equipment already installed. The duplex LC connection also made field patching familiar for the installation crew. We completed standard link checks before putting the circuit into production, then watched the DOM information during the first few weeks of service. Everything remained stable, and the module handled regular business traffic without issues.

OEM optic prices from traditional vendor channels were completely out of our budget for a secondary metro fiber ring project. Opted for these industrial 40km 10G DWDM SFP+ units instead. Transmission signal power on the 1563.04nm wavelength is crisp, and bit error rates (BER) are well within IEEE 802.3ae standards. Highly recommended for network ops on a budget!

We used this C18 DWDM SFP+ module for a protected base-station backhaul cabinet connected over SMF. Its CPRI and eCPRI support was relevant to the application, while the 40km optical budget covered the distance comfortably. Just make sure the cabinet environment remains within the specified operating range.

Our team bought a batch of these modules for a multi-site fiber upgrade. We tested them before sending equipment to each location, checked that they were recognized by the network ports, and reviewed the DOM readings during staging. The labeling made it easier for technicians to match each optic with the correct DWDM channel. In daily use, the modules have been easy to manage. We can review transmit and receive levels through our monitoring tools, which helps us spot fiber issues early. For teams handling several long-distance 10G connections, this is a practical DWDM optic with useful visibility for normal operations.

Purchased a batch of these DWDM modules for an edge node transport upgrade. Every single transceiver came individually labeled with clear ESD protective packaging and protective dust caps intact. Transmitters locked onto the C18 100GHz grid frequency without drifting. Our engineering team verified flawless optical pass-through performance during stress testing.

This is a straightforward 10Gbps DWDM optic for long single-mode fiber links. The EML DWDM design, 100GHz spacing, and LC duplex interface were exactly what we needed for our channel allocation. No drama during installation — always a win.

The module linked cleanly over SMF and provided the expected TX/RX diagnostics. Packaging was secure overall, but the outer carton had a small scuff from transit. Nothing wrong with the optic—just worth noting for bulk shipments.

We used this optical transceiver for a protected telecom cabinet supporting a backhaul connection to our aggregation location. It worked well with our DWDM equipment and matched the required channel in the project design. The LC fiber connection was familiar to our field team, so installation was quick and straightforward. We checked the cabinet environment before deployment to make sure the module would stay within its supported temperature range. After installation, the diagnostics gave our NOC team a simple way to watch the link remotely.
