SFP glasvezeltransceiver CBO SFP-1G-LX-20KM 1 Gbit/s singlemode 20 km

The CBO SFP-1G-LX-20KM is a singlemode SFP fiber optic transceiver module that supports 1 Gbps data transmission over optical links up to 20 km. Designed for insertion into standard SFP slots on switches, routers and media converters, this module provides an optical uplink option for enterprise networks, data centers and service provider backbones. The transceiver is hot-pluggable and follows the standard SFP form factor for broad compatibility with networking equipment that accepts 1 Gbps fiber modules.

Advantages

This SFP transceiver offers stable 1 Gbps performance for long-distance singlemode links, with a rated reach of up to 20 km. Its hot-pluggable design allows replacement or installation without powering down equipment, reducing downtime during maintenance. The standard SFP footprint ensures compatibility with a wide range of switches, routers and media converters, while optical transmission reduces electromagnetic interference compared with copper uplinks.

Suitable for

• Optical uplinks between switches and routers in enterprise networks
• Fiber connections to service provider networks and aggregation points
• Long-distance links within campus, data center or metro environments
• Media converters and SFP-equipped network appliances requiring 1 Gbps singlemode optics

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: Singlemode optical fiber
• Maximum link length: up to 20 km (singlemode)
• Connector type: LC duplex
• Form factor: Small Form-factor Pluggable (SFP)
• Wavelength range: long wavelength (typical LX class optics)
• Hot-pluggable: yes

How to use

Insert the transceiver into an available SFP port on a powered networking device until it seats firmly. Connect the LC duplex singlemode fiber cables, observing correct TX/RX orientation and using appropriate fiber patch cords. Confirm link status via the host device interface or LEDs; most equipment will auto-negotiate to 1 Gbps over the optical link. For safe removal, follow the device's hot-swap procedure or power-down if required by the host equipment.

Recommendations

Use high-quality singlemode fiber and LC connectors rated for long-distance links, keep fiber ends clean, and verify compatibility with the host device's supported SFP modules. For reliable operation over the full 20 km range, verify link budget and loss characteristics of the fiber run and avoid excessive bending or improper termination.
