SFP transceiver CBO SFP-1G-ZX 1G 80 km jednovidový optický modul

CBO SFP-1G-ZX is a 1G SFP transceiver for single-mode fiber links up to 80 km. The module provides a single optical interface compatible with gigabit Ethernet and other 1G network equipment, enabling long-distance connections between switches, routers or media converters. It supports hot-plug installation in standard SFP ports and is intended for use in single-mode fiber infrastructures where extended reach is required.

Advantages

The transceiver offers a standardized SFP form factor for broad compatibility with networking devices that accept small form-factor pluggable modules. Its single-mode 80 km reach allows consolidation of fiber segments and reduces the need for intermediate devices. Hot-pluggable design simplifies installation and replacement without powering down equipment, and the optical interface provides electrical isolation and immunity to electromagnetic interference over long distances.

Suitable for

• Extending gigabit Ethernet links across campus or between buildings
• Interconnecting switches and routers over long single-mode fiber spans
• Connecting media converters to bridge copper and fiber segments
• Telecom or ISP access links requiring 1G single-mode transceivers

Key specifications

• Data rate: 1 Gbps
• Fiber type: single-mode
• Maximum link length: up to 80 km (typical single-mode fiber conditions)
• Form factor: SFP (small form-factor pluggable)
• Optical interface: single-fiber optical transmit/receive pair
• Wavelength: long-wavelength (ZX class, suitable for extended reach)
• Operating mode: unpowered hot-pluggable module

How to use

Insert the CBO SFP-1G-ZX module into an available SFP slot on a compatible switch, router or media converter until it clicks into place. Connect a single-mode fiber patch cable between the module and the remote device, ensuring correct transmit and receive orientation. Monitor link status via the host device LEDs or management interface. Replace the module by gently pulling the release latch and removing the module while the host remains powered if hot-swap is supported.

Recommendations

Use certified single-mode fiber (SMF) and quality connectors to achieve the specified 80 km reach. Verify compatibility with the host device's supported SFP modules and consult the device documentation for any vendor-specific interoperability notes. For long-distance links, perform power budget and loss calculations and use appropriate fiber testing tools to confirm link performance.
