Modern networks demand flexibility, speed, and interoperability. Whether you’re deploying campus LANs, data-center interconnects, or industrial automation, a reliable Optical Transceiver Module is essential.
The NS brand lineup of 1 Gbps Modules - comprising the SFP-1G-SX, SFP-1G-LX, and SFP-1G-TX - delivers multi-vendor compatibility, robust performance, and cost-effective scalability.
Engineered as true compatible transceiver modules, these generic SFPs work seamlessly in equipment from Cisco, Huawei, Juniper, Arista, and NS switch platforms - eliminating vendor-lock and simplifying spare-parts management.
Product Overview
All three models conform to MSA standards and support both 1 Gb/s and 1.25 Gb/s data rates, ensuring full interoperability with OEM and third-party devices. Key highlights:
- Broad Compatibility: Validated in Cisco, Huawei, Juniper, Arista, NS and other switches/routers.
- MSA Compliance: Plug-and-play in any SFP-enabled slot without special commands.
- Low Power: ≤ 1 W per module minimizes data-center cooling and power overhead.
- Hot-Plug Support: 20-pin SFP interface allows “live” module swaps.
By offering a truly generic module design, NS ensures you have a single SKU across diverse network fabrics.
Hardware Specifications
| Model | Media Type | Wavelength | Max Reach | Connector | Data Rate |
| SFP-1G-SX | Multi-Mode Fiber | 850 nm | 550 m @50/125 µm MMF | LC Duplex | 1.0 Gbps / 1.25 Gbps |
| SFP-1G-LX | Single-Mode Fiber | 1,310 nm | 10 km @9/125 µm SMF | LC Duplex | 1.0 Gbps / 1.25 Gbps |
| SFP-1G-TX | Copper (Twisted Pair) | N/A | 100 m @ Cat5e RJ45 | RJ45 Port | 1.0 Gbps (1.25 Gbps capable) |
- SFP-1G-SX: Ideal for short-distance connections in wiring closets or between adjacent buildings via MMF.
- SFP-1G-LX: Perfect for campus backbones and metro links over SMF.
- SFP-1G-TX: Provides flexible copper uplinks using an integrated RJ45 Port, avoiding fiber installation costs.
Each module draws < 1 W and operates over 0 °C–70 °C, making them suitable for standard and harsh environments.
Compatibility & Interoperability
A true compatible transceiver module must “just work” in any vendor’s equipment. NS brand SFP-1G series passes these tests:
- Cisco Catalyst & Nexus
- Huawei Switches & Routers
- Juniper EX/QFX & MX Series
- Arista 7000 & 7200 Series
- NS Brand Switches & Routers
Our modules ship with pre-programmed EEPROM that emulates OEM signatures, eliminating “unsupported transceiver” errors. Customers report seamless operation in both optical and copper SFP slots without CLI tweaks or hazardous register hacks.
NS Brand vs. OEM vs. Other Third-Party
| Feature | NS Brand Module | OEM Module (e.g., Cisco) | Other Third-Party Module |
| Cross-Vendor Compatible | Yes; Cisco, Huawei, Juniper, Arista, NS | No; locked to vendor | Partial; often Cisco-only |
| Data-Rate Support | 1 Gbps & 1.25 Gbps | 1 Gbps | 1 Gbps |
| Warranty | 3 years | 1 year | Varies |
| DDM/DOM Support | Full per MSA | Full per MSA | Limited |
| Price Point | – 30% vs. OEM | Premium | – 10% vs. OEM |
| Availability | Stocked globally | Varies by region | Spotty |
| Hot-Swap Support | Yes | Yes | Yes |
NS modules not only match OEM quality in DDM accuracy and MSA compliance but also undercut OEM pricing—delivering true generic module flexibility without compromise.
Deployment Scenarios & Use Cases

Management
Installation & Diagnostics
Despite being generic modules, NS transceivers support all standard SFP diagnostics:
- DDM/DOM: Monitor Tx/Rx optical power, temperature, voltage, bias current.
- Hot-Plug: No reboot required—modules can be swapped live with no traffic interruption.
- LED Indicators: On NS switches, per-port LEDs reflect link speed and activity when using any SFP.
Quick-start CLI Snippet (Cisco IOS example):

FAQ
-
Do these modules really work in any vendor’s switch?
Yes. NS runs each SFP through lab tests on Cisco, Huawei, Juniper, Arista, and NS gear to guarantee plug-and-play operation. -
What’s the benefit of 1.25 Gbps rate support?
It ensures seamless operation in newer 2.5G/5G-capable switches that autonegotiate beyond 1 Gbps. -
Can I mix SX, LX, and TX modules in the same chassis?
Absolutely. MSA compliance and DDM support let you install all three types without manual overrides. -
How do I verify optical power and link status?
Use your switch’s “show interfaces transceiver details” command or an external fiber tester. -
Is there a temperature-hardened version?
Yes—industrial-grade modules rated –40 °C to +85 °C are available on request. -
Can I return if compatibility issues arise?
NS offers a 30-day money-back guarantee and next-business-day RMA replacements.
