Overview
The Ruijie MINI-GBIC-LH40-SM1310 is a hot-pluggable SFP (mini‑GBIC) optical transceiver offering 1 Gbps single‑mode long‑reach connectivity. It operates at 1310 nm with LC duplex connector and supports links up to 40 km — ideal for campus interconnects, data‑centre uplinks and long‑reach metro links.

• Form factor: SFP (mini‑GBIC), hot‑pluggable
• Data rate: 1.063–1.25 Gbps (1000BASE‑LH)
• Wavelength: 1310 nm (single‑mode)
• Maximum reach: 40 km over single‑mode fibre (LC duplex)
• Digital Diagnostic Monitoring (DDM/DOM) supported
• Low power consumption (≤ 1.5 W typical)

Compliance & safety
RoHS compliant. Class 1 laser device. CE/UKCA status: INSUFFICIENT DATA — confirm with supplier if required for your market.

Use & installation notes

• Hot‑pluggable SFP — can be inserted or removed without powering down the host device, but follow the host vendor’s hot‑swap procedures.
• Observe ESD precautions when handling the module and keep optical dust caps on connectors until ready to terminate.
• Check compatibility lists on the host switch/router; branded Ruijie modules minimise compatibility risk versus third‑party compatibles.
• For long runs and critical links verify optical budget (Tx/Rx power and fibre attenuation) from the full datasheet prior to deployment.

Typical applications
Campus networks, data‑centre interconnect, MAN links, carrier access links where single‑mode 1 Gbps long‑reach optics are required.

If you require the detailed optical transmitter/receiver figures (Tx power min/max, receiver sensitivity, optical budget, BER) or an official PDF datasheet link for your listing, I can extract and append those exact values.
