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

SFP transceiver CBO SFP-1G-MMF-2KM is a 1 Gbps optical module for multimode fiber links with reach up to 2 km. The module uses a small form-factor pluggable design that supports hot-swapping and is suitable for uplinks on switches, routers and firewalls. It is intended for short-range optical connections in data center, campus and enterprise environments where reliable gigabit connectivity over multimode fiber is required.

Advantages

The transceiver offers a straightforward upgrade path for existing copper ports to 1 G optical links and enables flexible network architecture through hot-pluggable installation. Its multimode capability and 2 km reach make it practical for typical campus and building-to-building links while keeping latency and power consumption low. Compatibility with common networking equipment ensures easy integration and predictable performance for standard gigabit Ethernet applications.

Suitable for

• Short-range fiber uplinks between switches and access points
• Connections between server racks within data centers
• Campus backbone links and inter-building connections up to 2 km
• Upgrading firewall or router ports to optical 1 Gbps links

Key specifications

• Data rate: 1 Gbps (Gigabit Ethernet)
• Fiber type: Multimode fiber (MMF)
• Maximum reach: 2 km over appropriate multimode fiber
• Form factor: Small Form-Factor Pluggable (SFP), hot-pluggable
• Connector type: LC duplex (industry-standard optical connector)
• Power consumption: low-power single-socket operation suitable for network equipment
• Operating temperature: standard commercial temperature range for networking modules

How to use

Insert the SFP transceiver into an available SFP slot on compatible network equipment until it seats securely; the module supports hot-plug insertion and removal. Connect a multimode duplex LC fiber patch cable between the transceiver and the remote optical device, observing correct transmit/receive orientation. Verify link status through the device management interface and monitor operational LEDs on the host equipment to confirm signal presence and proper operation.

Recommendations

Use appropriate grade multimode fiber and certified LC patch cords to achieve the specified 2 km reach. Ensure that the host device supports third-party SFP modules or is configured to accept modules of this type. For best signal integrity, keep fiber runs within the recommended distance and maintain proper fiber handling practices to avoid bends or contamination.
