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.
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.

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.
