SFP module CBO SFP-1G-ZX-160KM-SP-BO 1.25 Gbps single-mode LC 160 km

CBO SFP-1G-ZX-160KM-SP-BO is a single-port SFP optical transceiver that supports a 1.25 Gbps data rate for single-mode fiber with an LC connector. Engineered for long-distance Ethernet and telecom links, this transceiver provides point-to-point fiber connectivity with a maximum reach of up to 160 km. The module is hot-pluggable and designed for low power consumption, making it suitable for use in switches, routers and optical transport equipment where reliable uplinks and backbone extension are required.

Advantages

This SFP module offers long-reach transmission up to 160 km over single-mode fiber using an LC connector, enabling extended network links without intermediate repeaters. It supports 1.25 Gbps data transfer for gigabit Ethernet and telecom applications while maintaining low power consumption and hot-pluggable operation for easy installation and serviceability. The module is designed for compatibility with standard SFP slots and typical network equipment used in access, aggregation and core layers.

Suitable for

• Long-distance Ethernet uplinks between campus or metropolitan sites
• Telecom point-to-point links and leased-line connections
• Backbone and aggregation links in carrier or ISP networks
• Data center interconnects where single-mode fiber span is required

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Data rate: 1.25 Gbps
• Fiber type: Single-mode fiber (SMF)
• Connector: LC duplex
• Maximum reach: up to 160 km
• Wavelength: typical for long-reach single-mode (ZX class)
• Power: low power consumption, hot-pluggable operation

How to use

Insert the module into an available SFP slot on a compatible switch, router or media converter while the host device is powered on or off, as the module supports hot-pluggable installation. Connect single-mode LC fiber patch cords to the transmit and receive ports, ensuring correct polarity. Configure the network equipment for 1.25 Gbps operation or auto-negotiation according to the device manual. Monitor link status and optical power levels from the host device diagnostics if available to confirm a stable connection.

Recommendations

Use high-quality single-mode fiber and LC patch cords with correct polarity to achieve the specified 160 km reach. Verify compatibility with the host equipment and consult transceiver/vendor documentation for supported link budgets and optical power parameters. For extended runs approaching the maximum reach, check fiber attenuation, splice and connector losses, and consider using optical amplifiers or dispersion management when required.
