SFP transceiver CBO SFP-1G-MMF-2KM-VA-BO 1.25 Gbps multimode fiber, 2 km

The BlueOptics SFP-1G-MMF-2KM-VA-BO is a Small Form-Factor Pluggable (SFP) optical transceiver module designed for 1.25 Gbps Ethernet links over multimode fiber. It supports transmission distances up to 2 km on suitable multimode fiber and is intended for installation in network switches, routers and other devices with SFP ports. The module complies with standard SFP electrical and optical interfaces and is suitable for short-to-medium range fiber connections in LAN, campus and metro aggregation segments.

Advantages

This transceiver offers a compact, hot-swappable SFP form factor that simplifies upgrades and maintenance without powering down equipment. It provides a standardized 1.25 Gbps data rate for compatibility with Gigabit Ethernet and other 1.25 Gbit/s applications over multimode fiber. The module is engineered for reliable optical performance across supported distances and supports standard SFP electrical signaling to work with a wide range of network hardware.

Suitable for

• Gigabit Ethernet links over multimode fiber within buildings or between adjacent sites
• Campus and metro aggregation where moderate distances (up to 2 km) are required
• Network switches and routers equipped with SFP ports
• Redundant links and uplinks in enterprise LAN and data closet environments

Key specifications

• Connector type: LC duplex
• Fiber type: multimode fiber (MMF)
• Supported data rate: 1.25 Gbps
• Maximum transmission distance: up to 2 km on appropriate multimode fiber
• Form factor: SFP (Small Form-Factor Pluggable), hot-pluggable
• Wavelength range: suitable for multimode fiber optics (short wavelength multimode operation)
• Optical interface: duplex multimode

How to use

Insert the SFP transceiver into an available SFP slot on a compatible switch or router until it clicks into place, observing ESD precautions. Connect the LC duplex multimode fiber patch cable to the transceiver, matching transmit and receive channels. Configure the device port as required by your network operating system, setting link speed and duplex if manual configuration is needed. Monitor link status LEDs and management interfaces to verify an operational connection.

Recommendations

Use multimode fiber of the appropriate specification and quality to achieve the stated 2 km range; verify connector cleanliness and perform optical testing after installation. Ensure the host device supports SFP modules and the 1.25 Gbps data rate. Keep spare transceivers stored in anti-static packaging and handle modules by the housing to avoid contaminating the optical interfaces.
