Can I use the GP-SFP-10GBX-U-40 module on a standard duplex LC fiber patch cord?

No, this is a BiDi (Bidirectional) transceiver designed exclusively for single-fiber links. It requires a single-mode simplex LC patch cord to operate.

What is the maximum transmission distance supported by this SFP+ transceiver?

The module supports long-reach single-mode fiber (SMF) data transmissions up to a maximum distance of 40km.

Do I need to pair this module with an identical GP-SFP-10GBX-U-40 at the other end?

No, pair it with a 1330nm-TX/1270nm-RX module to match its 1270nm-TX/1330nm-RX wavelengths.

What parameters can I monitor using the built-in DDM function?

It tracks real-time temperature, supply voltage, laser bias current, and transceiver input/output power.

We need to deploy these in bulk for our new data center. Do you offer wholesale discounts if we purchase 500+ units? Also, are they 100% compatible with Cisco Nexus switches?

Yes! We offer tiered pricing for batch deployments. For an order of 500+ units, please reach out to our sales team for a custom wholesale quote. As for compatibility, the LS-BL273310-40C is fully SFP+ MSA compliant and has been rigorously tested to work seamlessly with Cisco Nexus series and other major brands.

Our outdoor cabinets get pretty hot in the summer. Is this 0-70°C commercial version okay, or do you have an industrial wide-temp version? Also, just to confirm, it uses a simplex LC SMF patch cable, right?

For outdoor cabinets without climate control, we highly recommend our industrial wide-temp version (LS-BL273310-40I) which operates flawlessly from -40°C to 85°C. And you are correct—this is a BiDi module, so it only requires a single-mode fiber (SMF) paired with a simplex LC connector, reducing your fiber cabling footprint.

I'm planning to use these for a remote 5G base station backhaul over 35km. Does this transceiver support CPRI/eCPRI protocols? Do I need to buy a specific model for the other end?

Absolutely, this transceiver fully supports CPRI and eCPRI protocols, making it ideal for base station backhauls. Since this is a BiDi module transmitting at 1270nm and receiving at 1330nm, you must pair it with the complementary module (1330nm-TX/1270nm-RX) at the other end of your 35km link.
