Transceptor SFP28 25G de fibra ótica CBO SFP28-25G-ESR BO27Q856S3D — 25 Gigabit Ethernet, formato SFP28

CBO SFP28-25G-ESR BO27Q856S3D is a 25 Gigabit Ethernet SFP28 fiber optic transceiver in a compact SFP28 form factor designed for high-speed uplinks and server connections. It supports 25Gbase operation over single-mode fiber and is intended for use in switches, routers and network interface cards that accept SFP28 modules. The module delivers low-latency, high-throughput connectivity for data center fabrics and enterprise aggregation layers while preserving slot density in modern network equipment.

Advantages

The transceiver offers a standardized SFP28 footprint for easy hot-plug installation and broad compatibility with 25G-capable hardware. It provides stable 25 Gigabit Ethernet performance with low power consumption and a small form factor that helps maintain high port density. Designed for fiber links, the module supports reliable long-reach connections and consistent signal integrity for demanding network environments.

Suitable for

• 25G uplinks between switches and aggregation devices
• Server connections to 25G network interface cards (NICs)
• Data center leaf-spine fabrics requiring low-latency links
• Enterprise campus backbones and high-bandwidth distribution
• Fiber-based access and metro connections where 25G is required

Key specifications

• Interface: SFP28 form factor
• Data rate: 25 Gigabit Ethernet
• Medium: Single-mode fiber (optical)
• Transmission type: Duplex fiber
• Typical power consumption: low-power SFP28 class (device dependent)
• Operating temperature: commercial range suitable for standard networking equipment

How to use

Install the module into an empty SFP28 port on a compatible switch, router or server NIC while the host device is powered on or off according to the equipment manual. Connect single-mode duplex fiber patch cables to the TX and RX ports, ensuring correct polarity. Verify link status and speed on the host device’s management interface; the module will negotiate 25G operation with a compatible remote port. Monitor optical power and link health through the host system or management tools as part of routine network maintenance.

Recommendations

Use manufacturer-recommended fiber types and patch cords, maintain correct fiber polarity, and avoid sharp bends or excessive stress on fibers. Ensure that the host device firmware and drivers support SFP28 25G modules. For long-term reliability, perform periodic checks of optical power levels and environmental conditions in the equipment rack.
