SFP 1G LX optische transceiver CBO SFP-1G-LX-20KM, singlemode, 20 km bereik

CBO SFP-1G-LX-20KM is an SFP 1G LX optical transceiver from BlueOptics designed for single-mode fiber links with a maximum reach of 20 km. The module conforms to standard SFP form factor and provides 1 Gbps optical connectivity for compatible switches, routers and media converters. It is intended for point-to-point fiber extension where a compact, hot-pluggable transceiver is required to establish reliable long-distance links in campus, metro and enterprise backbone environments.

Advantages

The module supports 1 Gbps data rates over single-mode fiber up to 20 km, offering a balance of distance and throughput for access and aggregation layers. Its standard SFP form factor ensures broad compatibility with equipment that accepts SFP transceivers, while hot-pluggable design simplifies installation and replacement without powering down connected devices. The single-mode optical design minimizes signal degradation over longer runs compared with multimode solutions, helping maintain stable link performance in typical network deployments.

Suitable for

• Fiber links between switches or routers in campus networks
• Enterprise backbone connections requiring up to 20 km reach
• Metro edge links and point-to-point fiber extensions
• Media converters and network devices with SFP ports

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: single-mode fiber
• Maximum reach: up to 20 km (single-mode)
• Wavelength: LX-class transmission (typical long wavelength around 1310 nm)
• Optical interface: duplex LC connector
• Hot-pluggable: yes

How to use

Insert the SFP-1G-LX-20KM module into an available SFP port on a switch, router or media converter until it seats securely. Connect single-mode fiber cables with LC connectors to the module's duplex optical interface, observing correct transmit/receive pairing. Ensure the connected network devices are configured for 1 Gbps optical links and that fiber runs meet single-mode specifications and attenuation budgets for distances up to 20 km. After insertion, verify link status through the host device's management interface or LED indicators.

Recommendations

Use single-mode fiber with appropriate attenuation and end-face cleanliness to achieve reliable performance up to 20 km. Avoid bending or stressing fiber cables near the connectors and confirm polarity when connecting duplex LC patch cords. If used in mixed-vendor environments, verify compatibility and supported link diagnostics in the host device to ensure stable operation.
