Can this 1270nm CWDM SFP+ module work in a Cisco switch with an existing 40km single-mode fiber link?

Yes, the product page lists Cisco compatibility, and the module is designed as a 10G SFP+ CWDM optic with a 1270nm wavelength, Duplex LC interface and SMF support up to 40km. For a production deployment, we would still recommend confirming the exact Cisco switch model and required CWDM channel before ordering.

We are putting optics in outdoor cabinets. Does the industrial version actually support wide temperature conditions, and can we monitor the optic remotely?

Yes. The specified operating case temperature is -40 to +85°C. The module also supports real-time digital diagnostic monitoring, including temperature, supply voltage, bias current, TX optical power and RX optical power, which is useful for remote NOC monitoring and field maintenance.

Does the module support standard 10G applications, or is it only intended for CWDM networks?

It is designed for 10G CWDM optical systems and also lists 10GBASE-ZR at 10.3125Gbps, 10GBASE-ZW at 9.953Gbps and LTE systems among its applications. The module supports up to 10.7Gbps, uses a hot-pluggable SFP+ footprint and complies with SFP+ MSA and SFF-8472.

Used these in a small data center expansion with several racks of 10G switches. The Duplex LC interface fit our existing patch panels, and the modules were detected correctly across different switch brands during our compatibility checks. DOM is especially useful for ongoing maintenance. :)

I bought these for a 10G fiber connection between a main office and a remote facility. The link came up immediately, and DOM gave us enough information to verify the optical condition without connecting a separate test instrument. Very practical for field support. :-)

The shipment arrived a day later than our original expectation, and one package had a slightly dented outer box. The modules were protected inside and worked correctly after installation. Performance on the 10G 40km SMF link has been fine, so the issue was only with delivery/packaging.

Great fit for our industrial cabinets. The -40 to 85°C operating range was one of the main reasons we selected this model for outdoor network enclosures. We also like having DOM available for checking temperature, voltage, TX power and RX power remotely.

We needed a long-reach 10G SFP+ transceiver for a campus fiber backbone without replacing the existing SMF. The 1270nm CWDM wavelength worked with our channel plan, and the 40km rating gave us plenty of margin for the actual link distance. Installation was straightforward.

Packaging was a little more basic than expected, but the modules themselves arrived intact and worked normally. We tested the 10G link with single-mode fiber and verified DOM readings after installation. No performance concerns so far.

We use CWDM to carry multiple wavelengths over the same single-mode fiber infrastructure. This 1270nm SFP+ module integrated cleanly into the existing setup and maintained a stable 10G link. The SFF-8472 diagnostics are useful for our NOC team because we can monitor optic health remotely.

For a regional network upgrade, we needed 10G CWDM optics that could work across different OEM switch platforms. These modules made the procurement much easier because we could standardize the same optic across multiple compatible environments. The DOM readings are also helpful when monitoring fiber attenuation and receive levels.

We installed a pair on a long campus fiber route connecting an aggregation switch to a remote building. The 1270nm wavelength and Duplex LC interface matched our existing CWDM equipment, so there was no need to change the fiber plant. Link stability has been excellent under normal production traffic.

I spent a lot of time looking at the 1000 Base-T Optical Transceiver Module and finally decided on l-p.com. The website was very well done so that eased my mind a bit. When the 1000 Base-T Optical Transceiver Module arrived I was pleased that they looked just as good as it did on the website and worked without problem.
