SFP fiber transceiver CBO SFP-1G-ZX-120KM-PA-BO 1.25 Gbps LC multimode/SMF ZX 120 km

The BlueOptics SFP fiber transceiver SFP-1G-ZX-120KM-PA-BO is a single‑port SFP module that supports 1.25 Gbps data rate and uses an LC connector with ZX wavelength characteristics for long‑reach links up to 120 km. Designed primarily for single‑mode fiber (SMF) networks, the module provides a compact small form factor compatible with standard SFP slots and is intended for gigabit uplinks, metro connections and long‑distance backbone links where extended reach and reliable optical transmission are required.

Advantages

This SFP transceiver delivers a standardized 1.25 Gbps interface in a compact SFP package, allowing straightforward integration into switches, routers and other network devices that accept SFP modules. The ZX wavelength design enables long‑distance connectivity up to 120 km over single‑mode fiber, reducing the need for intermediate regeneration or additional active equipment. The LC connector ensures wide compatibility with common fiber patching and cabling systems.

Suitable for

• Long‑reach single‑mode fiber links up to 120 km
• Gigabit uplink ports on switches and routers
• Metro area network and backbone connectivity
• Service provider and enterprise WAN interconnects

Key specifications

• Form factor: SFP (small form‑factor pluggable)
• Data rate: 1.25 Gbps
• Fiber type: single‑mode fiber (SMF)
• Wavelength: ZX (long‑reach optical window)
• Maximum reach: up to 120 km
• Connector type: LC duplex

How to use

Install the transceiver into an available SFP slot on the network device while the device is powered according to the vendor’s hot‑swap recommendations. Connect the LC duplex fiber cable to the module ensuring correct polarity and secure mating. Configure the connected network equipment for the desired 1 G interface settings and verify link status through device management interfaces. Observe standard fiber handling and electrostatic discharge precautions during installation and maintenance.

Recommendations

Use this transceiver with single‑mode fiber and LC‑terminated patch cords rated for long‑reach transmission. Verify device compatibility with the SFP form factor and 1.25 Gbps optical interface before deployment, and plan for appropriate fiber testing and monitoring to maintain link performance over long distances.
