The 40km DWDM SFP+ modules were installed as part of a campus backbone expansion. We had existing SMF cabling and a planned C21 channel, so keeping the same fiber infrastructure was important. The 1560.60nm wavelength matched our design, while the 10.7Gbps maximum data rate supports our 10G Ethernet traffic comfortably. We also checked TX/RX power and receiver sensitivity during commissioning. So far, these have been reliable workhorses.

Good fit for our outdoor network cabinets. The -40 to 85°C operating range was one of the reasons we selected the industrial version. We ran it through a temperature test before deployment and the link stayed stable.

Price is reasonable for a 40km industrial DWDM SFP+. We used it on an SMF campus link and performance has been good. The only thing I would improve is having clearer labeling on the individual packages for larger orders. The modules themselves have been reliable. :)

This was part of a multi-vendor compatibility test involving Cisco and Arista switches. The module was recognized correctly and the 10G SFP+ link negotiated without any strange behavior. We also checked optical readings during burn-in. Nice option for keeping a DWDM rollout within budget.

Used these for a small batch deployment between aggregation switches and remote cabinets. The 40km single-mode fiber rating gives us plenty of margin for our actual route.

We used the LS-DW2110-40I for a 40km fiber backhaul between an access site and the main network room. The 10.7Gbps capability gives enough headroom for our 10G service, while the Duplex LC interface works with our existing patch panels. No complaints so far. :-)

Our telecom team needed a DWDM C21 optic for a long campus connection without changing the existing SMF plant. This module matched the 1560.60nm requirement and gave us a clean 10G link over the route. Pretty straightforward install.

We bought this as an OEM-compatible 10G SFP+ option for a mixed-vendor lab. Tested it across Cisco, Juniper, and Dell gear during the rollout, and the module behaved as expected. DOM readings were useful during commissioning too.

We ordered a small batch first for a multi-brand interoperability test. Our lab setup included Cisco, Juniper, Arista, and H3C equipment, plus standard single-mode fiber and DWDM components. The LS-DW2110-40I was detected correctly, delivered a stable 10G service, and gave us the optical monitoring information we needed during validation. After the test passed, we used the same model for the production rollout.

For a network refresh, we needed a 40km DWDM SFP+ optic that could work across multiple switch brands. We tested these against Cisco, Juniper, Dell, and Arista equipment before placing the full order. The compatibility results were good, and the 10G links passed our traffic and stability checks. The industrial temperature range also helped for our less-controlled equipment rooms. =)
