Who is this for?
Network engineers and procurement teams building 10 GbE links in data centers and campus networks who want broad multi-vendor compatibility and better TCO without sacrificing standards-based performance.
TL;DR (pick fast):
- Short runs inside/adjacent racks → NS-SFP-10G-SR (MMF 850 nm, OM3 300 m / OM4 400 m) — great value for TOR/leaf server uplinks.
- Campus/backbone up to 10 km → NS-SFP-10G-LR (SMF 1310 nm, 10 km) — stable long-haul with DOM/DDM.
- Re-use copper or temporary links → NS-SFP-10G-TX (RJ-45, 10 G ≤ 30 m; 1 G ≤ 100 m, ~2.5 W) — zero new fiber.

10GBASE-T (Copper RJ-45)
| Brand / Model | Medium | Reach | Power | Compatibility | Value Note |
| NS-SFP-10G-TX | Copper | 10 G ≤ 30 m; 1 G ≤ 100 m | ≈2.5 W | Broad multi-vendor | Fiber-free upgrades; lowest disruption. |
| Cisco SFP-10G-T-X | Copper | 10 G ≤ 30 m; 1 G ≤ 100 m | ≈2.5 W | Native in Cisco ecosystem | OEM premium; PoE heat budgets to watch. |
| Third-party (e.g., FS/10Gtek TX) | Copper | Equivalent class | ~2.5–3 W class | Multi-vendor | Budget-friendly where heat isn’t limiting. |
Takeaway: Across SR/LR/TX, standards and headline specs are equivalent among reputable vendors; paying OEM premiums mostly buys you single-vendor branding. NS modules pair broad compatibility with clear pricing and fast fulfillment, lowering the total cost of ownership (TCO).
Why we recommend NS-SFP-10G-SR / LR / TX？
-
Covers 90% of 10 GbE use cases with a minimal, predictable kit.
SR for MMF short-reach, LR for SMF 10 km, TX when you must keep copper (e.g., interim builds, brownfield). -
Operational visibility with DOM/DDM (optical).
SR/LR include digital diagnostics so you can catch attenuation and temperature drift early. -
Multi-vendor coding & pre-ship checks.
We can align EEPROM IDs for Cisco/Juniper/Arista/Huawei/Ruijie and test on your OS versions before dispatch—plug-and-go on day one. -
Honest power profiles.
Copper runs hotter (~2.5 W). We’ll confirm airflow/PSU headroom in dense chassis; optics are ~≤1–1.3 W. -
Price transparency + after-sales cover.
Live pricing on SR/LR/TX, with NS warranty and return terms clearly documented.
Buying Guide
Step 1 — Medium & distance
- SR: MMF 850 nm, OM3 300 m / OM4 400 m. Use for rack-row links, TOR/leaf/server.
- LR: SMF 1310 nm, 10 km. Use for campus/inter-building or long horizontal backbone.
- TX: RJ-45 copper, 10 G ≤ 30 m (Cat6a/7), 1 G ≤ 100 m (Cat5e/6). Use for brownfield/temporary links.
Step 2 — Connectors & patching
LC duplex for SR/LR; RJ-45 for TX. Check panel polarity, jumpers, and loss budgets.
Step 3 — DOM/monitoring
Enable DOM on SR/LR to watch TX/RX power and module temperature; set alerts around your loss budget.
Step 4 — Compatibility & coding
Most modern switches accept third-party modules, but ID checks or feature gating may apply; we’ll match vendor coding and validate on your platform/OS (e.g., Cisco IOS-XE/NX-OS, Junos, EOS, VRP).
Step 5 — Power & thermal
Budget ~2.5 W per copper TX and ensure front-to-back airflow in dense blades. Optics run cooler.

What our Customers Said?
FAQs
Q1: How do I choose between SR, LR and TX?
A: Start with medium & distance: SR (MMF 850 nm, OM3 300 m / OM4 400 m), LR (SMF 1310 nm, 10 km), TX (RJ-45, 10 G ≤ 30 m; 1 G ≤ 100 m). Then confirm patch panels and power budgets.
Q2: Will NS modules work on my Cisco/Juniper/Arista/Huawei/Ruijie gear?
A: Yes, our optics adhere to MSA/IEEE. We can apply vendor coding and verify on your exact platform/OS so they behave like native parts.
Q3: Why does 10GBASE-T stop at ~30 m for 10 G?
A: That’s the design envelope for 10G over copper in SFP+ form factor given insertion loss and PHY power/thermal constraints. At 1 G, runs to 100 m are supported.
Q4: Do SR/LR support DOM/DDM?
A: Yes, enable it to watch TX/RX power and module temperature for faster troubleshooting.
Q5: What warranty and returns do I get?
A: NS cover: 3-year warranty, 30-day quality-issue free return, and 1-year free parts & repair; fast global shipping via DHL/UPS.
