Fiber Optic SFP Transceiver CBO SFP-1G-MMF-2KM — 1G, multimode, 2 km

CBO SFP-1G-MMF-2KM is a 1 Gigabit multimode fiber SFP transceiver designed for short-range optical links up to 2 km. The module offers hot-pluggable SFP form factor connectivity for switches, routers and media converters, enabling standard 1G Ethernet links over multimode fiber. It is suitable for data center uplinks, campus networks and enterprise connections that require stable and interoperable 1G fiber transport.

Advantages

The transceiver supports 1G Ethernet on multimode fiber with a reach of up to 2 km, providing a compact, hot-swappable solution for network equipment. It follows common SFP electrical and optical interfaces for broad compatibility with networking hardware and reduces the need for immediate device downtime during upgrades or replacements. The module’s multimode operation simplifies short-range fiber cabling while maintaining low-power consumption and predictable performance.

Suitable for

• Short-range 1G links between switches and routers within data centers
• Campus and building backbone connections over multimode fiber
• Fiber uplinks for small and medium enterprise networks
• Media converters and network interface modules requiring SFP 1G ports

Key specifications

• Data rate: 1 Gbit/s
• Fiber type: multimode fiber (MMF)
• Maximum reach: up to 2 km over multimode fiber
• Form factor: SFP (Small Form-factor Pluggable)
• Optical interface: duplex fiber connector (LC compatible)
• Hot-pluggable: yes
• Typical power consumption: low (industry-standard SFP power class)

How to use

Insert the SFP module into a compatible SFP slot on a switch, router or media converter until it locks into place. Connect multimode fiber patch cables to the module’s duplex optical interface, ensuring correct transmit/receive orientation. After insertion, verify link status on the host device and configure the network interface as required for 1G Ethernet operation. To remove, follow the device manufacturer’s hot-swap procedure and pull the module out using the latch mechanism.

Recommendations

Use multimode fiber with appropriate attenuation and patch panels for distances up to 2 km; choose OM3/OM4 multimode fiber where available to maintain margin and simplify cabling. Verify compatibility with the host device and firmware, and avoid exposing the transceiver optical ports to dust — use dust caps during storage and installation.
