What is the maximum transmission distance of the SFP-25G-SR-C?

It supports up to 100m over OM4 multi-mode fiber and 70m over OM3 MMF.

Can I use this module with single-mode fiber or APC connectors?

No, it is designed for multimode fiber with standard PC/UPC LC connectors; single-mode or APC will cause high loss and damage risk.

What is the typical power consumption of the SFP-25G-SR-C?

It consumes less than 3.3W under normal operating conditions.

Is the module MSA-compliant and interoperable with other brands?

Yes, it complies with SFP28 MSA and IEEE standards, ensuring interoperability with most MSA-compliant 25G switches and NICs.

Is the internal mechanical latch robust enough to handle frequent daily patch reconfigurations in a staging lab?

Yes, the secure Duplex LC bail latch mechanism is rigorously cycle-tested to ensure repeated clean connections without physical drift.

If our data center cooling system suffers a temporary failure, what is the maximum safe storage/idle temp threshold before internal optics degrade?

The transceiver housing can withstand non-operational storage temperatures ranging from -40°C up to 85°C without warping the internal optical array.

We have a critical cross-connect run that measures exactly 90m over OM4 fiber. Is that pushing the absolute edge of this optic's link budget?

Not at all, as long as your multi-mode fiber faces are clean and your patch panels are within normal insertion loss specs, it will hold a flawless 25G link.

Good cheap 25GBASE-SR optics for enterprise switch deployments. The DOM functions perfectly, reporting accurate laser metrics. Deducted one star because delivery to our UK site took an extra two days due to customs clearance delays. The modules themselves are perfect though.

Upgraded our storage area network (SAN) from 10G to 25G using these LS-MM8525-S1C optical transceivers. The difference in throughput is night and day. No overheating issues in our standard 0-70°C commercial environment. clean and stable.

Excellent 25G SFP28 transceivers for server-to-switch interconnects in our regional data center. Checked the DDM info via CLI, and Tx/Rx optical powers are completely within nominal ranges. Will definitely look into LINK-PP for our next bulk fiber hardware procurement.

Our company recently migrated its primary backup cluster to a dedicated SAN fabric. We chose these 25G SFP28 multi-mode optical transceivers to bridge the 80-meter distance between our backup arrays and the core switch. Using OM4 fiber, the links established instantly at 25Gbps. We pulled the DDM data via CLI, and the optical output levels are perfectly optimized to prevent saturation while ensuring high signal-to-noise ratios. The modules fit snugly into our SFP28 ports with no loose play. The low power consumption is definitely a bonus for high-density networks where thermal management can be tricky.

Modules perform exactly as advertised, hitting full 25G line rates over our 60m OM3 fiber runs. My only tiny complaint is that the pull-tab latches are a bit stiff on first insertion compared to our old 10G optics. They seat securely though, and DOM telemetry is perfect. Good budget choice.

Using these for internal server room patching between our main firewalls and core switches. The 100m distance limit on OM4 is perfect for our layout. Total peace of mind with the native DOM monitoring support. Will buy again.

We had a critical requirement to upgrade our internal corporate SAN to handle multi-stream 4K video editing and large database replication. Our setup involves an array of servers connected to a central storage array via OM4 fiber. These 25G SFP28 transceivers were a drop-in replacement for our aging 10G modules. The link came up at full 25Gbps instantly without any manual configuration or speed forcing required in the OS. We monitored the DDM/DOM attributes via the switch interface for a week; the operating temperature remained perfectly stable at 41°C. The duplex LC connector gives a solid, reassuring 'click' when fully seated, preventing accidental disconnects during routine cable management in the rack. Having reliable, cheap 25GBASE-SR optics available saves our IT budget that can be reallocated to raw storage capacity. A+ product.

We deployed these commercial-grade 25G SFP28 modules across our core network infrastructure to support an influx of high-bandwidth containerized applications. Operating inside an air-conditioned datacenter environment, these modules hold an optimal temperature profile, never exceeding 43°C even during peak traffic periods. The multi-mode fiber 100m capability allowed us to easily connect across adjacent rows of server racks without needing single-mode conversion. The Duplex LC physical connectors match perfectly with our high-quality patch cords, ensuring zero alignment loss. The DOM feature works cleanly out of the box with zero configuration needed. Very impressed with the engineering quality of these transceivers.

I finally decide to give LINK-PP Ethernet port a try, since they are not as expensive as an original module. The result makes me very satisfied. They work well with very low insertion loss on our equipment, and the connection is also very firm.
