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 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.

The real-time DOM information is the main reason we selected this 10G SFP+ 40km optic. We can track module temperature, voltage, transmit power, and receive power before a marginal fiber issue turns into an outage. It has been reliable in our rack environment.

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!

Needed specific Channel 18 (1563.04nm) transceivers to fill an open port on our 16-channel DWDM passive multiplexer panels. Dropped this module in, connected the duplex LC SMF patch cable, and instantly established a stable 10G Ethernet bridge between two remote data center racks. Digital Optical Monitoring parameters integrated natively into our SNMP collector system.

Installed several of these 10G DWDM SFP+ optics in a metropolitan access network. The 40km rating gave us enough margin for our route, and the duplex LC connector matched the patching already in place. TX and RX values were visible through the switch diagnostics, which saved time during turn-up.

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.

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.
