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

CBO SFP-1G-MMF-2KM is a fiber optic SFP transceiver module that supports 1 Gbps data transmission over multimode fiber for link lengths up to 2 km. The module is intended for insertion into standard SFP ports on switches, routers and other network devices to establish short- to medium-range Ethernet connections. It is compatible with multimode fiber infrastructures used in campus, enterprise and data center environments and provides simple plug-and-play operation without manual configuration.

Advantages

The transceiver provides stable 1 Gbps connectivity over multimode fiber with a maximum reach of 2 km, reducing the need for electrical uplinks or media converters. Its small form-factor pluggable design enables hot-swappable installation and easy replacement. The module is designed for interoperability with standard SFP ports and typical multimode fiber cabling, offering low-power operation and minimal setup effort.

Suitable for

• Short- to medium-distance Ethernet links between switches and routers
• Campus and building backbone multimode fiber connections
• Server-to-switch or switch-to-switch connections in data centers and wiring closets
• Upgrading copper-to-fiber segments where multimode fiber is already installed

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: Multimode fiber (MMF)
• Maximum transmission distance: up to 2 km over appropriate multimode fiber
• Form factor: SFP (Small Form-factor Pluggable)
• Interface: Duplex fiber connection
• Operation: Hot-pluggable, plug-and-play
• Power consumption: low-power SFP class device

How to use

Insert the CBO SFP-1G-MMF-2KM module into an empty SFP slot of a compatible network device while the device is powered on or off according to the device manual; the module supports hot-swapping. Connect the duplex multimode fiber patch cable to the transceiver’s LC duplex connector, ensuring correct transmit/receive orientation. Configure the network interface on the connected devices as required for 1 Gbps operation; in most environments the link will be negotiated automatically. Monitor link status and diagnostics via the host device as needed.

Recommendations

Use OM1/OM2/OM3/OM4 multimode fiber types as supported by your network design and verify fiber attenuation and connector condition to achieve the specified reach. For reliable performance, keep fiber connectors clean, use appropriate LC duplex patch cords, and check compatibility with the host device’s SFP port and firmware. When deploying in data center or campus environments, follow grounding and cable management best practices to maintain signal integrity and ease of maintenance.
