High-Performance Enterprise Optical Module SFP-Xg-Sx-mm850-D Gigabit Optical Module

H3C SFP-XG-SX-MM850-D 10G SFP+ SR Optical Transceiver

1. Product Overview

The H3C SFP-XG-SX-MM850-D is a high-performance, hot-pluggable SFP+ optical transceiver module designed for 10 Gigabit Ethernet applications. It operates at a wavelength of 850nm over multi-mode fiber (MMF), supporting a link length of up to 300 meters on OM3/OM4 cable. This module is fully compliant with the SFP+ MSA and IEEE 802.3ae 10GBASE-SR standards, ensuring seamless interoperability with a wide range of H3C networking equipment, including the LSQM2GT24PTSSC0 interface card. It is an ideal, cost-effective solution for high-speed data center interconnects, enterprise backbone networks, and storage area networks (SAN).

3. Technology & Standards

This SFP+ transceiver leverages VCSEL (Vertical-Cavity Surface-Emitting Laser) technology for highly reliable and efficient short-range optical transmission. It strictly adheres to critical industry standards including IEEE 802.3ae for 10GBASE-SR, the SFP+ Multi-Source Agreement (MSA), and the Digital Diagnostic Monitoring (DDM) specifications defined in SFF-8472, providing real-time monitoring of temperature, voltage, laser bias current, and transmitted/received optical power.

4. Working Principle

The electrical 10G data signal from the host switch's SFP+ port is received by the transceiver's driver IC. The IC drives an 850nm VCSEL laser diode, which converts the electrical signals into optical signals. These light pulses are transmitted through a multi-mode fiber via an LC connector. At the receiving end, a photodiode detector converts the incoming optical signals back into electrical data signals for the host system to process. The built-in DDM controller continuously monitors the module's operational parameters.

5. Application & Usage

The H3C SFP-XG-SX-MM850-D is deployed in diverse environments requiring high-bandwidth, short-reach connections:

• Data Centers: For top-of-rack (ToR) to end-of-row (EoR) switch connections and server aggregation.
• Enterprise Networks: Building backbone links and connecting high-performance workgroups.
• Storage Area Networks (SAN): Interconnecting switches and storage devices in Fibre Channel environments.
• High-Performance Computing (HPC): Providing low-latency, high-speed cluster interconnects.

9. Frequently Asked Questions (FAQ)

Q: Is this module compatible with my H3C S7500X switch?
A: Yes, the SFP-XG-SX-MM850-D is fully compatible with H3C S7500E and S7500X series switches, specifically on the 10GBASE-R-SFP+ ports of cards like the LSQM2GT24PTSSC0.

Q: What is the difference between this SR module and an LR module?
A: The SR (Short Range) module uses multi-mode fiber for distances up to 400m. The LR (Long Range) module uses single-mode fiber for distances up to 10km. Choose based on your distance requirements.

Q: Does this transceiver support DDM/DOM?
A: Yes, the SFP-XG-SX-MM850-D supports Digital Diagnostic Monitoring (DDM), allowing you to monitor real-time parameters like optical power and temperature.

Q: What type of fiber cable should I use?
A: For best performance and to achieve the full 300m distance, use OM3 or OM4 50/125μm laser-optimized multi-mode fiber patches with LC connectors.

10. Precautions

• Compatibility: Verify compatibility with your specific H3C switch model and software version (Requires H3C Comware Software Release 7150 or later).
• Fiber Type: Ensure the use of correct multi-mode fiber (OM3/OM4 for 300m). Using 62.5/125μm fiber will limit the distance to 33m.
• Handling: Avoid touching the LC connector ferrules. Always use clean fiber optic cleaning tools.
• Static & ESD: Handle with proper ESD precautions. Use an ESD wrist strap when installing or removing the module.
• Environment: Operate and store within the specified temperature and humidity ranges to ensure longevity and performance.
