SFP transceiver CBO SFP-1G-MMF-2KM-PS-BO 1.25 Gbps multimode fiber, 2000 m reach

CBO SFP-1G-MMF-2KM-PS-BO is an SFP optical transceiver module designed for 1.25 Gbps duplex multimode fiber links with a reach up to 2000 meters. The compact, hot‑swappable form factor fits standard SFP slots in switches, routers and media converters to provide optical uplinks or access links in LAN and metro environments. The transceiver supports reliable data transmission over multimode fiber and is intended for straightforward integration into existing fiber infrastructures.

Advantages

The transceiver offers 1.25 Gbps data rate for gigabit Ethernet applications over multimode fiber, combining long reach for multimode connections with a small SFP profile that enables flexible deployment in constrained equipment bays. Hot‑swappable capability allows on‑the‑fly replacement without powering down the host device. The module provides duplex optical connectivity suitable for uplinks, aggregation or access links while maintaining compatibility with standard SFP interfaces.

Suitable for

• Gigabit Ethernet uplinks between switches and routers over multimode fiber
• Access links in enterprise LAN and campus networks
• Media converters and modular optical line cards with SFP slots
• Network segments requiring up to 2000 m reach on multimode fiber

Key specifications

• Data rate: 1.25 Gbps
• Fiber type: Multimode fiber (MMF)
• Maximum reach: 2000 meters over multimode fiber
• Connector: Duplex optical interface (LC-style duplex)
• Form factor: SFP (small form-factor pluggable), hot‑swappable

How to use

Install the module into a compatible SFP slot on the network device following the device manufacturer’s guidance. Ensure the host port is configured for the intended link speed and duplex settings if required. Connect duplex multimode fiber patch cords to the module’s optical ports; observe correct transmit/receive orientation. After insertion, verify link status and perform any necessary network configuration or testing to confirm proper operation.

Recommendations

Use high-quality multimode fiber and appropriately rated patch cords to achieve the specified 2000 m reach. Maintain clean connector endfaces and follow standard ESD precautions during handling. Confirm compatibility with the host device’s SFP support list and firmware recommendations to ensure reliable operation.
