SFP-glasvezeltransceiver CBO SFP-1G-ZX-120KM-CH-BO 1,25 Gbps LC ZX 120 km

CBO SFP-1G-ZX-120KM-CH-BO is a single‑channel SFP fiber transceiver that supports a 1.25 Gbps data rate with an LC connector and ZX-class transmit wavelength for long‑reach single‑mode links up to 120 km. The module is designed for insertion into standard SFP slots of switches, routers and other optical networking equipment and provides a hot‑swappable solution for extending fiber Ethernet and Gigabit links in telecom and enterprise networks.

Advantages

The transceiver delivers long‑distance connectivity with a ZX wavelength optimized for 120 km single‑mode links while maintaining a compact SFP form factor. It supports hot‑swap installation for minimal service disruption and is compatible with commonly used SFP ports in network hardware. The module provides reliable optical performance suitable for backbone, metro and point‑to‑point connections and reduces the need for intermediate regeneration or additional active equipment on long spans.

Suitable for

• Long‑reach single‑mode fiber links in telecom networks
• Point‑to‑point Gigabit Ethernet connections between sites
• Backbone or metro links in enterprise and data center environments
• Upgrading switches and routers to support extended fiber distances

Key specifications

• Data rate: 1.25 Gbps
• Form factor: SFP (small form‑factor pluggable)
• Connector type: LC duplex
• Optical reach: up to 120 km over single‑mode fiber
• Wavelength class: ZX (long‑reach wavelength)
• Operating mode: single‑channel simplex/duplex optical transceiver
• Hot‑swappable for in‑service replacement

How to use

Insert the SFP transceiver into a compatible SFP slot on your switch, router or optical device until it latches. Connect single‑mode LC patch cables to the transmit and receive ports, observing correct polarity. After installation, verify link status and negotiated speed via the host device’s management interface or indicator LEDs. For removal, power down the port if recommended by the equipment manufacturer, depress the module latch and gently withdraw the transceiver.

Recommendations

Use IEC/ITU‑compliant single‑mode fiber with appropriate attenuators if necessary for long runs. Ensure clean LC connectors and use dust caps when the module is unused. Verify equipment compatibility and refer to the host device documentation for SFP support and any required configuration steps to enable 1.25 Gbps links.
