Reliable H3c Network Switch Optical Module SFP-Ge-Sx-mm850-D Network Management

H3C SFP-GE-SX-MM850-D 1000BASE-SX SFP Transceiver Module

The H3C SFP-GE-SX-MM850-D is a high-performance, hot-pluggable 1000BASE-SX SFP (Small Form-factor Pluggable) optical transceiver designed for short-range multi-mode fiber applications. Operating at an 850nm wavelength, this H3C SFP module delivers reliable Gigabit Ethernet connectivity for enterprise networks, data centers, and campus environments. It features an LC connector interface and supports a maximum transmission distance of up to 550 meters on 50/125μm multi-mode fiber, making it an ideal solution for high-speed data links.

Key Features

• Hot-pluggable SFP form factor for flexible deployment and easy maintenance
• Supports 1000Mbps data rate for Gigabit Ethernet applications
• 850nm wavelength optimized for multi-mode fiber systems
• LC duplex connector for secure and stable optical connection
• Low power consumption and high reliability for continuous operation
• Fully compliant with MSA (Multi-Source Agreement) standards for interoperability

Technology & Standards

The SFP-GE-SX-MM850-D complies with IEEE 802.3z 1000BASE-SX standards. It uses VCSEL (Vertical Cavity Surface Emitting Laser) technology for efficient optical transmission over multi-mode fiber. The module also supports Digital Diagnostic Monitoring (DDM) functions for real-time monitoring of temperature, voltage, TX bias, TX power, and RX power.

Working Principle

The transceiver converts electrical signals into optical signals using an 850nm VCSEL laser diode. The light is transmitted through multi-mode fiber to the receiving end, where a photodiode converts the optical signal back into an electrical signal. This bidirectional communication enables high-speed data transfer with low latency and high signal integrity.

Applications

The H3C SFP module is widely used in:

• Data center interconnects
• Enterprise backbone networks
• Campus network aggregation
• Gigabit Ethernet switches and routers
• Fiber Channel and SAN storage networks
