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:
- 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.
- 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.
- 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.
- 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).
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
