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

D-Link’s new line of Gigabit Interface Converters (GBICs) and Small Form-Factor Pluggables (SFPs) transceivers represent an industry leading combination of performance and affordability. D-Link’s new Gigabit transceivers are available in two form-factors: standard (GBIC) or (SFP)/mini-GBIC.

The DEM-311GT is a high performance 850nm multimode SFP/mini-GBIC transceiver. Supporting full duplex, Gigabit speeds on multimode fiber for distances of up to 220m/550m on 62.5µm/50µm fiber respectively. The unit features a metal housing to reduce EMI and to increase durability.

Consequently, here is a detailed description of the DEM-311GT:

Key Features and Specifications:

• Type: SFP (Small Form-factor Pluggable) transceiver, also known as a mini-GBIC.
• Speed: Supports full-duplex Gigabit speeds (1000 Mbps).
• Standard: Specifically, it is compliant with the IEEE 802.3z 1000BASE-SX standard, which is designed for multimode fiber.
• Wavelength: Operates at a wavelength of 850 nm, which is typical for multimode fiber optics.
• Connector: Uses a duplex LC connector, which is to say, a standard interface for fiber-optic cables.
• Fiber Media: Designed for use with multimode fiber (MMF). Furthermore, the maximum distance it can cover depends on the type of multimode fiber used:
  • Up to 550 meters on 50/125 µm multimode fiber.
  • Up to 220 meters on 62.5/125 µm multimode fiber.
• Hot-pluggable: This means the module can be installed or removed while the network device is powered on, thereby allowing for easy maintenance and expansion without interrupting the network.
• Durability: The unit features a metal housing, so as to reduce electromagnetic interference (EMI) and increase its overall durability.
• Compatibility: It is built to be compatible with D-Link switches and as well as other devices that have SFP slots.
• Power: Operates on a single +3.3V power supply.
