SFP transceiver CBO SFP-1G-ZX-120KM-NV-BO 1.25 Gbps 120 km single‑mode 1250 nm

CBO SFP-1G-ZX-120KM-NV-BO is a BlueOptics SFP optical transceiver module that supports 1.25 Gbps Ethernet links over single‑mode fiber. Operating at a wavelength of 1250 nm, the module is designed for long‑reach connections up to 120 km and offers hot‑swappable compatibility with a wide range of network equipment including switches, routers and media converters. Compact and industry‑standard in form factor, it provides an optical interface for extending backbone links, metro circuits and dedicated point‑to‑point fiber runs where stable single‑mode transmission is required.

Advantages

The transceiver delivers long‑distance optical connectivity with low power consumption and stable performance over single‑mode fiber. Its hot‑swappable design simplifies field upgrades and replacements without powering down network equipment. Conformance to standard SFP form factor ensures broad interoperability with devices that accept SFP modules, enabling flexible deployment across different network architectures.

Suitable for

• Long‑reach backbone links between data centers or campus sites
• Metro and carrier access networks requiring 120 km reach
• Point‑to‑point fiber connections for enterprise or industrial sites
• Upgrading switch or router ports to single‑mode fiber uplinks

Key specifications

• Data rate: 1.25 Gbps
• Optical wavelength: 1250 nm
• Maximum reach: up to 120 km over single‑mode fiber
• Connector type: SFP form factor with optical LC interface (single‑mode)
• Hot‑swappable operation for live equipment replacement
• Typical power consumption: low (suitable for rack and chassis installations)

How to use

Insert the SFP transceiver into an empty SFP slot on a compatible switch, router or media converter while the device is powered on; the module is hot‑swappable so no system shutdown is required. Terminate single‑mode fiber with the appropriate connectors and ensure correct polarity before connecting to the transceiver. After insertion and fiber connection, verify link status and data rate in the host device management interface and confirm signal levels meet expected margins for long‑reach operation.

Recommendations

Use single‑mode fiber with appropriate attenuation and splicing quality for distances up to 120 km, and include optical amplifiers or dispersion compensation only if system design and link budget require them. Check compatibility lists of the network equipment vendor when deploying third‑party transceivers to ensure full interoperability and consider testing in the target environment before large‑scale rollout.
