3. Technology & Standards

The SFP-XG-LX-SM1310-D module leverages advanced 1310nm Distributed Feedback (DFB) laser technology to achieve high-speed, long-distance data transmission. It is designed to meet stringent industry standards, ensuring reliability and compatibility.

• Compliant Standards: IEEE 802.3ae 10GBASE-LR, SFF-8472 (DDM/DOM), SFF-8431, SFF-8432
• Protocols: 10 Gigabit Ethernet
• Data Encoding: 64B/66B

4. Working Principle

The transceiver converts electrical signals from the host switch into optical signals using an integrated 1310nm DFB laser. These light pulses are transmitted through a single-mode optical fiber to a receiving transceiver. The receiver side of the module uses a PIN photodiode to convert the incoming optical signals back into electrical signals for the switch to process. The integrated Digital Diagnostic Monitoring (DDM) circuit provides real-time access to operational parameters such as optical output power, received power, laser bias current, and transceiver temperature, enabling proactive network management.

5. Application & Usage

The H3C SFP-XG-LX-SM1310-D is ideal for a variety of applications that require reliable 10G connectivity over medium to long distances.

• Data Center Interconnects: Connecting switches across different rooms or buildings.
• Enterprise Backbone Networks: Aggregating traffic between wiring closets and the main network core.
• Service Provider Access & Metro Networks: Providing high-bandwidth links for network aggregation.
• Storage Area Networks (SAN): Supporting high-speed storage protocols like Fibre Channel over Ethernet (FCoE).
• It is commonly deployed in compatible H3C switches such as the S7500E and S7500X series.

9. Frequently Asked Questions (FAQ)

Q1: Is this SFP+ module compatible with my H3C S7500X switch?
A1: Yes, the SFP-XG-LX-SM1310-D is designed to be fully compatible with H3C S7500X and S7500E series switches, as listed in the official documentation.

Q2: What is the difference between LX and SR transceivers?
A2: LX modules (like this 1310nm variant) are for long-reach transmission over single-mode fiber (up to 10km). SR modules (850nm) are for short-reach over multi-mode fiber (typically up to 300m).

Q3: Does this module support DDM/DOM?
A3: Yes, the SFP-XG-LX-SM1310-D supports Digital Diagnostic Monitoring, allowing you to monitor parameters like temperature, voltage, and optical power.

Q4: What type of fiber cable should I use with this transceiver?
A4: You must use a 9/125 µm single-mode duplex LC fiber patch cable for optimal performance over the advertised distance.

10. Precautions

• Ensure the module is compatible with your specific H3C switch model and software version.
• Always use an LC connector single-mode fiber (SMF) patch cable with a 9/125µm core.
• Avoid bending the fiber cable beyond its minimum bend radius to prevent signal loss.
• Do not remove the protective dust caps from the optical ports until you are ready to connect the fiber cable.
• Handle the module carefully by its edges; avoid touching the gold-plated electrical contacts or the optical port interfaces.
• Install the module in a well-ventilated environment within the specified operating temperature range.
