Fiber optic SFP module CBO SFP-1G-ZX-160KM-IA-BO 1.25 Gbps LC for 160 km single-mode links

CBO SFP-1G-ZX-160KM-IA-BO is a fiber optic SFP transceiver module designed for long-distance single-mode connections. Supporting a data rate of 1.25 Gbps and featuring an LC duplex connector, this module delivers reliable optical links for network equipment such as switches, routers and media converters. The small form-factor pluggable design allows hot-swappable installation for fast deployment and minimal downtime on WAN or point-to-point fiber links up to 160 km.

Advantages

The module combines long reach capability with a compact SFP form factor and industry-standard LC interface, ensuring compatibility with a wide range of network devices. With support for 1.25 Gbps throughput and single-mode operation, it provides stable optical performance over extended distances. Hot-pluggable installation simplifies maintenance and upgrades, while passive cooling and low power consumption suit use in rack-mounted equipment and media converters.

Suitable for

• Point-to-point fiber links between buildings or data centres over long distances
• WAN uplinks for carriers and service providers
• Extending enterprise networks across campuses or remote sites
• Connecting routers, switches and media converters that accept SFP transceivers

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Data rate: 1.25 Gbps (1250 Mbps)
• Fiber type: Single-mode fiber
• Maximum link distance: up to 160 km
• Connector: LC duplex
• Wavelength: suitable for long-reach (ZX) optical transmission
• Hot-swappable: yes

How to use

Insert the SFP transceiver into a compatible SFP port on a switch, router or media converter until it clicks into place. Connect LC duplex single-mode fiber patch cables between transceivers at each end of the link, observing transmit/receive orientation. Verify link status and negotiate the appropriate data rate via the network device management interface. For equipment that supports hot-plugging, the module can be replaced or installed without powering down the host device. Follow standard electrostatic discharge (ESD) precautions when handling the transceiver and keep dust caps on connectors when not in use.

Recommendations

Use high-quality single-mode fiber and properly terminated LC connectors to achieve the specified reach. Ensure compatible device settings for fiber type and speed, and perform link testing after installation. Protect long-distance fiber runs from physical damage and excessive bends to maintain signal integrity.
