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

CBO SFP-1G-ZX-120KM-SP-BO is an SFP transceiver module designed for single-mode fiber links with an LC connector. Supporting a data rate of 1.25 Gbps and a transmission reach of up to 120 km, this compact, hot-pluggable module provides optical uplink connectivity for network devices such as switches, routers and media converters. The module is intended to simplify installation and replacement while enabling long-distance links in telecom and enterprise environments.

Advantages

The module offers long-reach single-mode transmission at gigabit speed with a compact SFP form factor that fits standard SFP ports. Hot-pluggable design allows insertion and removal without powering down the host device. LC connector and single-mode optics ensure low-loss links over extended distances, reducing the need for intermediate repeaters. Compatibility with a wide range of networking equipment supports flexible deployment in access, distribution and core segments.

Suitable for

• Long-distance fiber uplinks between switches and routers
• Telecom and carrier aggregation links requiring single-mode optics
• Campus and metropolitan area network (MAN) connections
• Media converters and optical line cards in enterprise networks

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single-mode
• Connector: LC duplex
• Maximum reach: up to 120 km
• Form factor: SFP (small form-factor pluggable)
• Optical wavelength: typical for long-haul single-mode (ZX class)
• Hot-pluggable: yes

How to use

Insert the SFP module into a compatible SFP slot on a switch, router or media converter until it clicks into place, taking care to align the module with the port. Connect LC-terminated single-mode fiber patch cables to the module’s connector, observing transmit and receive orientation. After insertion, verify link status and speed on the host device and adjust transceiver or port settings if required. For safe removal, follow the host device procedure to deactivate the port if necessary, then gently pull the module out using the release mechanism.

Recommendations

Use high-quality single-mode fiber and LC connectors, maintain proper fiber cleanliness, and follow manufacturer guidelines for SFP compatibility and operating temperature ranges. For distances approaching the module’s maximum reach, ensure end-to-end loss budget is calculated and consider using dispersion management or amplification if required by the link design.
