D-Link DEM-330T – 1000BASE-BX-D Single-Mode 10km Gigabit SFP Transceiver with Simplex LC Connector, TX 1550nm / RX 1310nm & Hot-Swappable Design
Overview:
• The D-Link DEM-330T is a Bidirectional Gigabit SFP Fiber Transceiver designed for insertion into compatible SFP slots of network devices.
• It supports Gigabit fiber transmission over single-mode fiber using a single fiber strand for both transmission and reception.
• The module supports bidirectional operation using separate transmit and receive wavelengths.
• The DEM-330T supports fiber cable distance up to 10km and should be used with the matching opposite wavelength module for correct link operation.
• It features a Simplex LC connector, standard SFP package, 3.3V power supply, hot-swappable installation, and a durable metal enclosure.

Connect Gates Recommendation:
• Connect Gates recommends the D-Link DEM-330T for projects that require Gigabit single-fiber bidirectional connectivity up to 10km.
• It is suitable when only one fiber core is available and Gigabit transmission is required.
• The Simplex LC connector, single-mode fiber support, hot-swappable design, and durable metal enclosure make it practical for professional network backbone installations.
• For proper installation, Connect Gates recommends checking switch SFP compatibility, single-mode fiber availability, LC connector compatibility, required distance, and the matching opposite-end transceiver wavelength before deployment.
