Ruijie GE‑SFP‑LX20‑SM1310‑BIDI is a 1G BiDi SFP transceiver for single‑mode fibre links up to 20 km. It transmits at 1310 nm and receives at 1550 nm; use with the complementary Tx1550/Rx1310 module at the remote end. The module is hot‑pluggable, supports IEEE 1000BASE‑LX and provides digital diagnostics (DDM/DOM).

• Single‑fibre BiDi: saves one fibre strand using a simplex LC (BiDi) connector pair.
• Data rate: 1.25 Gbps (1000BASE‑LX compatible).
• Link reach: up to 20 km over single‑mode fibre (SMF).
• Monitoring: Digital Diagnostics Monitoring (DDM/DOM) supported for real‑time optical and electrical parameters.
• Power & form factor: SFP MSA form factor, hot‑pluggable, ≤ 1.5 W power consumption.

Compliance & safety: RoHS compliant and Class 1 laser safety. Typical operating temperature (commercial grade) 0 °C to 70 °C. Ensure you pair this module with the complementary GE‑SFP‑LX20‑SM1550‑BIDI (Tx/Rx reversed) on the remote device for correct bi‑directional operation.

Installation note: verify SFP compatibility with your switch/router vendor — while SFP MSA form factor is standard, some vendors require validated/approved optics. For full technical details and datasheet references, consult the Ruijie product page and datasheet.
