Transceptor SFP de fibra ótica CBO SFP-1G-LX-20KM — 1 Gbit/s, monomodo, 20 km

CBO SFP-1G-LX-20KM is a single-mode SFP fiber optic transceiver designed for 1 Gbps Ethernet links up to 20 km. The module offers a compact, hot-pluggable interface that fits standard SFP ports on switches, routers and media converters. It enables Ethernet extension over fiber to provide low-loss transmission and immunity to electromagnetic interference for point-to-point connections.

Advantages

The transceiver supports full-rate 1 Gbps throughput over single-mode fiber, allowing reliable data transfer across metropolitan or campus links. Its hot-pluggable SFP form factor simplifies installation and maintenance without powering down equipment. Optical transmission reduces susceptibility to electrical noise and ground loops compared with copper cabling, while the small footprint preserves port density on networking hardware.

Suitable for

• Extending Ethernet connections between buildings or across a campus up to 20 km
• Replacing or upgrading copper links to fiber for improved signal integrity
• Connecting switches, routers and media converters with SFP ports
• Use in networks requiring immunity to electromagnetic interference

Key specifications

• Data rate: 1 Gbps (full-duplex)
• Fiber type: single-mode
• Maximum link distance: up to 20 km (depending on fiber and channel conditions)
• Form factor: SFP (hot-pluggable)
• Connector type: LC duplex
• Wavelength: long wavelength single-mode transmission
• Typical use: point-to-point fiber Ethernet links

How to use

Insert the SFP transceiver into an available SFP slot on compatible network equipment until it clicks into place. Connect a single-mode LC duplex fiber patch cable between transceivers at each end of the link, ensuring correct transmit/receive orientation. Verify that the switch or router recognizes the module and that link/activity LEDs indicate an operational connection. Configure interface settings on your network device as required for speed, duplex and link protocols. To remove the module, power down the port if recommended by the equipment vendor and extract the transceiver by pressing the release mechanism.

Recommendations

Handle the transceiver and fiber connectors with care to avoid contamination; always use dust caps when connectors are not mated and clean connectors before installation. Match fiber type and connector polarity on both ends, and verify that link budget and fiber condition support the intended 20 km distance.
