Product Detail:
D-Link DEM-436XT-BXU Compatible 10GBASE-BX20-U SFP+ BiDi 1270nm-TX/1330nm-RX 20km DOM Transceiver Module
   The HYTOPTODEVICE D-Link DEM-436XT-BXU compatible module is a carrier-grade 10G SFP+ BiDi transceiver designed for single-mode fiber bandwidth optimization over medium distances. Functioning as the Upstream (U) component, this module transmits at 1270nm-TX and receives at 1330nm-RX, enabling a robust 10Gbps connection over just one strand of fiber. This bi-directional SFP+ 20km solution is ideal for organizations seeking a cost-effective fiber migration, allowing for a 50% reduction in cabling infrastructure requirements. Fully compliant with SFP+ MSA SFF-8431 and pre-programmed for D-Link switch optical compatibility, it provides seamless "Plug-and-Play" integration with DGS and DXS series switches. With integrated Digital Optical Monitoring (DOM) and a 20km reach, it ensures high-performance connectivity for enterprise backbones, metropolitan networks, and campus-wide aggregations.

Compatibility and Supported Device

The HYTOPTODEVICE DEM-436XT-BXU is rigorously tested to ensure 100% compatibility with D-Link Networking platforms:

  • D-Link DXS Series (10G Aggregation): DXS-3400, DXS-3600, and DXS-1210 series switches.

  • D-Link DGS Series (Managed Gigabit): DGS-3630, DGS-3420, and DGS-1510 series with 10G SFP+ uplinks.

  • D-Link D-Stack Series: Supporting high-bandwidth stacking over fiber for distributed campus environments.

  • D-Link Core Chassis: Suitable for use in 10G line cards for modular chassis systems.

Primary Usage Scenarios
  • Campus Fiber Optimization: Connecting D-Link DXS switches between different campus buildings using a single fiber core, reducing infrastructure overhead.

  • Mid-Range Data Center Interconnect (DCI): Establishing high-speed low-latency 10G BiDi links for server replication over distances up to 20km.

  • ISP Metro Aggregation: Providing stable 10G SFP+ 20km BiDi backhaul for residential high-speed internet aggregation points.

  • Enterprise Core-to-Distribution: Bridging distribution layers to the core switch where existing fiber strands are at maximum capacity.

FAQ for D-Link DEM-436XT-BXU Compatible 10GBASE-BX SFP+BiDi Transceivers

Q1: What is the required matching module for the DEM-436XT-BXU? A: The DEM-436XT-BXU (Upstream) must be paired with the DEM-436XT-BXD (Downstream). The BXU transmits at 1270nm and receives at 1330nm, while the BXD does the exact opposite.

Q2: Will using HYTOPTODEVICE modules show as "unsupported" in D-Link switches? A: No. Our modules are specifically coded with D-Link signatures. Your switch will recognize the module as a native DEM-436XT-BXU, providing full functionality without software overrides.

Q3: Can I monitor the optical power and temperature of this module? A: Yes. The module supports Digital Optical Monitoring (DOM). You can check the real-time TX/RX power and health status via the D-Link CLI or the Web Management Interface.

Q4: Is this 20km module suitable for short fiber runs? A: Yes. The high-quality laser has a wide dynamic range, meaning it can function on shorter links (e.g., 2km) without saturating the receiver.

Q5: Is it hot-swappable? A: Absolutely. It is a hot-pluggable SFP+ module, so you can install or replace it while the D-Link switch is running without interrupting network uptime.
