Optický SFP transceiver CBO SFP-1G-ZX-120KM — 1G, singlemode, 120 km

CBO SFP-1G-ZX-120KM — 1G, Single-mode, 120 km is a 1 Gigabit SFP fiber optic transceiver designed for long-distance single-mode links up to 120 km. It fits the standard SFP form factor and is compatible with Allied Telesis equipment form factor, providing a single-port optical interface for uplinks, aggregation switches and WAN connections. The module supports reliable optical connectivity for telecom, data centre and enterprise network links where long reach and single-mode transmission are required.

Advantages

The transceiver delivers 1 Gbps full-duplex optical transmission over single-mode fiber for links up to 120 km, enabling long-reach connectivity without intermediate regeneration. Its SFP form factor ensures hot-pluggable installation in compatible transceivers slots and easy integration with existing network hardware. The product is built to industry optical standards for interoperability and stable link performance in WAN and metro applications.

Suitable for

• Long-distance single-mode fiber links between sites up to 120 km
• Uplink ports on switches and routers for aggregation or WAN connectivity
• Telecom and service provider point-to-point links
• Data centre interconnects and metro network segments
• Enterprise campus links requiring single-mode fiber reach

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: Single-mode (SM)
• Maximum reach: up to 120 km
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Optical interface: LC duplex connector (single-mode)
• Transmission mode: full-duplex serial optical link
• Typical applications: WAN, metro, data centre and telecom links

How to use

Install the SFP transceiver into a compatible SFP slot on the switch, router or media converter while the host device is powered on or off, as supported by hot-plug capability. Connect single-mode fiber with LC duplex connectors, ensuring the correct transmit/receive orientation. Check link status on the host device and verify optical power and signal levels if available in diagnostics. Configure the host port for 1 Gbps operation and appropriate VLAN or network settings as required by the network design.

Recommendations

Use clean, undamaged single-mode fiber and maintain correct connector cleanliness to preserve optical performance. Verify compatibility with the host device’s supported transceiver list or form-factor compatibility notes before deployment. For links near the maximum reach, confirm optical budget and consider dispersion and splice losses when planning the path.
