SFP28 transceiver CBO SFP28-25G-ESR-NA-BO 25 Gbps LC multimode 300 m

CBO SFP28-25G-ESR-NA-BO is a 25 Gbps SFP28 optical transceiver with an LC duplex interface for multimode fiber. Engineered for short-reach 25G Ethernet and data center interconnects, this compact hot-pluggable module supports reliable links up to 300 meters over suitable multimode fiber. The module is compatible with standard SFP28 ports in switches, routers and servers and is intended for straightforward integration where high-density, high-speed connectivity is needed.

Advantages

The SFP28 transceiver offers a high data rate of 25 Gbps in a small form factor that supports hot-plug replacement and easy field upgrades without powering down equipment. Its LC multimode interface provides stable short-reach performance up to 300 meters, enabling flexible cabling options in server rooms and distribution areas. Built for industry-standard SFP28 slots, the module simplifies deployment in mixed-vendor environments and reduces footprint compared with larger optical transceivers.

Suitable for

• 25G Ethernet connections in data centers and enterprise networks
• Server-to-switch and switch-to-switch short-reach links
• Top-of-rack and aggregation layer interconnects using multimode fiber
• High-density ports where compact, hot-pluggable modules are required

Key specifications

• Data rate: 25 Gbps
• Fiber type: Multimode fiber (MMF)
• Connector: LC duplex
• Maximum reach: Up to 300 meters (dependent on fiber type and link budget)
• Form factor: SFP28 hot-pluggable module

How to use

Install the SFP28 transceiver into a compatible SFP28 port on switches, routers or servers until it latches securely. Connect LC duplex multimode fiber patch cables, observing correct polarity for transmit and receive pairs. After insertion, verify link status and speed in the equipment management interface; the module supports auto-negotiation where supported by the host device. For removal, release the latch and extract the module carefully to avoid fiber stress.

Recommendations

Use suitable multimode fiber with appropriate modal bandwidth and verify that the total link loss meets the transceiver's budgets for reliable operation up to 300 m. Keep dust caps on unused ports, avoid excessive bending of fiber cables, and follow equipment vendor guidelines for optical modules and compatibility verification.
