SFP transceiver CBO SFP-1G-LH for QNAP — 1 Gbps, long‑haul single‑mode fiber

The BlueOptics CBO SFP-1G-LH is a compact SFP transceiver compatible with QNAP devices that provides a 1 Gbps uplink over long‑haul single‑mode fiber. Designed for direct insertion into standard SFP ports, this module enables fiber connectivity for switches, NAS systems and routers that require reliable 1G LH links. The transceiver supports long‑distance optical transmission while maintaining stable throughput and low latency, making it suitable for backbone uplinks and inter-building connections.

Advantages

This SFP transceiver offers single‑mode long‑haul operation at 1 Gbps in a hot‑swappable SFP form factor, allowing fast installation without service interruption. It is compatible with QNAP hardware that accepts third‑party SFP modules and is engineered to deliver consistent optical performance and signal integrity across extended distances. The compact design reduces space consumption in network racks and helps maintain efficient airflow.

Suitable for

• Long‑distance uplinks between buildings or data centers over single‑mode fiber
• Fiber connections for QNAP NAS devices to switches and routers
• Backbone and aggregation links in small and medium enterprise networks
• Replacing or extending existing 1 Gbps fiber ports

Key specifications

• Interface: SFP form factor for insertion into standard SFP ports
• Data rate: 1 Gbps full duplex
• Fiber type: single‑mode fiber (SMF)
• Range: designed for long‑haul optical transmission (LH)
• Connector type: LC duplex optical connector
• Power consumption: low power design suitable for dense installations
• Operating temperature: industrial/standard ranges depending on device requirements

How to use

Power off the host device if recommended by the manufacturer, then insert the SFP transceiver into an available SFP slot until it seats firmly. Connect single‑mode LC duplex fiber patch cables to the transceiver, observing transmit and receive polarity. After installation, verify link status on the QNAP device or switch management interface and confirm negotiated speed is 1 Gbps. If required, consult the QNAP hardware documentation to ensure compatibility and enable any vendor-specific settings for third‑party modules.

Recommendations

Use quality single‑mode LC duplex patch cables and proper fiber management to preserve signal integrity. Test end‑to‑end link budget and optical power levels when deploying long‑haul links, and follow the host device vendor guidance for firmware and compatibility settings to ensure stable operation.
