SFP transceiver CBO SFP-1G-ZX-160KM 1.25Gbps single-mode 160 km

CBO SFP-1G-ZX-160KM is an SFP optical transceiver designed for Gigabit Ethernet links at 1.25 Gbps over single-mode fiber with a transmission range of up to 160 km. The module follows the standard SFP form factor and supports hot-pluggable installation, enabling quick replacement or upgrades without powering down network equipment. It is intended for long-distance connectivity between switches, routers and media converters in metro and WAN environments that require stable single-mode fiber links.

Advantages

The transceiver offers long-reach single-mode operation with a maximum span of 160 km, reducing the need for intermediate repeaters or amplifiers in many deployments. Its SFP size ensures compatibility with a wide range of network devices that accept SFP modules. Hot-pluggable capability simplifies maintenance and minimizes network downtime during hardware changes. The module is engineered to meet common Gigabit Ethernet optical interfaces and supports straightforward integration into existing fiber infrastructure.

Suitable for

• Long-distance Gigabit Ethernet links over single-mode fiber
• Interconnecting switches and routers in metro and WAN networks
• Connecting media converters and optical line equipment across extended spans
• Network edge sites and point-to-point fiber links requiring 160 km reach

Key specifications

• Data rate: 1.25 Gbps (Gigabit Ethernet)
• Fiber type: single-mode fiber (SMF)
• Maximum link distance: up to 160 km
• Form factor: SFP (Small Form-factor Pluggable)
• Wavelength band: typical for long-reach single-mode optics (ZX)
• Hot-pluggable: yes

How to use

Install the SFP module into an empty SFP slot of a compatible switch, router or media converter while the host device is powered on, taking care to align the module correctly with the slot guide rails. Connect single-mode fiber patch cords to the transmit and receive ports, observing correct polarity. Verify link status via the host device LEDs or management interface and configure network parameters as required for the Gigabit Ethernet interface. For safe handling, avoid touching the optical connector end faces and keep dust caps in place until connection.

Recommendations

Use high-quality single-mode fiber and maintain proper connector cleanliness to achieve the specified 160 km range. Verify compatibility with the network device vendor's SFP acceptance list or test interoperability prior to large-scale deployment. For links approaching the maximum distance, validate signal performance with optical power meters and consider inline amplification or dispersion management if required by the fiber plant.
