Glasvezel SFP-module CBO SFP-1G-ZX-120KM-MT-BO 1,25 Gbit/s singlemode 120 km LC

The BlueOptics Fiber optic SFP module CBO SFP-1G-ZX-120KM-MT-BO is a single-mode SFP transceiver engineered for long-distance optical links. Supporting a data rate of 1.25 Gbit/s, this compact hot-pluggable module uses an LC interface and is suited for point-to-point connections over single-mode fiber up to 120 km. Designed for installation in compatible SFP slots on switches, routers and media converters, the module enables WAN links and telecom-grade fiber connectivity while maintaining a small form factor for dense equipment racks.

Advantages

The module provides reliable long-reach performance with a 120 km range on single-mode fiber and a standardized LC connector for broad compatibility. Its SFP form factor allows hot-pluggable replacement or upgrades without powering down network equipment. Low-power operation and industry-standard transmission at 1.25 Gbit/s make it suitable for legacy Gigabit optical links and mixed-vendor environments. The component is intended for straightforward integration into existing network infrastructure.

Suitable for

• Long-distance point-to-point optical links between sites
• WAN connections and telecom access links
• Fiber extension for data centers and campus networks
• Use in compatible switches, routers and media converters with SFP slots

Key specifications

• Data rate: 1.25 Gbit/s (Gigabit optical)
• Optical mode: single-mode fiber
• Maximum link distance: up to 120 km
• Connector type: LC duplex
• Form factor: SFP (hot-pluggable)

How to use

Install the SFP module into a compatible SFP slot on a switch, router or media converter until it latches. Connect single-mode fiber with LC connectors, ensuring correct transmit/receive pair alignment. Observe fiber handling best practices to avoid bending beyond specified radius and to keep connectors clean using appropriate cleaning tools. After physical installation, verify link status and configure interface settings on the network device as required for 1.25 Gbit/s operation and any desired optical parameters.

Recommendations

Verify device compatibility with vendor-supported transceivers and confirm link budget for 120 km with your fiber type and any inline components. Use dust caps when modules are not connected, maintain connector cleanliness, and perform light-level testing after installation to ensure reliable operation over long distances.
