SFP Transceiver CBO SFP-1G-MMF-2KM 1G multimode fiber module, 2 km reach

CBO SFP-1G-MMF-2KM is an SFP transceiver module designed for 1 Gbps Ethernet links over multimode fiber with an approximate reach of 2 km. Engineered for installation in network devices with SFP ports, this module enables fiber uplinks between switches, patch panels and access equipment in campus, enterprise and carrier access environments. The product supports standard 1G Ethernet signaling and provides a compact, hot‑pluggable form factor suitable for modular networking hardware.

Advantages

The multimode SFP transceiver offers reliable 1 Gbps throughput with low power consumption and a small footprint. Its hot‑swappable design simplifies installation and maintenance without powering down the host device. Compliance with common SFP mechanical and optical interfaces ensures broad compatibility with switches, routers and fiber patching infrastructure. The module's 2 km reach over multimode fiber supports short‑to‑medium distance links common in campuses and data center interconnects.

Suitable for

• Fiber uplinks between switches and aggregation devices
• Patch panel to switch connections in campus networks
• Enterprise building-to-building multimode fiber links
• Network equipment requiring SFP 1G modules for optical connectivity

Key specifications

• Data rate: 1 Gbps (supported for standard 1G Ethernet)
• Fiber type: Multimode fiber (MMF)
• Maximum reach: approximately 2 km over multimode fiber
• Interface: SFP form factor, hot‑pluggable
• Optical wavelength: suitable for multimode operation (VCSEL/LED family optics)
• Power consumption: low typical operating power for SFP modules

How to use

Install the module into an empty SFP slot of a powered network device until it latches; the device should recognize the transceiver and negotiate the 1G link automatically with a compatible remote port. Connect the multimode fiber patch cables using the appropriate connector types at both ends and ensure proper fiber routing and strain relief. Monitor link status via the host device LEDs or management interface and verify optical parameters if available. For removal, unlatch and pull the module straight out while the host device is powered on, following the hot‑swap procedure.

Recommendations

Use multimode fiber cabling rated for the intended distance and maintain clean fiber connectors to ensure optimal signal integrity. Verify compatibility with the host device's SFP port and consult device documentation for any vendor interoperability notes. For critical links, perform optical power and link tests after installation and maintain spare modules for rapid replacement.
