1.Dave, service provider engineer in Texas
"Metro Ethernet network uses these for 40G aggregation. The 10km reach covers our POP-to-POP connections. The WDM technology makes efficient use of fiber. Good optical budget, stable performance. Would recommend."

2.Carlos, cloud ops in California
"Hyperscale campus needed 40G links between data center buildings. These LR4 modules with single-mode fiber work perfectly. Consistent optical power across all four wavelengths. Lower power consumption than optics we used before."

3.Wei, optical module manufacturer in Shenzhen
"We supply these 40G LR4 transceivers to telecom clients. Full testing ensures performance at 10km. Quality control includes wavelength alignment and optical power testing. Good yields, consistent quality across batches."

4.Lisa, telecom engineer in Canada
"5G transport network needed 40G aggregation. The industrial temperature version handled -40°C to 85°C. The LR4 modules with single-mode fiber work at 15km with margin. Good performance, no failures."

5.Raj, IT manager in India
"Data center interconnect between two facilities used these LR4 modules. Plug and play with HPE switches. The 10km reach covered the 7km distance. Good quality, would buy again."
