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 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.

International transit took a little longer during the customs handoff than we had planned. The package reached us intact, with each optic kept in its own protective anti-static packaging.

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.

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.

We needed a 1563.04nm DWDM transceiver for a point-to-point 10GbE fiber extension between offices. This module was recognized quickly and the 10G traffic has been stable. Good option for teams building a cost-conscious DWDM fiber network.
