SFP-moduuli CBO SFP-1G-ZX-120KM-VA-BO 1,25 Gbit/s yksimuoto LC, 120 km

SFP CBO SFP-1G-ZX-120KM-VA-BO is a single-mode SFP transceiver module that operates at 1.25 Gbps and uses an LC duplex connector to support long-distance fiber links up to 120 km. Intended for telecom and enterprise network environments, this compact hot-pluggable unit enables gigabit Ethernet and optical transport connections over single-mode fiber with stable performance and straightforward integration into compatible SFP ports.

Advantages

The module delivers long-reach connectivity with a maximum distance of 120 km while maintaining a compact SFP form factor suitable for rack-mounted switches and optical equipment. Its LC interface and single-mode optical design provide low-loss transmission for backbone or point-to-point links. Hot-pluggable operation allows on-the-fly upgrades or replacements without powering down equipment, and compatibility with standard 1.25 Gbps SFP ports ensures broad interoperability in mixed-vendor environments.

Suitable for

• Long-distance point-to-point fiber links between sites
• Backbone and metropolitan optical transport networks
• Upgrading switches and routers to support single-mode gigabit connectivity
• Telecom and enterprise network segments requiring reliable long-reach optics

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single-mode fiber (SMF)
• Connector type: LC duplex
• Maximum reach: up to 120 km
• Form factor: SFP (small form-factor pluggable)
• Optical interface: 1.25 Gbit/s serial optical interface
• Hot-pluggable: yes

How to use

Insert the SFP module into a compatible SFP slot on a switch, router or media converter until it clicks into place. Connect single-mode fiber cables with LC connectors to the transmit and receive ports, observing correct polarity. Verify link status on the host device and configure the interface for 1 Gbps operation if required by your equipment. For safe removal, use the device's recommended procedure to deactivate the port or power state and gently pull the module from the slot, protecting the fiber connectors with dust caps when not in use.

Recommendations

Use high-quality single-mode fiber and maintain clean LC connector endfaces to ensure consistent signal performance. Ensure transceiver compatibility with the host device and confirm link settings in the device management console. For routes near the maximum reach, verify optical budget, link loss, and consider using optical amplifiers or better-performing fiber if necessary.
