SFP optical transceiver CBO SFP-1G-ZX-160KM-RW-BO 1.25 Gbps 1310/1550 nm LC single-mode 160 km

CBO SFP-1G-ZX-160KM-RW-BO is a 1.25 Gbps SFP optical transceiver designed for long-distance single-mode fiber links up to 160 km. The module uses ZX-class wavelength operation (typically transmitting at 1310 nm and receiving at 1550 nm) and an LC duplex connector to provide a compact, hot-pluggable solution for uplink, WAN or point-to-point connections in telecom and enterprise networks. The transceiver supports standard SFP electrical and mechanical interfaces for easy integration into switches, routers and optical transport equipment that accept SFP form-factor modules.

Advantages

The transceiver provides reliable long-reach transmission with a data rate of 1.25 Gbps while maintaining low power consumption and passive cooling. Its LC duplex connector and SFP form factor enable simple installation and replacement without system downtime. The ZX wavelength pairing allows operation over very long single-mode distances, reducing the need for intermediate amplification or regeneration in many deployments. The module is compatible with standard SFP sockets and supports hot-plug functionality for maintenance flexibility.

Suitable for

• Long-distance point-to-point fiber links in metro and long-haul networks
• Uplink connections between switches and routers in enterprise WANs
• Telecom access and aggregation layers requiring single-mode reach
• Link extension between data centers and remote sites

Key specifications

• Data rate: 1.25 Gbps (SFP optical interface)
• Wavelength: ZX class (typical transmit/receive wavelengths around 1310/1550 nm)
• Fiber type: Single-mode fiber
• Maximum link distance: up to 160 km (dependant on fiber and link budget)
• Connector type: LC duplex
• Form factor: SFP (hot-pluggable)
• Cooling: Passive

How to use

Install the transceiver into a compatible SFP socket of your network device while the device is powered on or during maintenance windows, using the hot-plug capability if supported. Connect single-mode LC duplex fiber patch cords ensuring correct transmit-to-receive orientation. Verify link status and optical parameters via the host device management interface or monitoring tools to confirm proper operation and sufficient optical power margin. When removing the module, power down the port if recommended by the equipment vendor and handle the optical interfaces with dust caps to avoid contamination.

Recommendations

For reliable long-distance operation, verify the fiber type, attenuation and connector quality along the link and ensure the total loss does not exceed the module's link budget. Use clean LC connectors and appropriate single-mode patch cords, and follow device vendor guidance on supported SFP transceivers to maintain compatibility and warranty conditions.
