Transceptor SFP28 CBO SFP28-25G-ESR-PT-BO 25 Gbit/s LC multimodo 300 m

The CBO SFP28-25G-ESR-PT-BO is a hot-pluggable SFP28 optical transceiver that supports a 25 Gbit/s data rate with an LC connector for multimode fiber up to 300 m. It is designed for use in switches, routers and network interface cards to provide high-speed uplinks and short-reach connections in data centers and enterprise networks. The compact SFP28 form factor enables straightforward installation and replacement without powering down equipment, supporting flexible network maintenance and upgrades.

Advantages

This SFP28 transceiver offers single-lane 25 Gbit/s performance over multimode fiber, low power consumption and compatibility with common networking equipment that accepts SFP28 modules. The LC duplex interface and multimode support allow cost-effective short-reach links up to 300 meters, while the hot-pluggable design simplifies swaps and expansions in live systems. Thermal and signal specifications are tuned for stable operation in rack and server environments.

Suitable for

• 25 Gbase-SR short-reach uplinks in data center switches and leaf-spine fabrics
• Server to switch connections using multimode fiber
• Network interface cards (NICs) requiring 25 Gbit/s optical links
• Campus and enterprise wiring for high-bandwidth aggregation links

Key specifications

• Data rate: 25 Gbit/s single-lane
• Fiber type: multimode fiber (MMF)
• Maximum reach: up to 300 meters on multimode fiber
• Connector type: LC duplex
• Form factor: SFP28 hot-pluggable module
• Typical application: short-reach optical links in data centers and enterprise networks

How to use

Insert the SFP28 transceiver into a compatible SFP28 port on a switch, router or NIC while the host device is powered on; the module is hot-pluggable and recognized by the host firmware. Connect LC duplex multimode fiber patch cords, ensuring correct polarity and clean connectors to maintain signal integrity. Verify link status and negotiated speed on the host device and monitor for alarms or alarms in the management interface. For best results, use OM3/OM4 multimode fiber for longer reaches within the specified 300 m limit.

Recommendations

Maintain clean fiber connectors and use dust caps when the transceiver is not in use. Confirm compatibility with the host device and review firmware or vendor interoperability notes if link issues arise. For installation in dense racks, ensure adequate airflow and observe the module’s power dissipation limits to prevent thermal throttling.
