SFP transceiver CBO SFP-1G-ZX 1G 80 km single-mode fiber

The BlueOptics SFP transceiver CBO SFP-1G-ZX is a single-mode fiber optic module that supports 1 Gbps data transmission over distances up to 80 km. Designed for standard SFP slots, this compact transceiver enables long-reach uplinks and backbone links in metro and enterprise networks. It is compatible with equipment accepting Lenovo-compatible SFP modules and is intended for use where stable, low-latency optical connections are required.

Advantages

This SFP transceiver provides a predictable 1 Gbps throughput with optical reach suitable for long-distance connections up to 80 km. Its small form factor allows direct insertion into standard SFP ports, reducing the need for copper cabling and intermediate repeaters. The module supports single-mode fiber which minimizes signal attenuation over long spans and helps maintain consistent performance for uplinks and point-to-point links.

Suitable for

• Long-distance uplinks between data centers or aggregation points
• Metro access and carrier Ethernet links
• Enterprise backbone extensions across campus or between buildings
• Service provider fiber segments requiring single-mode connectivity

Key specifications

• Data rate: 1 Gbps (SFP standard)
• Fiber type: single-mode (SMF)
• Maximum reach: up to 80 km (dependent on fiber quality and channel conditions)
• Form factor: SFP (small form-factor pluggable)
• Optical interface: duplex LC connector
• Operating wavelength: typical for long-reach single-mode optics (ZX range)

How to use

Insert the transceiver into a compatible SFP slot on a switch, router or media converter until it latches. Connect duplex single-mode fiber using LC connectors, observing correct transmit/receive alignment. Verify link status and speed through the host device management interface and confirm optical power levels where applicable. When removing the module, power down the port if recommended by the device vendor and pull the transceiver straight out to avoid damage.

Usage recommendations

Use certified single-mode fiber and clean LC connectors to ensure optimal performance. Check compatibility with the host device prior to installation and follow manufacturer guidelines for ESD handling and operating temperature ranges. For distances near the maximum reach, confirm end-to-end optical budget and consider fiber attenuation, splices and connector losses.
