D-Link DEM-311GT SFP/Mini-GBIC 1000Base-SX Multi-mode Fiber Transceiver

General Overview

The D-Link DEM-311GT is a small form-factor pluggable (SFP) transceiver module designed to extend the network connectivity capabilities of switches, routers, and other devices that support SFP interfaces. This multi-mode fiber transceiver is compliant with the 1000Base-SX standard, enabling high-speed data transmission over short distances.

Key Features

• Multi-Mode Fiber Compatibility:
  • Supports multi-mode fiber (MMF) connections, typically using OM1, OM2, OM3, or OM4 fiber cables.
• Data Rate:
  • Provides a data transmission rate of up to 1 Gbps (Gigabit Ethernet) over fiber.
• Wavelength:
  • Operates at a wavelength of 850 nm, which is ideal for multi-mode applications.
• Maximum Distance:
  • Capable of transmitting data over distances up to 550 meters (m) on OM2 fiber, 300 m on OM3 fiber, and 400 m on OM4 fiber, making it suitable for connecting devices within a building or across a campus.
• Form Factor:
  • SFP (Small Form-Factor Pluggable) design allows for hot-plugging, meaning it can be replaced without powering down the connected equipment.
• Connection Type:
  • Utilizes a standard LC connector for easy and reliable fiber optic connections.

Key Applications

• Network Expansion:
  • Ideal for expanding a network by enabling connections between switches, routers, or other network devices over fiber, supporting greater distances compared to copper connections.
• Data Centers:
  • Suitable for data center environments where high-speed connections and minimal latency are critical.
• Building Interconnectivity:
  • Perfect for linking buildings within a campus, as it provides high-speed data transfer while minimizing interference.

Compatibility

• The DEM-311GT is compatible with a wide range of D-Link switches and other devices that support SFP modules. It’s essential to check compatibility with specific devices before installation to ensure optimal performance.

Environmental Features

• Operating Temperature:
  • Designed to operate effectively within a temperature range typically between 0°C to 70°C (32°F to 158°F), making it suitable for most indoor environments.
• Low Power Consumption:
  • Engineered for high energy efficiency, contributing to lower operational costs in network setups.

Summary

The D-Link DEM-311GT SFP/Mini-GBIC 1000Base-SX Multi-mode Fiber Transceiver is an essential component for organizations looking to enhance their network infrastructure with reliable, high-speed fiber connections. Its versatile design, compatibility, and capability of delivering gigabit speeds over short distances make it an ideal choice for modern networking solutions.
