SFP 1G LX Fiber Optic Transceiver CBO SFP-1G-LX-20KM — 20 km single‑mode

CBO SFP-1G-LX-20KM is a 1 Gbps SFP fiber optic transceiver designed for single‑mode links up to 20 km. The module supports 1G Ethernet/LX transport via an LC connector and is compatible with switches, routers and media converters that accept standard SFP modules. It offers a compact hot‑pluggable form factor, low power consumption and stable optical transmission for backbone extension and point‑to‑point connections over single‑mode fiber.

Advantages

The transceiver delivers a reliable 1 Gbps data rate over distances up to 20 km on single‑mode fiber, reducing the need for intermediate repeaters. Its LC connector and standard SFP form factor ensure broad compatibility with networking equipment from various vendors. Low power consumption and a compact size simplify rack deployment and minimize additional cooling requirements. Optical transmission provides electrical isolation and immunity to electromagnetic interference on long links.

Suitable for

• Extending network backbones between buildings or floors
• Connecting switches, routers and media converters over single‑mode fiber
• Point‑to‑point links in campus, data center or metropolitan networks
• Replacing damaged or outdated SFP modules in existing infrastructure

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: single‑mode
• Maximum reach: up to 20 km
• Connector type: LC duplex
• Transmission type: LX (long wavelength single mode)
• Form factor: SFP (hot‑pluggable)
• Typical power consumption: low (device designed for energy‑efficient operation)

How to use

Insert the SFP module into a compatible SFP slot on a switch, router or media converter until it clicks into place. Connect an LC duplex single‑mode fiber patch cable to the module, observing correct TX/RX orientation. Configure the network ports on both ends as required for 1 Gbps operation and check link status indicators to confirm optical synchronization. Hot‑swap capability allows replacement or installation without powering down supported equipment.

Recommendations

For reliable performance, use single‑mode fiber rated for long‑reach links and quality LC connectors. Verify device compatibility with vendor documentation and ensure transceiver firmware or switch port settings match 1 Gbps LX operation. Keep connectors clean and protected with dust caps when not in use to maintain optical performance over time.
