SFP-lähetin-vastaanotin CBO TN-SFP-LXB22-BO, kuitu 1250 Mbit/s, 20 000 m

CBO TN-SFP-LXB22-BO is an SFP fiber optic transceiver that supports a 1250 Mbit/s data rate and a single-mode transmission range up to 20,000 m. The module is built to fit standard SFP ports and provides a long-reach optical connection for uplink and backbone links in telecom, enterprise and campus networks. It enables single-fiber single-mode connectivity for devices with SFP interfaces and is suitable for installations where reliable point-to-point fiber links are required.

Advantages

The transceiver offers a long transmission distance of up to 20 km while maintaining a 1250 Mbit/s line rate, making it suitable for long-reach fiber links. Its SFP form factor ensures compatibility with a wide range of switches, routers and optical equipment with standard SFP slots. The single-mode design provides low attenuation over long distances and predictable optical performance. The module is compact and hot-pluggable, allowing replacement or upgrades without shutting down equipment.

Suitable for

• Long-distance uplink and backbone connections between switches and routers
• Telecom and carrier access links requiring single-mode fiber
• Enterprise campus interbuilding connections and data center links
• Network equipment upgrades where SFP modularity is required

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Data rate: 1250 Mbit/s (1.25 Gbit/s)
• Transmission medium: single-mode optical fiber
• Maximum link distance: up to 20,000 m (20 km)
• Connector type: standard SFP optical interface (LC typical)
• Operational mode: simplex or duplex single-mode transmission depending on cabling

How to use

Insert the SFP transceiver into a compatible SFP port on a switch, router or optical device until it latches securely. Connect the single-mode fiber patch cable to the module's optical connector, observing correct fiber polarity and connector type. Power on the devices and verify link status via the equipment's LEDs or management interface. Monitor signal levels and link integrity using the host device's diagnostic tools if available. For replacement, hot-swap the module following the device manufacturer's instructions.

Recommendations

Use single-mode fiber with appropriate attenuation and connectors for distances up to 20 km. Ensure fiber connectors are clean before mating to prevent signal loss. Match the transceiver optical wavelength and link budget with the remote module or passive components. Follow equipment vendor compatibility notes and, when possible, test links during maintenance windows to avoid service disruption.
