Compatibility and Supported Device
The HYTOPTODEVICE DEM-436XT-BXD 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 pairing requirement for the D-Link DEM-436XT-BXD? A: The DEM-436XT-BXD (Downstream) transmits at 1330nm and receives at 1270nm. It must be paired with the DEM-436XT-BXU (Upstream) module, which transmits at 1270nm and receives at 1330nm.
Q2: Will this module work with D-Link switches without software warnings? A: Yes. HYTOPTODEVICE modules are pre-programmed with D-Link specific EEPROM signatures. Your switch will recognize it as a native DEM-436XT-BXD, ensuring plug-and-play performance without error messages.
Q3: Does the DEM-436XT-BXD support real-time monitoring (DOM)? A: Absolutely. It supports full Digital Optical Monitoring (DOM). You can view real-time metrics such as TX/RX power, temperature, and voltage via the D-Link Web GUI or CLI.
Q4: Can I use this 20km module for a shorter link of 5km? A: Yes. The high-quality laser features a wide dynamic range, allowing it to function perfectly on shorter distances without saturating the optical receiver.
Q5: Is it hot-swappable in a running DXS-3400 switch? A: Yes. The module is hot-pluggable, meaning you can insert or remove the transceiver while the switch is powered on without disrupting other active ports.
