Módulo SFP CBO SFP-1G-ZX-120KM-DL-BO — 1,25 Gbit/s, monomodo LC, ZX, hasta 120 km

The CBO SFP module SFP-1G-ZX-120KM-DL-BO is a Small Form-factor Pluggable (SFP) transceiver designed for long-distance single-mode fiber links. It supports a 1.25 Gbit/s data rate, uses an LC duplex connector and operates on the ZX wavelength, enabling optical connections across extended distances up to 120 km. The module is intended for insertion into compatible SFP ports on switches, routers and media converters to create reliable optical uplinks and backbone links.

Advantages

This SFP transceiver provides a stable 1.25 Gbit/s throughput for single-mode fiber, with an LC duplex interface that fits standard SFP slots. The ZX wavelength and optical power budget are optimized for long-reach links up to 120 km, reducing the need for intermediate amplification or regeneration in many network topologies. The module follows SFP form-factor specifications, allowing hot-pluggable installation and straightforward integration into existing network equipment that accepts SFP optics.

Suitable for

• Long-distance optical uplinks between switches and routers
• Backbone and campus network extension over single-mode fiber
• Media converters and optical line terminations requiring 1.25 Gbit/s links
• Point-to-point fiber links where ZX wavelength reach is required

Key specifications

• Data rate: 1.25 Gbit/s (SFP 1G)
• Fiber type: single-mode fiber (SMF)
• Connector: LC duplex
• Wavelength: ZX (extended reach wavelength)
• Maximum reach: up to 120 km (depending on fiber quality and link conditions)
• Form factor: SFP, hot-pluggable

How to use

Insert the module into a compatible SFP port on a switch, router or media converter while the device is powered on or off, observing anti-static precautions. Connect LC duplex single-mode fiber patch cables observing correct transmit-to-receive orientation. After installation, verify link status through the host device interface and confirm correct data rate and optical levels. Ensure both ends of the link use compatible wavelengths and fiber specifications for optimal performance.

Recommendations

For reliable 120 km links, use single-mode fiber with low attenuation and appropriate dispersion characteristics, ensure clean LC connectors, and verify end-to-end optical budget including splices and connectors. Confirm compatibility with the host device's supported SFP transceiver list and monitor optical power levels and error counters during initial deployment and maintenance.
