What benefits does Cisco DS-SFP-FC4G-LW Compatible LINK-PP provide?

It offers 4.25 Gbps Fibre Channel performance across SMF up to 10 km, featuring a reliable 1310 nm DFB transmitter, DOM for live diagnostics, and a hot-pluggable SFP form factor for easy replacement and broad host compatibility.

Does this module allow you to check its status from a distance?

Yes. Thanks to DOM, you can see real-time values for optical power, voltage, and temperature.

How far can you run the link with this module?

It can go up to 10 kilometers when used with standard single-mode fiber.

What are common applications for this module?

Typical deployment scenarios include Fibre Channel SAN systems, enterprise storage networking, switch-to-switch optical uplinks, data center interconnections, and medium-range optical backbone communication.

Can I use these with OM3 multi-mode fiber, or is it strictly for single-mode?

The LS-SM314G-10C is designed for single-mode fiber (1310nm). If your infrastructure is currently running on OM3 multi-mode fiber, you will need a different transceiver model optimized for 850nm wavelengths. Feel free to contact us if you need help matching the right model to your fiber type!

We are planning a large-scale project. Do you offer bulk discounts for orders over 100 units?

Absolutely! For large-scale deployments or bulk enterprise procurement, we offer competitive volume pricing. Please reach out to our sales team directly with your specific quantity requirements for a custom quote.

Does this module support industrial wide-temperature ranges for outdoor cabinet deployment?

This specific LS-SM314G-10C model is rated for standard commercial operating temperatures. If your project requires extreme industrial temperatures (-40°C to 85°C), please let us know so we can assist you in selecting the correct hardened version of our transceivers.

Will this LS-SM314G-10C transceiver work with my Cisco Catalyst 3850 switches?

Yes, our LS-SM314G-10C SFP modules are designed to be 100% compatible with Cisco Catalyst 3850 and most other standard MSA-compliant switches. They are fully coded to ensure seamless plug-and-play functionality.

Good quality for the price. I was skeptical at first, but it synced up with our Mikrotik routers without needing any special config.

Good performance, but the shipping took a bit longer than I'd like to get to the Midwest. Otherwise, the transceiver is solid and hasn't had any errors since I installed it.

Packaging was neat and professional. It arrived earlier than expected. Performance-wise, it's holding up well under 24/7 load in our climate-controlled rack.

I've been deploying these in outdoor, temperature-regulated cabinets for about two months now. Even with the humidity and fluctuating loads, these SFP modules have not skipped a beat. The DDM implementation is quite responsive, which is a lifesaver for identifying potential fiber degradation before it causes a full outage. They are a reliable, cost-effective alternative to expensive brand-name optics.

We swapped out some old transceivers in our server room for these. No downtime during the migration, and the 1310nm wavelength is stable. Will be buying more for the next phase.

Integrated 20 of these units into our remote edge-computing site. These modules have seen a variety of temperatures and constant data traffic. The 1310nm single-mode operation is rock-solid. Even under high traffic, the latency is negligible. They have saved our project a significant portion of the hardware budget, allowing us to allocate more funds to the switching infrastructure. Definitely a staple for our future inventory.

Standard SFP module, works as advertised. I haven't seen any heat issues even when the rack is running at full capacity. Solid engineering here.

We have been using these LINK-PP transceivers for over three months in a high-density deployment. Dealing with industrial-grade networking, we were worried about compatibility, but they handled the auto-negotiation protocols perfectly across our mix of brand-name switches. The optical budget is well within specs for our 8km runs, and the DOM reporting remains accurate. Highly recommended for network engineers tired of OEM price gouging.

Works fine on our Juniper gear. The module got a bit warm during heavy traffic, but it stayed within operating specs. Good value, but maybe keep an eye on your airflow in the rack.

Needed a cost-effective solution for a backup link and found these. They bridge the connection between our main core and the edge switch without any glitches.
