## Summary description

SFP28 optical active cable CBO 7Z57A03545-BO is a 20-meter, 25 Gbit/s certified cable for high-speed server and switch interconnects. Designed for SFP28 ports, it provides a fixed-length fiber/link solution without separate transceivers, simplifying installation and reducing module inventory. Suitable for data centers and network upgrades requiring reliable 25 G connectivity over 20 m.

## Long description

SFP28 optical active cable CBO 7Z57A03545-BO 20 m 25 Gbit/s is a factory-terminated, fixed-length 20-meter fiber solution designed for direct connection between devices with SFP28 ports. The cable supports 25 Gbit/s line rates and provides a compact, low-power alternative to separate transceivers and patch cords, simplifying server-to-switch and switch-to-switch interconnects in data centers and network closets. It is intended for environments that require reliable 25 G connectivity over a 20 m reach while reducing module inventory and easing installation.
Advantages
The SFP28 optical active cable delivers a single-component link that eliminates the need to install separate optical transceivers and short patch cords, reducing installation time and potential points of failure. Its fixed 20 m length ensures predictable optical performance and eliminates connector mating variability. The integrated active components maintain signal integrity for 25 Gbit/s operation and typically lower power consumption and cost compared with discrete transceiver plus fiber assemblies. Compatibility with SFP28 ports provides plug-and-play operation for standard 25 G network equipment.
Suitable for
 25 G server-to-switch uplinks within data center racks and across adjacent aisles
 Switch-to-switch connections in top-of-rack or end-of-row deployments
 Network upgrades from 10 G to 25 G where a 20 m reach is required
 Environments aiming to reduce transceiver inventory and simplify cabling
Key specifications
 Supported data rate: 25 Gbit/s
 Connector type: SFP28 form-factor plug
 Cable type: Active optical cable (factory-terminated, fixed length)
 Length: 20 meters
 Optical reach: Designed for reliable 20 m operation
 Power: Integrated active components for signal conditioning (low-power design)
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the devices to be linked. Ensure both devices support 25 G operation and that port settings (speed/encapsulation) are configured appropriately. Avoid excessive bending of the cable near the connector and secure routing to prevent strain. No additional transceivers or patch cords are required; the link should be recognized by modern network equipment as a standard SFP28 connection. If devices require vendor-specific EEPROM data, verify firmware compatibility or consult device documentation.
Usage recommendations
Store and handle the cable following standard fiber handling practices: avoid tight bends, protect connector end-faces from contamination, and maintain ambient operating conditions within the equipment specifications. For best results in mixed-vendor environments, confirm that both ends support SFP28 active optical cables and verify link negotiation after installation.
