D-Link DEM-330R – 1000BASE-BX-U Single-Mode 10km Gigabit SFP Transceiver with Simplex LC Connector, TX 1310nm / RX 1550nm & Hot-Swappable Design
Overview:
• The D-Link DEM-330R is a Bidirectional Gigabit SFP Fiber Transceiver designed for installation in compatible SFP slots of network switches and fiber network devices.
• It supports Gigabit Ethernet transmission over single-mode fiber using a single fiber strand for both transmitting and receiving data.
• The module uses bidirectional wavelength operation, transmitting at 1310nm and receiving at 1550nm.
• The DEM-330R supports fiber cable distance up to 10km and is designed to work as the matching pair with DEM-330T at the opposite end of the fiber link.
• It features a Simplex LC connector, standard SFP metal housing, 3.3V power supply, and hot-swappable installation, making it suitable for long-distance Gigabit fiber network applications.

Connect Gates Recommendation:
• Connect Gates recommends the D-Link DEM-330R for projects that require Gigabit single-fiber bidirectional connectivity up to 10km.
• It is suitable when only one fiber core is available and a Gigabit fiber link is required.
• The DEM-330R should be paired with DEM-330T to complete the TX/RX wavelength match correctly.
• For proper installation, Connect Gates recommends checking switch SFP compatibility, single-mode fiber availability, LC connector compatibility, fiber distance, and the matching opposite-end transceiver wavelength before deployment.
