We need to deploy 50 units for a 5G wireless fronthaul network. Does it meet the eCPRI latency requirements?

Yes, it is fully optimized for 25G eCPRI protocol options, delivering the ultra-low latency and low jitter that cell site backhauls require.

What is the maximum power consumption per port when all 48 ports on a leaf switch are fully loaded with these LS-SM3125E-10I SFP28 transceivers?

Each transceiver module draws less than 1.2W, ensuring your core switch stays cool and well within its aggregate thermal power budget.

Can this SFP28 transceiver operate at 10Gbps, or is it strictly for 25Gbps networks?

This is a dual-rate transceiver that supports both 10Gbps (10GBASE-LR) and 25Gbps (25GBASE-LR) speeds, allowing for easy network migration.

Highly recommend these for any enterprise network migration. We are running them at 10G right now on older switches and plan to toggle to 25G next year when we upgrade the core routers. Backward compatibility is great.

Using these SFP28 optical modules in outdoor pole-mounted enclosures where temps fluctuate wildly. The industrial-grade rating gives us peace of mind. So far, 2 months of continuous uptime with zero link flaps or frame drops.

We operate an ISP network and use these for 10G/25G dual-rate aggregation links. The ability to switch speeds seamlessly without swapping hardware makes network scaling so much easier. Excellent 1310nm single-mode SFP transceiver modules.

We replaced several failing 10G links with these 25G SFP28 modules for our high-frequency trading desk. The latency reduction was noticeable, and the 1310nm wavelength works flawlessly over our dark fiber lease.

Transceivers look and feel high quality, and 25Gbps throughput is incredibly stable. My only complaint is that the protective rubber dust caps were a bit loose on two of the modules inside the package. Cleaned the connector interface before installation just to be safe, and they work perfectly.

Perfect solution for outdoor industrial deployments. We manage municipal traffic monitoring networks where edge switches are housed in non-climate-controlled street cabinets. Standard commercial optics fail when ambient temps cross 70°C, but these industrial wide-temperature modules have run continuously at an internal module temp of 75°C without a single CRC error or link drop. The DOM telemetry allows us to track thermal trends before they become critical. Highly recommended for ruggedized infrastructure and smart city backhaul projects.
