Fiber optic SFP transceiver CBO SFP-1G-ZX-120KM-IX-BO, 1.25 Gbps, LC, single-mode, ZX, up to 120 km

The BlueOptics fiber optic SFP transceiver SFP-1G-ZX-120KM-IX-BO is a single-mode module that supports a data rate of 1.25 Gbps and uses an LC duplex connector. Engineered for extended-reach (ZX) links, it enables reliable point-to-point optical connections over distances up to 120 km. The module conforms to the standard SFP form factor and provides hot-pluggable installation for compatibility with a wide range of switches, routers and optical line equipment.

Advantages

This SFP transceiver offers extended reach for long-distance fiber links while maintaining a compact SFP footprint. Hot-pluggable capability simplifies maintenance and replacements without powering down host equipment. The LC duplex interface supports standard single-mode fiber cabling, and the module is designed for interoperability with networking devices that accept standard SFP optics.

Suitable for

• Long-distance Ethernet links between network sites or data centers
• WAN and MAN backbone connections
• Fiber channel links requiring 1.25 Gbps transceivers
• Upgrading switches and routers to support extended single-mode links

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single-mode
• Connector type: LC duplex
• Optical class: ZX (extended reach)
• Maximum reach: up to 120 km
• Form factor: SFP (small form-factor pluggable)
• Installation: hot-pluggable

How to use

Insert the SFP transceiver into a compatible SFP slot on your switch, router or optical line terminal while the host device is powered according to the manufacturer's guidelines. Connect LC duplex single-mode fiber patch cables to the transceiver’s ports, ensuring transmit and receive fibers are correctly aligned. Configure the network port on the host device for the appropriate speed and optical settings if required. Monitor link status and diagnostics via the host device to verify proper operation.

Recommendations

Use high-quality single-mode fiber and properly rated patch cables for links approaching the maximum reach. Verify compatibility with the host device for supported SFP optics and, if available, check transceiver diagnostics (DOM) to monitor optical power and temperature. For mission-critical links, consider testing the end-to-end optical budget before deployment.
