FAQ for SFP-10G-LR
Q1: What makes SFP‑10G‑LR different from DS‑SFP‑FC10G‑LW transceivers?
A1: The core difference lies in supported transmission protocols. SFP‑10G‑LR is engineered for regular 10G Ethernet network deployments. DS‑SFP‑FC10G‑LW is dedicated to Fibre Channel storage networks and runs at the unique 10.518 Gbps Fibre Channel line rate.These two modules cannot be swapped for use on non‑unified switch ports.Bulk and long-term supply available for these two compatible modules from HYTOPTODEVICE
Q2: What does the suffix “LW” mean in the DS‑SFP‑FC10G‑LW part number?
A2: LW is short for Long‑Wave or Long‑Wavelength in Fibre Channel naming rules. Long‑Wave optics are designed for single‑mode fiber links at 1310nm, supporting transmission up to 10 kilometers.In contrast, SW (Short‑Wave) refers to multi‑mode fiber transceivers used for short‑distance connections.
Q3: Does installing a third‑party compatible DS‑SFP‑FC10G‑LW transceiver void the warranty of my Cisco MDS switch?
A3: No, it will not. Under relevant consumer protection regulations, hardware vendors are not allowed to invalidate device warranties only because users select reliable third‑party compatible optical transceivers. Our modules match OEM‑level stability while offering a more cost‑effective solution.
Q4: How can I confirm your compatible DS‑SFP‑FC10G‑LW works well with my Cisco MDS switch?
A4: Compatibility is fully guaranteed.
Every batch of our transceivers is tested on real Cisco MDS hardware before delivery.
We can also provide real‑world test videos showing stable module recognition and normal data transmission in live MDS switch environments if you require.
Q5: Is DOM monitoring available for this module on Cisco MDS supervisor modules?
A5: Yes, our compatible DS‑SFP‑FC10G‑LW supports full Digital Optical Monitoring (DOM).
You can check key parameters such as laser working status, transmit and receive optical power, and module temperature through NX‑OS commands like show interface transceiver details.
Q6: Which fiber cable is suitable for DS‑SFP‑FC10G‑LW connection?
A6: A duplex LC‑to‑LC single‑mode fiber patch cord is the basic requirement. For stable signal transmission over the full 10‑km reach, OS2 grade 9/125µm single‑mode fiber is strongly recommended.
Q7: Can DS‑SFP‑FC10G‑LW operate at lower Fibre Channel speeds such as 8G, 4G or 2G?
A7: No. DS‑SFP‑FC10G‑LW is a fixed‑rate 10G Fibre Channel transceiver. It cannot be downgraded to support 8G, 4G or 2G Fibre Channel speeds.
