Transceiver CBO SFP-1G-LX-20KM optický kábel 1G 20 km

CBO SFP-1G-LX-20KM Fiber Optic 1G 20 km is a single-mode fiber SFP transceiver designed to provide a 1 Gbps uplink with transmission distances up to 20 kilometres. The module supports hot-pluggable operation for straightforward installation into compatible SFP ports on switches, routers and media converters. It is intended for deployment in backbone, campus and enterprise networks where stable long-distance Gigabit connectivity over single-mode fiber is required.

Advantages

The transceiver offers stable 1 Gbps performance and supports link distances up to 20 km on single-mode fiber, enabling extended reach without signal regeneration. Hot-pluggable design simplifies replacement and upgrades without powering down equipment. The module follows standard SFP form-factor dimensions for wide compatibility with networking hardware that accepts SFP modules.

Suitable for

• Long-distance Gigabit uplinks between switches and routers
• Campus and university backbone connections
• Enterprise site-to-site fiber links
• Media converters and fiber extension applications

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: single-mode
• Maximum reach: up to 20 km
• Form factor: SFP (small form-factor pluggable)
• Optical wavelength: typical long-wave (compatible with LX optics)
• Connector type: duplex LC
• Hot-pluggable: yes

How to use

Insert the SFP-1G-LX-20KM module into an empty SFP slot on a compatible switch, router or media converter until it clicks into place. Connect the single-mode fiber cable using a duplex LC connector, ensuring proper alignment and clean connectors to minimise insertion loss. Configure the connected devices for 1 Gbps operation and verify the link status through the device management interface or link LEDs. For safe removal, follow the host equipment procedure to prevent ESD or mechanical damage.

Recommendations

Use single-mode fiber with appropriate launch power and receiver sensitivity margins; keep connectors clean and protected when not in use. Verify compatibility with your switch or router vendor list for third-party SFP modules and perform link tests after installation to confirm expected throughput and reach.
