SFP-transceiver CBO SFP-1G-ZX-120KM-MR-BO 1,25 Gbit/s LC ZX 120 km

The BlueOptics SFP-1G-ZX-120KM-MR-BO is a single-mode SFP transceiver module that supports a 1.25 Gbps data rate and uses an LC duplex connector with ZX wavelength. Designed for long-distance fiber links, this module enables reliable point-to-point connectivity up to 120 km when installed in compatible switches, routers or media converters. The transceiver is suitable for extending uplinks, aggregating traffic between sites and maintaining stable optical connections in telecom and enterprise networks.

Advantages

This SFP transceiver provides long-reach optical connectivity with a footprint that fits standard SFP ports. Its single-mode design and ZX wavelength allow transmission over extended distances up to 120 km without intermediate amplification in appropriate network conditions. The LC connector ensures broad compatibility with common fiber patch cords and network equipment. The module supports hot-swapping for maintenance and upgrades without shutting down host devices.

Suitable for

• Long-distance fiber uplinks between buildings or data centers
• WAN links and metro access networks
• Connecting switches, routers and media converters over single-mode fiber
• Extending backbone or aggregation links in campus and carrier networks

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: single-mode
• Connector: LC duplex
• Wavelength: ZX (long-wavelength single-mode)
• Maximum reach: up to 120 km (link-dependent)
• Form factor: SFP (hot-pluggable)

How to use

Install the transceiver into an empty SFP port on a compatible switch, router or media converter until it seats securely, then connect single-mode LC fiber patch cords to the transmit and receive ports following the equipment’s labeling. Verify link status through the host device interface and ensure fiber polarity and optical budget meet the required link parameters for the intended distance. Use appropriate device configuration for 1.25 Gbps operation if manual settings are required.

Recommendations

Use high-quality single-mode fiber with correct attenuation characteristics and maintain clean LC connectors to achieve reliable transmission over long distances. Confirm the optical budget and dispersion limits for links approaching 120 km and consider installing additional amplification or dispersion compensation only when necessary. Check device compatibility lists or consult vendor guidance before deployment.
