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

CBO SFP-1G-ZX-120KM-LC-BO is an SFP optical transceiver module designed for 1.25 Gbit/s Ethernet links over single-mode fiber. The module features an LC duplex connector and supports long-reach ZX transmission up to 120 km, making it suitable for metro and long-haul network segments. It delivers compatible interfacing for standard SFP ports and is intended for use in uplinks, backbone extensions and other scenarios requiring reliable low-latency optical connectivity.

Advantages

The transceiver provides long-distance transmission capability in a compact SFP form factor, enabling extended fiber links without additional inline equipment. Its single-mode LC interface ensures stable performance over long spans while maintaining low power consumption and broad device compatibility. The module is engineered for plug-and-play installation in systems that accept industry-standard SFP modules and supports stable optical signal characteristics for network continuity.

Suitable for

• Metro and long-haul fiber links
• Network uplinks between switches and routers
• Fiber backbone extensions in campus or carrier networks
• Low-latency connections for data center interconnects

Key specifications

• Data rate: 1.25 Gbit/s (1250 Mbit/s)
• Fiber type: single-mode fiber (SMF)
• Connector type: LC duplex
• Wavelength class: ZX long-reach transmission
• Maximum reach: up to 120 km (dependant on fiber and link budget)
• Form factor: SFP (small form-factor pluggable)
• Interface: optical 1G Ethernet

How to use

Insert the SFP transceiver into a compatible SFP slot on your switch, router or optical device following the vendor's hot-plugging guidelines. Connect a single-mode LC duplex fiber patch cable to the module, ensuring correct TX/RX orientation. Verify link status and optical power levels via device interfaces or management tools. If required, configure the host device for 1G Ethernet operation and confirm that any vendor-specific settings or firmware are compatible with the installed module.

Recommendations

To achieve reliable 120 km links, use high-quality single-mode fiber with appropriate attenuation characteristics, ensure proper LC connector cleaning and inspect end faces before connection, and validate link budget including patch panels and splices. Check device compatibility lists and update host equipment firmware if necessary to avoid interoperability issues.
