Can I use two SFP-XG-LX-SM1270-BIDI modules to connect a point-to-point link?

No. This BiDi module transmits at 1270nm and receives at 1330nm. You must pair it with a complementary module at the other end (1330nm-TX/1270nm-RX) to establish a link.

What type of fiber optic patch cable does this transceiver require?

It requires a Single-Mode Fiber (SMF) patch cable terminated with a simplex LC connector.

What is the maximum transmission distance supported by this module?

This optical transceiver reliably supports data transmission distances up to 10km over standard single-mode fiber.

Does this transceiver support real-time health monitoring?

Yes. It features internal Digital Diagnostic Monitoring (DDM/DOM) via an I2C interface to track temperature, voltage, bias current, and optical power.

Hey guys, will this module work smoothly with my mixed rack of Cisco Nexus and Ubiquiti EdgeSwitches? Need to make sure before buying.

Absolutely! This 10G SFP+ BiDi module is fully SFP+ MSA compliant and widely tested for seamless OEM compatibility with Cisco, Ubiquiti, Juniper, and other major networking brands. Just plug and play!

We're planning a massive campus upgrade and need about 200 of these 1270/1330nm transceivers. Any chance we can get a bulk discount?

Yes, we definitely offer volume pricing for enterprise batch deployments! Please reach out to our B2B sales team directly, and we'll set you up with a custom discounted quote to help manage your procurement budget.

I see the operating temperature is 0 to 70°C. We have some outdoor network cabinets that get brutal in the winter. Do you carry an industrial version?

Good catch! The LS-BL273310-10C is our commercial-grade version designed for indoor or climate-controlled environments. For harsh outdoor conditions, you'll want to grab our industrial version (LS-BL273310-10I), which is engineered to safely operate from -40°C to 85°C.

We are doing some cell tower backhaul upgrades. Does this transceiver natively support telecom protocols like CPRI?

You bet! It fully supports both CPRI and eCPRI protocols at bit rates up to 10.7Gbps, making it an incredibly stable and cost-effective choice for 4G/5G base station front-haul and backhaul networks.

Bought 50 units for outdoor cabinets. Even at near 70°C case temp during stress tests, the 10G SFP+ DOM data stayed stable. Truly an impressive 10Gbps simplex LC transceiver.
