Dlink DEM-311GT SFP 1000Base-SX Multi-mode Fibre

The D-Link DEM-311GT is a Gigabit Ethernet Mini-GBIC (Gigabit Interface Converter) module designed to provide high-speed network connectivity for compatible D-Link networking equipment. Here’s a description of this specific network module:

1. Module Type: The DEM-311GT is a Mini-GBIC module, which is also known as a Small Form-Factor Pluggable (SFP) module. These modules are hot-swappable, meaning they can be inserted or removed from compatible devices without powering down the equipment.
2. Gigabit Ethernet: This module supports Gigabit Ethernet (1000BASE-SX) connectivity. It’s capable of providing network speeds of up to 1 gigabit per second (1 Gbps), making it suitable for high-speed data transfer in Ethernet networks.
3. 1000BASE-SX: The “1000BASE-SX” designation indicates the specific Gigabit Ethernet standard this module adheres to. 1000BASE-SX is a multimode fiber optic standard commonly used for short-distance network connections within data centers, campus networks, and similar environments.
4. Fiber Optic Connectivity: The module uses fiber optic technology for data transmission. Fiber optics are known for their high data transmission speeds and immunity to electromagnetic interference (EMI).
5. Compatibility: The DEM-311GT module is designed to be compatible with D-Link networking equipment that supports SFP modules. This includes various D-Link switches and routers equipped with SFP slots.
6. LC Connector: The module typically features LC (Lucent Connector) connectors, which are common in fiber optic connections. LC connectors are known for their compact size and ease of use.
7. Distance and Range: The module’s range and distance capabilities depend on the specific fiber optic cable used and the network’s configuration. In general, 1000BASE-SX is suitable for relatively short-distance connections within the same building or data center.
8. Hot-Swappable: Being hot-swappable means you can install or remove the module while the connected equipment is powered on, allowing for easier maintenance and network adjustments without downtime.
9. Network Expansion: These modules are often used for network expansion or when longer cable distances are required beyond what traditional copper Ethernet cables can support.
10. Network Reliability: Fiber optic connections, such as those facilitated by this module, are known for their reliability and ability to transmit data over longer distances without signal degradation.

The D-Link DEM-311GT Mini-GBIC module is a versatile and essential component for network administrators looking to expand their network infrastructure or upgrade existing equipment to support Gigabit Ethernet over fiber optic connections. For specific compatibility and installation instructions, it’s recommended to refer to the product’s documentation or the manufacturer’s website.
