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

CBO SFP-1G-ZX-120KM-LS-BO is a compact SFP transceiver module that delivers 1.25 Gbit/s data transmission over single-mode fiber with an LC connector. Designed for long-distance links, this module uses a ZX-class wavelength to support reach up to 120 km, providing hot-pluggable optical connectivity for routers, switches and other networking devices. It is intended for deployment in WAN links, metro networks and point-to-point fiber connections where stable gigabit performance and low footprint are required.

Advantages

The module offers a small form factor that enables flexible installation in standard SFP ports and minimizes rack space. Its single-mode LC interface and ZX wavelength are optimized for long-reach connections, allowing reliable transmission over distances up to 120 km. Hot-pluggable capability makes maintenance and upgrades simpler without powering down equipment. The transceiver supports typical industrial temperature ranges and optical performance suitable for carrier-class links and enterprise WAN segments.

Suitable for

• Long-distance Ethernet links between sites and data centers
• Metro and carrier networks requiring ZX long-reach optics
• Point-to-point fiber connections for telecom and ISP infrastructures
• Upgrading switches and routers with SFP interfaces to support 1 Gbit/s single-mode links

Key specifications

• Data rate: 1.25 Gbit/s (nominal)
• Fiber type: single-mode fiber (SMF)
• Connector: LC duplex
• Maximum link distance: up to 120 km (single-mode, ZX wavelength)
• Wavelength class: ZX (long-reach)
• Form factor: SFP (hot-pluggable)
• Typical power consumption: low-profile SFP power budget (device-dependent)

How to use

Insert the SFP module into a compatible SFP port on a switch, router or optical device while the host is powered according to the equipment manual for hot-pluggable modules. Connect single-mode LC patch cords to the module’s LC duplex connector, observing correct transmit/receive orientation. Ensure fiber connectors and ports are clean before mating to avoid signal loss. Configure the host device interface for 1 Gbit/s operation if required and verify link status through device management tools or LED indicators.

Recommendations

For reliable long-distance operation, use quality single-mode fiber and low-loss connectors, maintain proper fiber routing to avoid tight bends, and perform regular inspections and cleaning of LC connectors. Confirm optical power budgets and host equipment compatibility before deployment, and follow the host vendor’s guidelines for supported SFP modules.
