Ruijie GE-SFP-LH40-SM1550-BIDI is a 1.25 Gbps SFP (mini-GBIC) optical transceiver for single-mode fibre. It provides single-fibre bi-directional (BIDI) operation with TX at 1550 nm and RX at 1310 nm, supporting point-to-point links up to 40 km. The module is hot-pluggable, supports Digital Diagnostic Monitoring (DDM/DOM) and conforms to IEEE 802.3 and SFP/SFF MSA standards.

• 1.25 Gbps (1000BASE-X / 1000BASE-LX/LH) throughput
• BIDI single-fibre operation: TX 1550 nm / RX 1310 nm, LC simplex connector
• Reach up to 40 km over single-mode fibre (SMF), UPC finish
• Supports DDM/DOM for real-time diagnostics
• Low power consumption (≤ 1.5 W) and hot-pluggable SFP form factor
• Meets IEEE 802.3, SFF SFP MSA; RoHS and Class 1 laser safety compliant

Use cases: Enterprise and campus single-mode links, metro interconnects, data centre uplinks where single-fibre BIDI modules reduce fibre cabling. Suitable for network engineers and installers requiring OEM-grade Ruijie modules.

Safety & compliance: Observe standard fibre handling and laser safety practices. Module is Class 1 laser compliant; installation should follow vendor installation guide and local regulations (CE/UKCA where applicable). If unsure, use a qualified network installer.
