Ricetrasmettitore SFP CBO SFP-1G-ZX-120KM-CO-BO 1,25 Gbit/s LC Singlemode 120 km

The SFP transceiver CBO SFP-1G-ZX-120KM-CO-BO is a single-port optical module that delivers a 1.25 Gbps data rate over single-mode fiber using an LC connector. Optimized for ZX wavelength and long-reach links, this compact hot‑swappable SFP module supports transmissions up to 120 km, making it suitable for backbone, metro and uplink connections in network equipment with SFP slots.

Advantages

This transceiver offers long-distance reach without intermediary repeaters and fits standard SFP interfaces for easy insertion and removal. The LC connector and single-mode design ensure low attenuation over extended spans, while the 1.25 Gbps data rate supports Gigabit Ethernet and similar serial optical protocols. The module's compact form factor and hot‑swappable capability simplify upgrades and maintenance in rack-mounted and industrial network devices.

Suitable for

• Long-distance backbone links between sites up to 120 km apart
• Metro aggregation and access networks requiring single-mode optics
• Fiber uplinks for switches, routers and media converters
• Link extension and point-to-point optical connections

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single-mode fiber
• Connector: LC duplex
• Optical reach: up to 120 km
• Wavelength window: ZX (long-reach optimized)
• Form factor: SFP, hot‑swappable

How to use

Install the SFP module into a compatible SFP slot on network equipment until it clicks into place. Connect single-mode LC fibers to the module's LC duplex connector, observing correct TX/RX orientation. Configure the connected devices for 1.25 Gbps operation and verify link status using device management tools. When removing the module, power down the port if required by your equipment, then pull the module straight out to avoid fiber stress.

Recommendations

Use low-loss single-mode patch cables and ensure proper connector cleaning to maintain signal integrity over long spans. Verify compatibility with your switch or router vendor's supported optics list and monitor optical receive power and error counters to confirm reliable operation.
