Overview

• Ruijie NIS‑GE‑SFP‑20KM‑SM1550‑BIDI is a 1.25 Gbps SFP (1000BASE‑LX class) single‑fibre BiDi optical transceiver. It operates TX 1550 nm / RX 1310 nm over a simplex LC connector for single‑mode fibre up to 20 km.
• Hot‑pluggable, supports Digital Diagnostic Monitoring (DDM/DOM) and complies with SFP MSA and common IEEE optical standards.

Key benefits

• Saves fibre ports and cabling — single‑fiber BiDi operation using LC simplex.
• DDM/DOM for real‑time optical diagnostics and simpler troubleshooting.
• Low power (≤ 1.5 W) and hot‑swappable for minimal downtime.
• Available in industrial (NIS) variants for extended temperature operation — confirm SKU with supplier if required.

Use cases

• Edge switches, access layer, and media conversion where single‑fibre runs are needed.
• Industrial networks where extended temperature operation or additional warranty is required (confirm industrial SKU).

Compliance & safety

• Meets SFP MSA, IEEE 802.3z and common SFF specifications; RoHS and Class 1 laser safety compliant.
• Ensure the SKU you receive matches the temperature rating and warranty you require. Installation and replacement should be performed by qualified personnel following supplier and local electrical/telecoms regulations.
