D-Link DEM-436XT-BXU – 10GBASE-LR Bi-Directional Single-Mode 20km SFP+ Transceiver with Simplex LC Connector, TX 1270nm / RX 1330nm
Overview:
• The D-Link DEM-436XT-BXU is a 10GBASE-LR Bi-Directional SFP+ Transceiver designed for compatible switches, network adapters, and devices with SFP+ slots.
• It supports 10Gbps Ethernet over single-mode fiber, using WDM bi-directional transmission to send and receive data over a single fiber core.
• The module uses a Simplex LC connector and operates with TX 1270nm / RX 1330nm wavelength direction.
• It supports transmission distance up to 20km, making it suitable for long-distance 10G fiber uplinks, backbone links, and inter-building connections.
• The DEM-436XT-BXU is hot-pluggable, MSA compliant, and RoHS compliant, and should be paired with the matching opposite-end DEM-436XT-BXD module for correct wavelength operation.

Connect Gates Recommendation:
• Connect Gates recommends the D-Link DEM-436XT-BXU for projects that require 10Gbps single-fiber bi-directional connectivity up to 20km.
• It is ideal when only one single-mode fiber core is available and a 10G link is required.
• The module should be paired with DEM-436XT-BXD at the opposite end to match the TX/RX wavelengths correctly.
• For proper installation, Connect Gates recommends checking SFP+ slot compatibility, single-mode fiber availability, LC connector compatibility, required distance, and opposite-end module wavelength before deployment.
