• Fiber access links in telecom and service provider environments
• Point-to-point single-mode fiber links up to 20 km

Key specifications

• Data rate: 1 Gbps
• Fiber type: single-mode
• Maximum reach: 20 km
• Form factor: SFP (small form-factor pluggable)
• Optical interface: LC duplex
• Hot-pluggable: yes
• Typical power consumption: low (device-specific values depend on host)

How to use

Insert the SFP module into a compatible SFP port on a switch, router or media converter while the host device is powered on or off, as supported by the equipment. Attach an LC-duplex single-mode fiber patch cable to the module, ensuring correct transmit/receive orientation. Configure the host network device for 1 Gbps operation and verify link status through device management interfaces or LED indicators. For link commissioning, perform basic optical checks such as inspecting connectors for cleanliness and confirming end-to-end continuity.

Recommendations

Prior to installation, clean fiber connectors with appropriate tools and verify compatibility with the host device. Use single-mode fiber and LC connectors rated for the intended reach. Monitor link status after insertion and follow device manufacturer guidance for firmware or configuration adjustments. Store spare modules in anti-static packaging and avoid exposing the transceiver to excessive dust, moisture or mechanical stress.
