SFP transceiver CBO SFP-1G-ZX-160KM-LS-BO — 1.25 Gbps, LC, ZX, up to 160 km

Compact SFP transceiver CBO SFP-1G-ZX-160KM-LS-BO delivers 1.25 Gbps full-duplex data transfer over single-mode fiber using an LC connector and ZX (extended wavelength) optics. The module is engineered for long-distance fiber links up to 160 km and is compatible with standard SFP ports on switches, routers and media converters. It supports WAN, metro and long-reach network infrastructures where stable gigabit optical connectivity is required.

Advantages

The transceiver provides a combination of long reach and low power consumption in a compact SFP form factor, enabling gigabit links without occupying larger optical module slots. ZX optics extend the transmit wavelength range for longer spans while maintaining signal integrity, and the LC duplex connector ensures compatibility with common single-mode patch cables. The module is suitable for hot-plug installation and typical SFP management interfaces, facilitating simple replacement or upgrade of existing fiber links.

Suitable for

• Long-distance fiber uplinks between core and aggregation switches
• WAN and metro ring connections requiring up to 160 km reach
• Backbone links and remote site connectivity
• Integration with routers, switches and media converters that have SFP slots

Key specifications

• Data rate: 1.25 Gbps (gigabit Ethernet/SONET/SDH compatible)
• Fiber type: single-mode fiber (SMF)
• Connector: LC duplex
• Optical type: ZX (extended wavelength) for long reach
• Maximum reach: up to 160 km (dependant on fiber type and link budget)
• Form factor: SFP (small form-factor pluggable)

How to use

Install the SFP module into an available SFP slot on compatible network equipment while the device is powered on or off, following vendor guidance for hot-plug handling. Connect LC duplex single-mode fiber patch cables with correct polarity and verify link status through the host device management interface. Configure the connected interfaces on switches or routers to the appropriate speed and duplex settings if required by the host system. Monitor optical levels and error statistics to ensure the link meets expected performance across the deployed fiber span.

Recommendations

For reliable operation over distances approaching 160 km, verify end-to-end link budget, fiber attenuation, and any intermediate splice or connector losses. Use single-mode fiber with appropriate dispersion characteristics and keep connectors clean. Confirm compatibility with the host device SFP vendor policy and consult optical power specifications when designing long-reach links.
