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

CBO SFP-1G-MMF-2KM is a 1 Gigabit SFP transceiver designed for multimode fiber links with a maximum reach of 2 km. This module follows the standard SFP form factor and supports hot-pluggable insertion into compatible SFP ports. It is intended for establishing reliable Ethernet connections over multimode fiber between network switches, routers and media converters where moderate fiber distances are required.

Advantages

The transceiver provides a compact, industry-standard SFP solution for 1 Gbps links, enabling easy upgrades or replacements without altering existing equipment. Its multimode fiber support and 2 km reach offer a balance between cost and distance for campus, building-to-building or data closet interconnects. Hot-pluggable capability allows maintenance or swap-out without powering down connected devices, and standardized electrical and optical interfaces ensure interoperability with a wide range of network hardware.

Suitable for

• Short- to medium-distance Ethernet uplinks over multimode fiber
• Interconnects between switches, routers and media converters
• Campus and enterprise links where 2 km maximum reach is sufficient
• Network equipment upgrades or replacements requiring SFP form factor

Key specifications

• Data rate: 1 Gigabit per second (1 Gbps)
• Fiber type: Multimode fiber (MMF)
• Maximum reach: up to 2 kilometres
• Form factor: Small Form-factor Pluggable (SFP), hot-pluggable
• Interface: Optical fiber interface compatible with standard SFP ports
• Typical application: Ethernet links and uplinks between network devices

How to use

Install the SFP module into an empty SFP slot on your switch, router or media converter until it clicks into place, following the equipment manufacturer’s guidance. Connect appropriate multimode fiber patch cables to the module’s optical connector, ensuring proper connector type and polarity. After insertion, verify link status and speed in the host device’s management interface. For removal, follow hot-swap procedures recommended by the network device vendor to avoid traffic disruption.

Recommendations

Use compatible multimode fiber patch cables and follow polishing/cleaning best practices for connectors to maintain signal quality. Verify compatibility with the host device and, where applicable, configure link settings on switches or routers to match the 1 Gbps operation. Avoid bending the fiber beyond recommended radius and keep the module dust caps in place when not connected.
