Tuân thủ tiêu chuẩn và khả năng tương thích
Tuân thủ tiêu chuẩn SFP MSA and SFF-8472 ensures interoperability with multi-vendor switches, routers and media converters. The datasheet confirms solid compatibility listings.

Global Service & Proven Track Record
The product listing shows real-world adoption and reviews across international customers.

4️⃣Use Case Scenarios

• Enterprise Network Uplink: Connect buildings or floor-level switches over 10 km single-mode fibre while supporting Gigabit connectivity.

• Data Centre Interconnect: Use as cost-effective SFP modules for intra-data-centre or campus connections.

• Metro/Carrier Edge: Suitable for access aggregation links where 10 km reach is sufficient and monitoring reliability is critical.

• Network Conversion or Upgrade: Ideal for migrating from older optics to modern DOM-capable modules while maintaining standard form factor and interface.

5️⃣ Compatibility

The LS-SM311G-10C gives you wide SFP compatibility. You can use it with switches and routers from Cisco, Juniper, Alcatel-Lucent, Avaya, IBM, Intel, DELL, and more. Here is a table that shows some compatible brands:

You can change sfp modules while your network is running. This hot-swappability helps you fix problems or upgrade your system without stopping your network. You keep your business online and avoid downtime.

You may see problems with compatibility in some networks. These problems can happen if you use third-party sfp modules with original equipment. Sometimes, the encoding does not match, and the module does not work. You can fix these problems by updating firmware and using the right coding.

Tip: Always check your switch or router manual for sfp compatibility before you buy a new module.

You can trust the LS-SM311G-10C SFP-1G-LX Module for strong performance, wide compatibility, and easy upgrades. You get a reliable 1g optical transceiver for your 1 gigabit ethernet network.

6️⃣ Deployment Considerations & Best Practices

• Ensure the host device supports +3.3 V SFP modules and the target data rate of 1.25 Gbps.

• Verify single-mode fibre quality and LC/UPC duplex connectors to maintain optical budgets and • margin for –23 dBm sensitivity.

• Use correct temperature variant if the operating environment is outside 0-70 °C (industrial version required for -40 °C to +85 °C).

• Monitor DOM readings regularly to detect potential signal degradation due to fibre bend, dust contamination or module ageing.

• Maintain proper inventory of spares, as consistent module reuse supports network stability and simplifies maintenance.
