Transceptor de fibra ótica SFP28 CBO BO27Q856S3D 25G ESR módulo

The BlueOptics SFP28 BO27Q856S3D 25G ESR module is a compact fiber optic transceiver designed for 25 Gigabit Ethernet links. This SFP28-form factor unit provides a small, hot-pluggable interface for switch-to-switch connections and optical uplinks in data center and enterprise networks. It supports short-to-medium reach multimode or single-mode optical transmission (ESR class) and is intended for reliable, high-speed connectivity where space and port density are important.

Advantages

The SFP28 fiber optic transceiver offers a compact footprint and hot-swappable operation for minimal downtime during installation or replacement. Its 25G data rate supports high-throughput applications, while ESR optical reach covers common intra-data-center and campus links. The module is compatible with industry-standard SFP28 ports, enabling straightforward integration with compatible switches and optical equipment without requiring chassis changes.

Suitable for

• 25 Gigabit Ethernet uplinks between switches and routers
• Server-to-switch high-speed connections in data centers
• Optical links within enterprise and campus networks
• Port density upgrades where SFP28 form factor is required

Key specifications

• Form factor: SFP28 small form-factor pluggable
• Data rate: 25 Gigabit Ethernet
• Optical reach: Extended short reach (ESR) for short-to-medium links
• Interface: Optical fiber (compatible with standard SFP28 ports)
• Hot-pluggable design for tool-free installation
• Compact dimensions suitable for high port density switches

How to use

Install the transceiver into an available SFP28 port on a compatible switch, router, or host adapter while the device is powered on or off according to the equipment vendor's guidance. Connect the optical fiber patch cable to the module's optical interface, ensuring correct fiber type and connector polarity. Verify link status on the network device and configure interface parameters such as speed and auto-negotiation if required. For replacement, remove the module by disengaging the latch and pulling straight out, then insert the new module until it seats securely.

Recommendations

Use certified fiber cabling and compatible connectors to maintain signal integrity and meet the expected ESR reach. Verify hardware compatibility with the switch vendor's supported transceiver list and update device firmware if necessary. Handle the optical interface with dust caps when not connected and avoid touching the fiber endface to prevent contamination.
