Overview

The Ruijie GE‑SFP‑LX20‑SM1550‑BIDI is a 1.25 Gbps SFP (Mini‑GBIC) single‑mode bi‑directional (BiDi) optical transceiver. It uses a single fibre (simplex LC) to provide point‑to‑point links up to 20 km and is intended for data centre, campus and network interconnect use in switches, routers and servers. Supports hot‑plug and digital diagnostic monitoring (DDM/DOM) for real‑time optical diagnostics.

Key features

• Single‑fibre BiDi — saves fibre by using one strand (paired with complementary module).
• 1.25 Gbps (1000BASE‑LX) operation — compatible with Gigabit fibre ports.
• Wavelengths: TX 1550 nm / RX 1310 nm (this SKU).
• Reach: up to 20 km over single‑mode fibre (SMF).
• Digital Diagnostic Monitoring (DDM/DOM) for optical parameter reporting.
• Low power consumption (≤ 1.5 W typical). SFP MSA compliant and hot‑pluggable.

Compatibility & safety

• BiDi modules must be used in complementary pairs (this unit pairs with the 1310TX/1550RX module at the far end).
• Compliant with RoHS and Class 1 laser safety. Check device compatibility and local UKCA/CE requirements where applicable.
• Intended for professional installation; follow official datasheet and supplier installation guidance for optical budgeting and connector handling.
