Compatibility and Supported Devices
The HYTOPTODEVICE GP-SFP-10GBX-D-40 compatible Dell is rigorously tested to ensure 100% compatibility with Dell EMC Networking platforms:
Dell S-Series (Data Center): S4048-ON, S4148F-ON, S5248F-ON, and S6000 series switches.
Dell N-Series (Managed Campus): N4032, N4064, and N3000 series with 10G SFP+ uplinks.
Dell Z-Series (Core Aggregation): Z9100-ON and Z9264F-ON high-performance switches.
Dell PowerConnect: Legacy support for 8100 series (e.g., 8132, 8164).
Multi-Site Data Center Interconnect (DCI): Linking separate data center facilities up to 40km apart using a single fiber core to reduce monthly leasing costs.
Metropolitan Area Network (MAN) Expansion: Providing a stable 10G SFP+ 40km BiDi backhaul for regional offices and suburban business parks.
Campus Core Backbone Extension: Bridging university or hospital campus locations where distances exceed the standard 10km limit.
ISP Metro Aggregation: Delivering high-speed 10G services to residential or commercial hubs via high-reliability 40km single-strand fiber links.

Q1: What is the matching partner for the Dell GP-SFP-10GBX-D-40? A: This Downstream (D) BiDi transceiver must be paired with the GP-SFP-10GBX-U-40 (Upstream). The D-40 transmits at 1330nm/receives at 1270nm, while the U-40 transmits at 1270nm/receives at 1330nm.
Q2: Does Dell OS10 require any special configuration to use this module? A: No. HYTOPTODEVICE modules are pre-programmed with Dell-specific signatures. They provide full Dell Networking OS10 optical interoperability, meaning they are recognized as native hardware without needing "allow-unsupported" commands.
Q3: Can I monitor the optical power budget in real-time? A: Yes. The GP-SFP-10GBX-D-40 module supports full Digital Optical Monitoring (DOM). Use the Dell CLI command show interfaces transceiver to monitor TX/RX power levels, which is critical for long-distance 40km troubleshooting.
Q4: Is an attenuator required for short-distance testing? A: Yes. Since this is a 40km extra long-reach laser, the signal is very strong. For fiber runs under 10km, we recommend a 5dB optical attenuator to prevent damaging the sensitive optical receiver.
Q5: How does this help with fiber-constrained environments? A: It enables cost-effective single-strand fiber migration. By using BiDi technology, you can run a full 10G link on one fiber strand, effectively doubling your existing cable capacity instantly.
Q6: What is the operating temperature range for this 40km module? A: This module is rated for the commercial temperature range (0°C to 70°C). For unconditioned outdoor cabinets, we recommend our Industrial Temperature version:HYTOPTODEVICE industrial temperature transceivers.
Q7: Will using this module void my Dell warranty? A: No. Using high-quality compatible transceivers is protected by law and does not void your Dell hardware warranty.
Q8: Does it support 10G Ethernet and OTN? A: It is optimized for 10G Ethernet (10.31 Gbps). For OTN (10.7G/11.1G) requirements, HYTOPTODEVICE supports it.
Q9: Is the GP-SFP-10GBX-D-40 hot-swappable? A: Absolutely. It is a hot-pluggable SFP+ BiDi module, Hot Pluggable SFP+ MSA compliant, allowing you to insert or remove it from the switch while it is powered on.
Q10: What is the lead time for HYTOPTODEVICE Dell compatibles? A: We usually maintain local stock for 24-hour shipping. All Dell-compatible modules are backed by a 3-year replacement warranty.
